Introduction
Congratulations! You have chosen the Mytrex MXD Personal Emergency Response System
(PERS), which you have obtained through the following service provider:
[Providers name
Providers address
Business Toll free number
Response Center Toll Free Number (if different from business number)
Fax Number
Email address
Web site]
The MXD has been created to provide you comfort, reassurance, and peace of mind by making it
possible for help to be just a touch of a button away.
Pressing your waterproof personal help button (PHB) will immediately activate the MXD PERS
unit. Within seconds, your response center will be notified of your need for assistance. When a
call for help is received, the response center’s computers provide an attendant with all of your
personal information. The attendant will talk to you through the MXD unit's speakerphone. The
attendant will then telephone your family, friends, or emergency services based on the type of
assistance you need. Even if you cannot hear or speak to the attendant, help will be summoned
for you.
The MXD unit is fast and simple to install. Your service provider's representative may connect
the MXD unit during an installation visit, you may elect to do it yourself, or you may ask a
friend or relative to install it for you.
To ensure that you always receive the fastest response time possible, it is very important that you
do the following:
Notify your service provider of any changes that should be made to your personal
account information. You can update your account by calling your service provider
or by pressing your PHB and relaying the information to the attendant over the
speakerphone. Your response center needs to be aware of changes to your address,
telephone number, responder information, medical history, allergies, doctor information,
hidden key location, and other information that you wish to have on file.
Test your MXD unit at least once a month by pressing your PHB.
Always wear your PHB!
This User’s Manual has been designed to help you make the most of your MXD PERS system. If
you have any questions or concerns after reading this manual, please contact your service
provider.

Base Unit Help Button (Figure 1)
Normally, pushing the large blue Help Button on the front of your base unit causes the unit to send a
“Help needed” message to the response center. The Help Button also is used with the T/L button to
conduct range tests and to program the MXD unit to recognize PHBs or other accessories.
STATUS Light (Figure 1)
A small STATUS light is located on the lower left edge of the unit’s large “Help” button. The STATUS
light will display steady or flashing lights, in either red, green or orange color, depending on the status of
the unit. See Page 13 for a more detailed description of the STATUS light signals and their meaning.
T/L (Test/Learn) Button (Figure 2)
The white T/L (Test/Learn) Button is located on the rear of your MXD unit. It is used to place your MXD
unit into special operating modes to conduct PHB range tests, to program PHBs and other accessories,
and to allow technical personnel to diagnose problems and adjust the unit.

PHB or the Base Unit Help Button if the unit is properly installed. The unit will sound two quick tones
when it is reset. If voice announcements are enabled the unit will announce, “System Ready.”
The RESET Button may also be used to cancel your call for help if your MXD unit is inadvertently
activated. However, to cancel a call for help the RESET Button must be pressed within 10-15 seconds of
activation; otherwise, the unit will already be communicating with the response center. The response
center is staffed 24 hours a day, therefore, it is best to allow your MXD unit to complete the call and tell
the attendant that you accidentally activated your MXD unit.
Personal Help Button (Figure 3)
Each MXD unit is supplied with one or more Personal Help Buttons (PHBs). The PHB is a small
waterproof pendant that may be worn around the neck on a breakaway cord, or may be worn attached to a
wrist band. When pressed, the PHB sends a “Help needed” radio signal to the MXD base unit, causing it
to call the monitoring center. Within a few seconds, an attendant will talk to you through your MXD base
unit’s speaker to determine if help is needed. The PHB transmitter and the base unit receiver are carefully
designed to ensure that the base unit can detect the PHB’s signal at distances of up to 600 feet away from
the base unit.
Setup Guide
Your MXD is designed to work with many different types of telephone technologies, including traditional
Plain Old Telephone Service (POTS), Voice over Internet Protocol (VoIP), cable company telephone
systems, and Digital Subscriber Line (DSL) service. This section provides instructions for setting up the
MXD to work with POTS, DSL, and VoIP telephone service. Telephone systems provided by cable
companies generally require connections similar to POTS telephones. Please contact your service
provider if none of the following setups work for your system.
Initial Setup steps for Any Type of System:
For any of the following setups:
1. Locate a live telephone jack with an electrical outlet nearby. The electrical outlet must
not be controlled by a light switch. Select a location where the MXD unit can be placed
on a flat, horizontal surface and where it will be located centrally, in a part of your home
that is used frequently. While it is recommended that the MXD be placed on a flat,
horizontal surface, it can be wall mounted if necessary. The MXD unit should be located
away from the immediate vicinity of mechanical noise sources, i.e. oxygen generators,
electrical equipment, and all appliances such as televisions or stereos.
2. If a telephone handset has not been plugged into the telephone jack and used recently,
plug a telephone handset into the jack and make a call using the handset to a working
telephone number. Confirm that the call goes through and that both parties can hear and
speak to one another.
3. Unplug the telephone handset cord from the wall jack.
System Setup for Locations with Plain Old Telephone Service (POTS)
Figure 5 is a general representation of a setup for locations connected to traditional telephone service.

MXD Users Manual

Figure 5. MXD Connections for Traditional (POTS) Telephone Service
1. Complete the installation steps common to all setups that are listed on Page 6.
2. Plug your telephone handset cord into the jack on the back of the MXD unit marked
“PHONE”. If your home is equipped with DSL service, see configurations on page
8.
3. Find the telephone cord that was shipped with your MXD unit, with a larger modular
plug on one end and a smaller modular plug on the other end. Plug the smaller end into
the phone jack on the wall, and the larger end into the jack on the back of the MXD
marked “WALL”.
NOTE: When your MXD unit calls the response center, the telephone and any
other device connected to the PHONE jack on the rear of your MXD unit will be
disconnected during the call. This means if this telephone is off hook, your MXD
unit can still contact the response center. If there are other extensions of the same
telephone number in your home that are off-hook when your MXD unit needs to
place a call, it will not be able to unless the local telephone company has installed an
RJ31X jack or devices called “Line Grabbers”are properly installed on each
telephone extension. The RJ31X jack allows the MXD unit to disconnect any
telephone in the house that may be in use. IF you elect to have an RJ31X installed,
contact your service provider and ask for an RJ31X telephone cord, Mytrex part
number RA400-RJ31X. If you elect to use Line Grabbers, contact your service
provider for ordering and installation instructions.
4. Plug the power transformer into an AC outlet. Verify that the outlet is not controlled by
a light switch.
5. The MXD unit will automatically turn on and announce, “System Ready.”The small
“status” light on the lower left edge of the unit’s large “Help” button will show a steady
green light. This indicates that the unit is connected properly to the telephone circuit
and AC power. If the telephone is connected improperly, the unit will announce, “
Please Check Telephone Connections.”Please see page 20 for information on the

MXD Users Manual
April 5, 2012
Page 8 of 26
status light combinations that will display if the unit is not connected properly to the
telephone system and electrical power, and for troubleshooting instructions.
6. Test the range of the PHB to make sure it works throughout your home and yard as needed.
It may be helpful to have a second person assist with this range test, with one person staying
by the base unit and the other person walking to all areas of the home and yard with the
PHB. To conduct the test:
Locate the T/L button located on the rear of the MXD unit. Press and release the
T/L button one time. The unit will announce, “Range Test Mode.”
Immediately press and hold down the PHB. A steady tone will sound from the
base unit speaker as long as the base unit is detecting the pressed PHB.
Walk around the home and yard while pressing the PHB, and check for the
steady tone from the base unit speaker. Check all areas of the home and yard to
make sure that the signal is received. Take note of any “dead zones” in which the
tone stops.*
To finish the Range Test, stop pressing the PHB and then press the black
“RESET” button on the rear of the MXD unit. The unit will announce, “System
Ready.”
If needed, relocate the base unit to eliminate dead zones and conduct another
range test.
*Metal objects, mirrors, aluminum siding, and other construction techniques can prevent the signal
from reaching the antenna inside your MXD unit. In such cases, there may be a small area in which
your MXD unit may not respond to your PHB. It may be helpful to relocate your MXD unit, or
move the object that is preventing the signal from being received. Also, electronic devices such as
clock radios, televisions, microwaves, and motors in some appliances can cause radio frequency
interference.
7. Initiate your first call to the response center simply by pressing your PHB. The MXD
unit will activate and call the response center. The unit will announce, “Calling for
Help,”and when it has connected to the response center will announce, “Call
Connected, Please Wait.”An attendant will then answer the call as soon as possible, will
welcome you as a customer, and will give you further information.
8. Note: The MXD unit is programmed to automatically call the response center a few
minutes after it has been installed for the first time, if the installer has not already
initiated a first call. This automatic call ensures that the response center is aware of the
new subscriber and knows to be ready to process any alarm calls. The unit usually is
programmed to make this call 30 minutes after installation, but the unit can be
programmed for a different delay period.
Setup for Telephone Service with DSL
In order to achieve reliable telephone connections with the response center, homes with DSL
telephone/computer service require additional installation steps. In the following sections, we have listed
the three configurations for a successful MXD/DSL installation, in order of commonality.

MXD Users Manual
April 5, 2012
Page 9 of 26
Follow the general installation procedures steps for POTS systems, and also complete one of the
following three configurations. Even with these configurations, it is possible that you will need to call
your service provider for more extensive troubleshooting.
1. Configuration 1: Plug-in DSL filters, supplied by the DSL provider, are installed between
telephone wall jacks and telephones in the home. If Configuration 1 has been installed in your
location, plug a DSL filter into the wall jack and then plug the MXD's telephone cord into the
DSL filter. See Figure 6 below.
NOTE: Some DSL filters supplied by DSL providers degrade the signals sent by the MXD to
the response center. If your MXD has problems communicating with the response center,
replace the DSL provider's filter with one from a different supplier. Contact your service
provider for assistance in obtaining a high quality DSL filter.
Figure 6. MXD Connections for Locations with a Self-Installed DSL Filter
2. Configuration 2: The DSL filter is hard wired by the DSL provider. In this instance the
location does not have self-installed filters on the telephone jacks, and the MXD unit should be
connected in the same manner as for traditional telephone service. See Figure 7 below.
Figure 7. MXD Connections for Locations with Hard-Wired DSL Filters
(Connections are the same as for standard telephone service)

3. Configuration 3. Alternative approach if neither of the above configurations works. If the
MXD cannot communicate with the response center using Configurations 1 or 2, you may be able to
connect the MXD unit into a phone jack built into the DSL Modem, which should be located near
your computer. See Figure 8 below.
Figure 8. MXD Connection to DSL Modem
Setup for Voice over Internet Protocol (VoIP)
Caution:The MXD PERS system is designed to be used with either traditional or VoIP based
telephone service. Mytrex strongly recommends that a Plain Old Telephone Service (POTS)
line be used for any type of alarm system, due to the much higher reliability of POTS.
However, increasing numbers of residences now are serviced by VoIP. There are differences in
the quality of service provided by different VoIP providers. VoIP telephone circuits are not as
reliable as standard telephone systems for various reasons. For example, many Internet
providers refuse to provide any service level guarantee, and clearly indicate in their contracts
that service may be interrupted at any time. Also, VoIP circuits are dependent on AC electrical
service to the residence, unless the VoIP system is equipped with a backup power supply. If
your telephone service experiences service interruptions, you may not be able to use your MXD
to contact your monitoring center. For these reasons, your VoIP provider should be chosen
carefully. Please evaluate the risks of not having your phone service available as part of
making the decision whether or not to use VoIP telephone technology. Mytrex, Inc. will not
assume any responsibility for alarms that are not received by the response center due to failures
or interruptions in any telephone system used by the subscriber.
The MXD system is connected to a VoIP telephone circuit in the same manner as when a standard
telephone circuit is used, and usually no technical adjustments are required. However, sometimes VoIP
systems are installed in a home in a way that one or more wall jacks are not in service, and that situation
can cause confusion when first installing the MXD unit.

MXD Users Manual

Connect and verify that your MXD system is connected to an operating VoIP line as follows:
7. Complete the initial installation steps described on Page 6, which are common to all
types of installations.
8. Find the telephone cord that was shipped with the MXD unit, with a larger modular plug
on one end and a smaller modular plug on the other end. Plug the smaller end into the
jack on the wall (or the jack on the VoIP modem if the house wiring is not used), and the
larger end into the jack on the back of the MXD unit marked “WALL”.
9. Plug the telephone handset cord into the jack on the back of the MXD unit marked
“PHONE”. Lift the telephone handset receiver that has been connected to the back of
the MXD unit, and confirm that there is a dial tone to verify that the MXD telephone
cord and the telephone handset cord are properly connected.
10. If no dial tone is present, check the connections again and correct any problems.
11. After connection to VoIP has been achieved, continue with steps 3 - 7 of the System
Setup for Locations with Plain Old Telephone Service (POTS). See Figure 9 below.

Frequently Asked Questions
How can the MXD help me to stay at my home and be safe?
The MXD allows you to call for help, even if you are alone and cannot reach or use the telephone.
Simply press the PHB and your MXD unit will call the response center where your unit will be
identified and connected to a trained attendant. Even if you cannot communicate with your response
center, attendants are trained to treat every received alarm as a call for help until they are sure that you
are okay. Simply press your PHB to activate your MXD unit at any time.
Is my Personal Help Button (PHB) waterproof?
Yes. Your PHB is waterproof, and should be worn in the bathtub or shower - both areas where
individuals have a high number of slips and falls.

MXD Users Manual
April 5, 2012
Page 12 of 26
Will my MXD unit affect my telephone?
Your MXD unit will not affect your telephone except when the unit has been activated by an alarm
signal. The MXD will disconnect any call in progress and take control of the phone line when it is
processing an emergency alarm, but will release the phone line for regular calls after your MXD is
disconnected from the response center.
What happens to my medical alert service if I go away for a period of time or move?
Your MXD unit is designed for flexible use. It may be taken with you on extended visits or to a new
residence. Please contact your service provider prior to moving or reinstalling your MXD unit.
Will my MXD unit work when I am at the market, or when I leave my house?
Your MXD unit will only work in and around the place where the base unit is installed. The base unit
can receive signals from the PHB from a distance of up to 600 feet. Instructions for testing the range of
your PHB may be found on page 8, step 6, of this User Manual.
Testing Your MXD unit
You are welcome to test your unit as often as you desire, but it is recommended that you test your MXD
unit at least every 30 days. Testing can usually be done in less than 3 minutes and usually will not
involve any of your responders. The purpose of testing is to provide security and peace of mind. This is
accomplished through regular usage, which promotes confidence and familiarity with your monitoring
center and your equipment.
Manual Test
Manually testing your MXD unit is easy. Simply press your PHB and wait for a response center
attendant to speak to you through the base unit. The following occurs during a Manual Test:
Immediately after you press your PHB, the unit will activate and announce, “Calling for Help.”
The unit will dial your response center, and when connected will announce, “Call Connected,
Please Wait.”
An attendant will soon talk to you over the unit's speaker, and ask if you need help. Tell them you
are doing a monthly test.
During each test, the attendant may verify your name, address, and telephone number.
Attendants are available 24-hours a day, allowing you to test at your convenience when you are
near the base unit and can talk to the attendant.
If it is difficult for you to hear or communicate clearly over your telephone or MXD unit, you
may want to have a friend or relative with you when you test.
Automatic Voice Test
Your MXD unit can be programmed to conduct an Automatic Voice Test. As mentioned above, it is
recommended that you test your unit regularly in order for you to gain familiarity and confidence in
your monitoring center and your equipment. When the MXD is programmed to conduct an Automatic
Voice test, the following sequence will occur:
The MXD unit automatically sends a test signal to your response center, during daytime hours.*
If your telephone is being used, the MXD unit waits until the line is available.
An attendant greets you over the MXD unit’s speaker to verify your test.
The MXD unit’s circuitry is tested, including the microphone, speaker and PHB.
The attendant may verify your name, address, and telephone number.
If a test is not performed according to schedule, your service provider may contact you to help
determine the cause.

MXD Users Manual
April 5, 2012
Page 13 of 26
Automatic Dial Test
If you prefer a silent test that requires no interaction, your MXD unit may be programmed to perform
the Automatic Dial Test instead. The following occurs during an Automatic Dial Test:
The MXD unit automatically sends a silent test signal during night time hours.*
If your telephone is being used, the MXD unit waits until the line is available.
The response center computer acknowledges the test signal.
The operation of the medical alert base unit is tested.
If the response center does not receive the expected test, your service provider may contact you to
help determine the cause.
*NOTE: We suggest setting the MXD to automatically test weekly, but your provider can schedule
automatic testing for any regular interval of days. If you choose to use the Automatic Dial Test, we still
encourage you to manually test the MXD unit at least once a month.
During routine monthly tests, your response center may verify your name, address, and
telephone number. This is to ensure that you will receive the fastest response time possible
during an emergency. It is very important that you notify your response center of any
information changes made on your account. You can do this by calling your response
center using the telephone number listed on page 2 of this manual, or by pressing your PHB
and relaying the information to the attendant.
Additional Use Instructions
Turning off the MXD
The MXD unit does not have an on/off switch. It will automatically turn on when first connected to an
AC power supply. In order to manually turn off the unit, unplug it from the AC power supply AND the
telephone line, and then hold down the T/L button for a few seconds, until the STATUS light on the edge
of the large console HELP button goes out. See Figure 9.
Figure 9. Close-up view of Mytrex MXD Rear Case
If it is not possible to unplug the AC power supply and the telephone line, the unit can be placed in an
inactive state by pressing the T/L button three times, until the unit announces “Press HELP to turn off,”
To turn off the Mytrex MXD, unplug the unit from
AC power, remove the phone cord from the unit’s
WALL jack, and hold down the T/L button for
several seconds until the unit shuts down and the
STATUS light goes completely off.

MXD Users Manual

and then holding down the large HELP button on the base unit for three seconds to place the unit in the
inactive state. The STATUS light will go off, indicating that the unit is in an inactive, non-operating
condition. The unit will stay in this state until the unit is unplugged from AC power, at which time the
unit will automatically fully shut down. If the unit is in an inactive state and the “reset”button is
pushed, the unit will return to normal operation mode.
STATUS Light Signals
A single STATUS light is located on the left lower edge of the large
HELP button on the base unit, next to the word “STATUS” printed
on the button (Figure 10). The STATUS light is programmed to
display the following light signals when in normal operating mode:
Steady Green: The MXD is properly plugged in to AC
power and a telephone line, and is ready to call the
monitoring center
Steady Red: THE MXD has been activated by an alarm
signal and is trying to call the response center.
Short Green Flash at periodic intervals: AC power is not
available and the MXD is being powered from its internal
backup battery
Short Red Flash at periodic intervals: The MXD is not
connected to an operating telephone line.
Short Orange Flash at periodic intervals: The MXD is being
powered by its internal backup battery, AND the MXD is not
connected to an operating telephone line. Figure 10. Status Light Detail
When in RANGE TEST mode, The STATUS light will:
Display a red light when it is not receiving a signal from the PHB
Display a green light when it is receiving a signal from the PHB.
Programming a Personal Help Button (PHB)
The MXD unit can be programmed to recognize many PHBs and other devices. These codes are stored in
one or more groups of each type of device. The following table summarizes the groups that have been
made available for each type of device:
Type of Device
Number of Groups

Codes for up to four different PHBs can be programmed into each of the four PHB groups. Each of the
PHBs whose codes are stored within a single group will be treated the same by the response center. This
STATUS

allows a subscriber to have more than one PHB that always is recognized in the same way. For example,
Mary may choose to order two different, including one PHB on a neck lanyard, and other PHB on a wrist
straps. If codes for both of these PHBs were programmed into the first PHB group, both signals would
simply be recognized as Mary's PHB.
Codes for separate PHBs also can be programmed into separate groups so each PHB will cause a different
alarm signal code to be sent to the response center, and the response center will be able to recognize each
PHB as distinct from the other PHB. For example, one PHB might be programmed into Group 1 and
another into Group 2, with one person associated with the PHB in Group 1 and another person associated
with the PHB in Group 2. This is useful in such situations as a husband and wife sharing one unit, where
each person has their own personal information and responder list on file.
To program new PHB codes into PHB GROUP 1, perform the following steps:
1. With the unit turned on, press and release the T/L button on the rear of your MXD base unit. The
base unit will announce, “Range Test Mode.”
2. Press and release the base unit HELP button one time. The base unit will announce, “Program
Personal Help Buttons.”
3. Press and hold down the colored button on the PHB. After about two or three seconds, the unit
will sound a steady tone for about one second, pause for two seconds, then sound the steady tone
for another second. The unit will repeat this tone every three seconds until the button is released.
This is the signal that the unit has recognized and stored the PHB code.
4. After at least one tone is received, stop pressing the PHB.
5. If more than one PHB is to be programmed into Group 1, press and hold the second PHB until the
unit sounds a the tone sequence of one second tone followed by two seconds of silence.
6. Repeat the process for up to a total of four PHBS in Group 1.
7. The MXD can only remember up to four codes in each PHB group. If a PHB is programmed into
a group when there are already four PHB codes stored in that group, the MXD will make room
for the new PHB code by discarding the code already stored in the group for the PHB that has
gone the longest time since the MXD has received the PHB's signal.
8. After four (or fewer if desired) PHB codes have been programmed into a PHB group, press the
Reset button on the back of the unit. The MXD will announce, “System Ready.”This completes
the programming sequence, and each of the PHBs recorded in Group 1 should now be recognized
by the unit.
9. Initiate a test call for each PHB by pushing the PHB and allowing the unit to call the response
center.
10. If each test call is successful, the PHB is ready for service. Reprogram any PHBs that do not
activate the base station when pushed.
To program new PHB codes into PHB Groups 2, 3, or 4, perform the following steps:
1. With the unit turned on, press and release the T/L button on the rear of the MXD base unit. The
base unit will announce, “Range Test Mode.”
2. Press and release the base unit HELP button one time. The base unit will announce, “Program
Personal Help Buttons.”
3. Press and release the base unit HELP button a second time. The base unit will announce,
“Program Personal Help Buttons Group 2.”
4. Program PHB codes into Group 2 by following steps 3 through 6 in the instructions for
programming PHBs into Group 1.

MXD Users Manual

To program a Medication Dispenser Code into the MXD: The MXD unit can be programmed to
recognize up to two Mytrex approved medication dispensers that have been equipped for monitoring by
Mytrex equipment. Perform the following steps:
1. With the unit turned on, press and release the T/L button on the rear of your base unit. The base
unit will announce, “RANGE TEST MODE.”
2. Press and release the base unit HELP button one time. The base unit will announce, “Program
Personal Help Buttons.”
3. Press and release the T/L button again. The base unit will announce, “Program Medication
Dispenser Group 1.”
4. Hold the medication dispenser battery compartment door in one hand. Press and hold the small
button located on the transmitter inside the medication dispenser. After two to three seconds, the
base unit will sound a steady tone for about one second, pause for two seconds, and then sound
the steady tone for another second. The unit will repeat this sequence every three seconds until
the button is released. This is the signal that the unit has been programmed to recognize the
medication dispenser's code.
5. After at least one tone is received, release the button on the medication dispenser transmitter.
If another medication dispenser needs to be programmed to the MXD base unit, push the HELP button
one time. The base unit will announce, “Program Medication Dispenser Group 2.”

dispenser signal, not a PHB signal.
11. If each medication dispenser test is successful, the medication dispenser can be placed in service
in accordance with the dispenser’s instructions.
Provisions for Supervisory Personal Help Buttons, Smoke Detectors and Carbon
Monoxide Monitors (not currently available)
The manufacturer has incorporated code groups for up to eight supervisory devices, eight smoke detectors
and eight carbon monoxide (CO) detectors into the MXD unit. Each group can remember one device

code. These groups are accessed by placing the MXD base unit into RANGE TEST MODE by following
steps 1 through 3 for programming medication dispensers, and then by pressing the T/L button again to
enter in sequence each of the eight smoke detector, eight supervisory PHB, and eight CO detector groups.
Please note that no devices are currently available that are set up to communicate with the MXD
equipment, and the groups for these detectors should skipped for the present time when programming the
MXD to recognize PHBs and medication dispensers. Press the RESET button one time to exit the device
programming mode. When the RESET button is pressed, the unit will return to normal mode and
announce, “System Ready.”
Mytrex MXD Features
Microphone and Speaker
The microphone in your MXD unit is sensitive enough to hear voice communication around corners and
in other rooms of your home. You do not need to be in the same room with the MXD unit for the response
center to hear you! Your MXD unit’s audio system is engineered to provide for an increase of up to 83
times the normal volume.
Two-Way Voice Communication
After connecting to the response center, your MXD unit shifts to a voice communication mode. When in
this mode, the response center attendant switches the MXD base unit between “talk” and “listen” modes.
This greatly increases the coverage and range of clear communication between you and the response
center attendant.
Remote Answering Feature
Your MXD may be used to answer an incoming telephone call. If your phone is ringing and you want to
use this feature, simply push the PHB and the MXD will become active in two-way voice communication
mode. To end the call, simply push the PHB again. Hint: Push the button while the phone is actually
ringing to make sure the calling party is waiting for you to answer the call. Note: In order to ensure that
the phone line is cleared in case you forget to end the call, the MXD will only remain connected for a pre-
set number of minutes, after which the MXD will automatically disconnect the call even if you are still
having a conversation. In the event that you need to send an alarm to your monitoring center while in
remote answer mode, push the PHB to disconnect the call, wait about 10 seconds, and then push your
PHB again to initiate the alarm call.
Inbound calling to the MXD
Your monitoring center and individuals authorized by you may activate your MXD to answer their
inbound calls without your doing anything. To use this feature, the calling party must first be provided
with a four digit code. A calling party with a valid code first calls your telephone number and lets it ring
once, and then disconnects the call. Then the individual waits 20 seconds and calls again. The MXD will
answer the second call after the third ring and send a beep signal. The caller then enters their code and
the MXD will shift to two-way voice mode if the code is valid.
Waterproof PHB
Your PHB may be worn as a necklace, or a bracelet. Both styles are waterproof, and should be worn in
the bathtub and/or shower. Your PHB uses an indicator light to show the status of its internal battery.
While your PHB is being pushed, the light on your PHB flashes green to indicate the internal batteries are
good; a red light indicates the internal batteries may be weak. Every time the response center receives a
signal from your PHB, its battery status is reported. Soft Touch PHBs, which require about half the
pressure to activate, are available. For more information contact your service provider.

Personal Help Button Performance
Your MXD unit is equipped a highly sophisticated radio receiver that is carefully matched to the PHB.
The receiver has very high sensitivity, and interference rejection. The PHB is waterproof and designed
specifically for PERS service. The base unit can receive signals from the PHB from a distance of up
to 600 feet.*
* Your MXD unit is designed to provide for your peace of mind and comfort within the privacy of your
home and yard. The signal from the PHB is limited by various factors, and may vary from home to home.
It is your responsibility to know the effective operating limits of your PHB, and to use it within these
limits. See page 7, step 5 for instructions on how to complete a PHB range test.
Battery Monitoring
Your MXD unit is equipped with an internal rechargeable battery; the battery provides uninterrupted
power to your MXD unit for up to 80 hours if AC power is lost. While the battery powers your MXD
unit, the battery condition is constantly monitored by the MXD unit.
ETL Listed
The Mytrex MXD has been certified by ETL to UL Standards 1637 and 1635, and Canadian CSA
standards for Home Health Care Signaling Equipment. The ETL Listed Mark is proof that your MXD unit
has passed rigorous product safety testing, and has achieved certification.
Remote Programming
Any operational function or parameter can be reprogrammed to customize your MXD unit to your
specific needs, such as dialing “9” to obtain an outside line from your telephone system.
Optional Features
Automatic Voice Test
Subscribers may request the MXD to initiate periodic Automatic Voice Test from their service provider.
Many subscribers feel that these tests provide them with added safety and peace of mind. During an
Automatic Voice Test all critical functions of your MXD unit are tested, including the microphone,
speaker and PHB, to ensure the system is working properly. When the Automatic Voice Test feature is
enabled, the MXD will automatically send an “Automatic Voice Test” message to your response center.
The attendant will greet you, and may ask you to press your PHB, verify your address and phone number,
and ask if any assistance is needed.
Automatic Dial Test
If the Automatic Voice Test is not used, it is strongly recommended that the Automatic Dial Test feature
of your MXD unit be used. This test verifies the ability of your MXD unit to deliver a message to your
response center. When the Automatic Dial Test feature is enabled, your MXD unit will automatically
send an “Automatic Dial Test” message to your response center. If the response center does not receive
an expected test call from your MXD unit, the response center or your service provider may contact you
to help determine the cause.
AC Power Monitoring
Your MXD unit can detect AC Power loss and AC restore, and may be programmed to send automatic
“AC Fail” and/or “AC Restore” messages to the response center.

Medication Dispenser
Your MXD unit, when used in conjunction with a Medication Dispenser, can help manage your daily
medication intake and compliance. When it is time for you to take your medication, the Medication
Dispenser sounds an audible alert. If you do not take your medication in the allotted time, the Medication
Dispenser activates your MXD unit. The response center receives a signal from your MXD unit, and an
attendant will follow the processing protocol as specified by you and your family.
Additional PHBs
Your MXD unit can be programmed to recognize many PHBs simultaneously, either in groups or
individually. Your MXD unit is easily reprogrammed, in your home, to receive the additional PHBs.
Please see “Programming a PHB” instructions on page 14, or contact your service provider.
Audible Alarm
Your MXD unit has an audible alarm that can be silenced for use in applications such as domestic
violence, rape crisis, etc.
*For more information on Optional Features, please contact your service provider.
