POWER SOURCE This unit should only be connected to a 110-120 VAC
power source as marked on the unit.
☞
GROUNDING OR POLARIZATION This unit is equipped with a polarized
AC power cord plug (a plug having one blade wider than the other). This
plug will fit into the power outlet only one way. This is a safety feature. If
you are unable to insert the plug fully into the outlet, try reversing the plug.
If the plug still fails to fit, contact your electrician to have a suitable outlet
installed. Do not defeat the safety purpose of the polarized plug.

NON-USE PERIODS Always turn the unit off and unplug when it is not being
used or left unattended for long periods of time.
☞
OBJECT AND LIQUID ENTRY Never push objects of any kind into the unit
through the cabinet slots as they may touch dangerous voltage points or
short out parts that could result in a fire or electric shock. Never spill liquid
of any kind on the unit.

NOTE:
“WIRELESS TECHNOLOGY” can infer sound transmission is
carried on the airwaves or through the electrical wiring of your home or
business. Linear Wireless Intercom Products have sound carried on the
electrical wiring. The wiring in your building must be able to complete an
electrical loop without any interference. This means that the electrical line
coming from the transformer outside your building, will enter your building,
loop through each roomand exit at the same point where it entered. If there
has been an added loop brought in, remodeling done, or a sub-transformer
is present, transmission may not be possible.

CONTENTS
Thank you for your purchase of the Linear Doorbell Intercom Security
System. Linear is proud to bring to the public an easy-to-install and use
in-home security and communications system. By using your home’s
electrical wiring to carry sound, the Doorbell Intercom Security System
offers you the opportunity to answer the door from any electrical outlet
on your property.* In addition to the convenience that this product
brings, you will also appreciate the security feature, that makes it
possible to talk to people outside your door, without actually opening it.
*This occurs if all outlets around the property are connected to the same
electrical loop that the household wiring is on. Most homes in the U.S.
will have only one electrical loop on the property.

INTERCOM INSTALLATION
1. Choose where you want to plug in the
wireless intercom that is being used as
a doorbell. Make sure that the channel
selector on each of the intercoms you
install are on the same channel as the
doorbell module. We recommend that
you dedicate at least one intercom per
floor. (Do not change the channel
position on dedicated intercoms after
you have installed the system).
2. Locate the volume control screw on the
backofthedoorbellmodule.Useasmall
Phillips-head screwdriver to raise or
lowervolume.Toincreasethevolumeof
doorbell module, turn screw counter
clockwise.
TESTING THE SYSTEM
Make sure doorbell module AC adapter is plugged in and that Wireless
Intercom is plugged in. You should see light shining through both
buttons on the front of the doorbell module. This indicates power is
present.
1.
Ask someone to assist you. One person should stand at door,
while second person stands next to the Intercom.
2.
Person at door should press DOORBELL button. This should
produce a doorbell sound.
3.
Person at intercom should now press and hold down TALK
button and speak to the person at doorbell. Then release to wait
for reply.
4.
The person at door should now press TALK and answer back.
5.
To continue conversation, simply press TALK button back and
forth between the two locations, remembering to release the
buttons when waiting for a reply.
6.
If the sound is good, you may now replace the retaining screw.
The LOCK and CALL buttons on the wireless intercom have no practical
use in the doorbell application. They are used only when communicating
between two or more wireless intercoms. You may purchase additional
wireless intercoms to create an in-home communication system. You
would use whatever channel or channels that have not been assigned
to the Doorbell Intercom Security System. Remember that the wireless
intercoms assigned to the Doorbell Intercom System are dedicated and
should not be used for any other purpose.

TROUBLESHOOTING
No Sound ☞Check to see if channel selection is the same on doorbell
module and wireless intercom.
☞Make sure LOCK button on wireless intercom is up.
☞Make sure wireless intercom is turned on and volume control
is up.
☞Makesurevolumecontrolonbackofdoorbellmoduleisturned
up.
☞Make sure the light shines through on both buttons on front of
doorbell module, if the lights are not there, this means
electricity is not reaching the module. Check to see if wires
connecting doorbell module and AC adapter are firmly
connected. Make sure that AC adapter is plugged into outlet
and that there is electricity at outlet.
☞You may have damaged wire connecting the doorbell module
and AC adapter. Reconnect doorbell module and AC adapter
with good wire.
☞You may have more than one electrical loop. Try moving
wireless intercom to other outlets around your home to see if
any connect with the electrical line the adapter is plugged into.
If all of the above have been tried withoutsuccess, disconnect
adapter and doorbell module and reconnect with a few feet of
wire. Plug adapter into an outlet and plug wireless intercom
into same outlet. If both units are on the same channel, but do
not communicate, call the telephone number on the enclosed
warranty card.
Poor Sound Quality
☞Fluorescent lights, computers, base units of cordless phones
and touch-activated appliances may cause a scratchy or
broken signal. The strength of Linear filters is superior to most
other intercoms; however, modern consumers are adding
more technologically advanced products to their household
current, some of these products may cause electrical
interference. Please try the following steps to determine if
improvement is possible.
1.
Change channel on back of doorbell module and on
wireless intercom.
2.
Plug wireless intercom into different outlets around the
property.
3.
You may have a loose connection. Check all terminals
and wire.
