7. General Descriptions
This product is to be used to monitor the customer’s property. In case of alarm, its primary task is in informing the customer of it as quickly as
possible by text message. Scaring off by an alarm sound is an addition option that must be configured. Vibrations can be monitored, living beings
recognised with the integrated motion detector and noises determined. In case of alarm, the GX103+GPS sends an alarm text message to up to
6 saved phone number and is able to call back a phone number afterwards(optionally with the speaker deactivated, silent mode).
The customer may at any time perform other actions by sending text message from his mobile phone, e.g. determine the current GPS position
(coordination or web link), request the status, or perform a “silent call” to hear what is currently taking place in the monitored area.
The microphone or speaker can be used to accept calls and call pre-set phone numbers.
The update function can be used to give the device new functions that Conrad Electronic provides in the scope of product improvements.
The GPS receiver is used to determine and monitor GPS zones (Area, GeoFence), i.e. places where the product may be present.
The product is secured against manipulation with an internal battery.
This product is not a common phone. The sensors and GPS function increase the functional scope and thus also complexity. In the
following, the most important items that you should observe when using the product are noted.
These instructions assume the functional scope at the time of initial delivery. The option of the firmware update may add new functions
via the USB interface. Visit the website on this product from time to time on our website www.conrad.com, where you may find new
firmware and revised operating instructions.
All text message answer examples are to be understood symbolically. Actual implementation may vary. The examples should only
show the information to be expected, their format and writing.

GSM LED (5):
This LED shows the current GSM status. For this, the LED has the following presentation options:
• LED is lit green = Searching for GSM network
• LED flashes green (every 1 s) = Device registered at the GSM network
• LED flashes green (every 1/2 s) = call / phone connection
• LED flashes red/green = no GSM network connection / PIN error / invalid SIM card / PUK / …
• LED off = no power supply present / product off
When the product is charged via the USB socket without any SIM card inserted, the green LED is displayed. Since this LED is
controlled right by the GSM module and the GSM module was switched off entirely (switch in the SIM card holder), this LED may be
lit by accident. Without SIM card, the GSM module is definitely off and will not try to log on to the GSM network.
Battery LED (4):
The internal battery is charged and managed via a separate hardware. Thus, the battery can also be charged when no SIM card is inserted and
the entire GSM hardware is deactivated. This LED provides the following information:
• LED is lit red: The battery is being charged
• LED is lit green: The battery is charged completely
• LED is lit orange (red and green at once): An error was recognised (e.g. no battery present)
• LED off = no USB voltage present
GPS status LED (1):
This LED is used to recognise the activity and status of the GPS receiver. The following display options are available for this:
• LED flashes blue: Current GPS position determined correctly
• LED is lit blue: GPS position not determined or determinable
• LED off: GPS module is in sleeper mode / switched off
The GPS receiver is on the front, right below the GPS-LED.
Important note on accuracy of GPS positions:
Accuracy of the GPS position determined depends on many factors. Since the GX103+GPS leaves the GPS receiver off at all times
for runtime reasons in battery-powered operation, this will negatively influence accuracy. The GPS signal as such is overlaid by
correction data that are saved in the device and will accelerate, among others, satellite search. Therefore, we recommend that the
product is left to assess the GPS positions for a few minutes if there are any problems with accuracy. This procedure is called
“tracking”. It should reduce the deviation to regular GPS accuracy. For this, observe the description on the command “TRACK”
LEDs in the buttons “1”, “2” and “3” (8/9/10):
These LEDs have various functions. The primary task is showing the current status behind the function that was linked to the corresponding
button.
If, e.g., the motion detection was configured behind button “1” (“MOVE”), pushing this button will activate the alarm sensor with its last settings
(can be recognised by the activated LED). Another push of the button will switch off this function and therefore the LED again.
Since the buttons have different functions in the “CALL” mode, the function described above only applies in regular mode (in which the alarm is
deactivated).

8
Left button (6):
This button switches the alarm mode of the product. The change is triggered only after pushing and holding the button for a few seconds.
Depending on configuration (see function description on the command “COUNTDOWN”), a countdown signal is generated upon activation to
give the user some time to leave the sensor range. After an alarm incident is recognised, there will be a waiting time of some seconds to enable
the user to switch it off.
Right button (7):
This switches the device on or off. The reaction to pushing a button takes place only after pushing and holding it for a few seconds.
Button 1, 2, 3 (8/9/10):
These buttons have no function in the “ALARM ENABLE” mode.
In regular condition, these buttons can be set freely. The functions these buttons can be assigned are shown in the chapter on the function
description for the “KEY” command. For example, a phone number to be called can be stored on these buttons, or they can be used to switch the
sensor on and off.
The buttons have the following functions during a phone call:
• The button “1” (8) serves to hand up or reject a phone call.
• Use the button “2” (9) activates and deactivates the speaker.
• Use the button “3” (10) accepts a call. The product can only be called when this was set accordingly in the “INCALL” command.
USB socket (14):
This USB socket is used to load the product. No SIM card is required for this. Additionally, permanent operation via USB is intended. Connected
to the PC, a driver is needed for the “virtual COM port” so that the product can be configured via USB and a firmware update performed. The
required software and firmware files are available online at www.conrad.com, in the download section for the product.
Use of the product with another software than the one released there officially is not intended and may limit the warranty/guarantee.
Additional safety notes apply for firmware updates. They are displayed briefly before execution in the firmware update software.
Permanent operation using a USB po0wer supply is intended but not possible right at the PC. The USB bridge chip internally shares the same
port as the GPS receiver; therefore, the GPS receiver will not work wile the device communicates with the PC. Therefore, use of the external
USB mains adapter is recommended.
Speaker (2) and microphone (11):
The installed speaker also serves to play back alarm and ring tomes and hands-free function. Two microphones are installed. The first microphone
is needed for talking and directly connected to the GSM module. The second microphone is used for sound level measurement and issues an
alarm when the alarm threshold value set (sound level) is exceeded. The two microphones are located next to each other in the same position.
Extension port (13):
This 2.5 mm jack socket serves to later expand the product with various accessories. For more information on this, see the product website at
www.conrad.com.
No headset, headphones or other devices with jack plug must be connected to this jack socket. There is a danger of the irreparable
damage to the product and the connected device.

b) Product Status and Mode
The product has the following modes:
“Alarm Enable”:
This mode is entered by the text message command “ALARM ENABLE”, pushing and holding the left button and, depending on configuration,
e.g. via a call. Whether or not the alarm is active can only be seen by a status text message.
Only in this mode can the product send text messages independently and without any customer interaction, and perform a recall - depending on
configuration. This only takes place when an activated alarm source recognises an alarm incident (vibration, PIR, microphone, etc.). Only in this
case, all phone numbers in the device phonebook (not that of the SIM card) will receive the corresponding alarm text message.
“Alarm Disable” (regular mode):
This mode is also designated the “regular mode” that is entered after the product is switched on. In this mode, GSM costs may only arise when
customer interaction triggers it. The product only sends out text messages when a text message with the correct PIN was received first. The
device will only call on direct command anymore (button,...) from the customer. The product then also cannot trigger an alarm.
Call (incoming):
The product’s reaction to an incoming call is defined by the function “INCALL”. The basic setting is rejecting the call to save energy. To be able
to use the product as a phone, for example, the “INCALL” function must be set in the mode “CALL”. For more information on this, see the
corresponding chapter.
USB connection:
While a USB connection is active (i.e. with data communication to the PC), the GPS-receiver cannot be used.
For a passive USB-connection, in contrast (e.g. when connecting the device to a USB mains adapter), the GPS receiver remains active at all
times. The remaining functions are not affected by any USB connection.
c) Notes on Use
• There is no prescribed usage position.
• When using the USB or jack socket, observe that there is enough place for the plugs. Lateral forces on the plugged-in plugs can lever the
sockets from the PCB and thus cause irreparable damage, loss of warranty/guarantee!
• To ensure the device function, choose a usage site where the GMS network reception is as good as possible.
• The setup site should be protected against overheating of the device, excessive moisture and dust.
• The product should be taken to a site where object vibration can be measured (for use of the vibration alarm).
• The product must not be subject to continuous strong vibrations (vibrating machines, direct motor/chassis contact).
• The product is not protected against weather and therefore must be installed inside.
d) Firmware Update
A firmware update is performed via the USB interface at a PC with Windows operating system. For this, the PC software for the product is
needed that can be found in the download area for the product at www.conrad.com.
• New firmware versions are a voluntary service by Conrad Electronic SE and its partners and mainly serve product maintenance. There is no
legal claim to this.
• Performance of a firmware update is connected to a certain risk. If the transmission is interfered with during the update process, this may
cause the module to no longer function (including update function). In this case, the customer must return the product to the customer service
with the note “FULL FIRMWARE UPDATE”. The costs for a firmware update must be assumed by the customer. Whether any costs arise and
how high they are is indicated in a previous cost estimate.

10
e) Notes on the Electrical Connection
• The external cables must be kept as short as possible and remaining line lengths must not be coiled.
• Too-strong temperature fluctuations may lead to temporary impairment and require manual reset in extreme cases.
• The product is not intended for the “Safety” area and also does not correspond to any SIL/ASIL level.
9. Commissioning - First Steps
The following is needed for operation and configuration of the device:
• A common mobile phone with SIM card
• An additional SIM card (prepaid or contract) for the device
• A USB port (PC, or included USB mains adapter)
a) Operating Voltage
The product should be connected to the USB mains adapter for testing. The battery LED shows whether the operating voltage was connected
correctly, no matter the device status:
LED off = no external voltage supply present
LED is lit green/red/orange = external voltage supply present
An unloaded battery in combination with bad GSM reception may lead to the module having to switch off in spite of USB connection
to protect the internal battery against deep discharge. If such behaviour occurs during the test, wait for a few minutes until the battery
was sufficiently loaded to be able to deliver the energy for the GSM module.
The GPS receiver is deactivated ruing a connection to a PC. When this function is required, connect the device to the USB mains
adapter rather than the USB port of a PC.
GPS reception in building sis only possible when the device is placed right by the window, so that there is a free view of the sky and
therefore the GPS satellites.
b) Changing the PIN Code to “1513”
Every SIM card has a PIN code. Because this GSM product uses its own PIN processing, the SIM card PIN code must be changed to that of the
product.
The following steps are required for this:
• The SIM card intended for the product must be inserted in any mobile phone.
• According to the operating instructions of the mobile phone, the PIN code must be changed to “1513”.
• The SIM card with the changed PIN code must be removed from the mobile phone.
• The SIM card with the changed PIN code can now be inserted in the intended device slot (see next chapter).

11
c) SIM Card Insertion
• The SIM card with the PIN number “1513” must be inserted in the device as shown in the following.
• When the SIM card is inserted, the product is still switched off. To switch it on, push the “On/off”
button (7) for a few seconds until the GSM LED lights up. First, the GSM LED is lit green (GSM
network search); after a few seconds, the LED should start flashing (GSM network found, device
ready for operation).
If the green LED does not start to flash, there is no connection to the GSM network. In this case,
the network quality and function of the SIM card must be inspected at the product site with a
separate mobile phone.
If the LED flashes red, there is an error when connecting to the GSM provider or the PIN number
is incorrect. In this case, the device must be reset to factory settings. Furthermore, the SIM card
(PIN/PUK/activation) must be inspected and the receiver quality at the device position must be
verified with a separate mobile phone.
• If the device used to be used with another SIM card, there is the option of the PIN number in the
product being changed and now no longer matching the default setting “1513”. In this case, reset
the device to factory settings (section “Factory Reset”) and manually set the SIM card PIN in your
mobile phone to “1513”.
• The SIM card may have been locked in the meantime and must be unlocked with the PUK.

12
10. Configuration via Text Message
a) General Information
To receive the full functional scope of the product, it must be configured first. The entire configuration is performed by simple text message
commands you send to the device (the phone number of the SIM card in the device) from your mobile phone.
This method makes it possible to activate, deactivate or change the settings of your device from anywhere.
Alternatively, the product can be configured via the USB interface using PC software.
These operating instructions do not deal with the PC software configuration. This only describes how the product can be controlled
with a mobile phone only, without any other aids.
To protect from unauthorised access, the product generally reacts to authenticated messages only. In a text message, you authenticate
yourself by including the correct PIN number (not the one of the mobile phone from which the text message was written).
When calling, the conveyed phone number must correspond to a phone number in the phone book.
Caution, important!
For your own safety, the PIN number must be changed under all circumstances after commissioning of the product. This is
described in more detail in the chapter corresponding to the command.
Introduction to the Command Format:
The text message to programme the device is set up according to the following chart, observe the examples:
<ACTION> <FUNCTION> <PARAMETER1> <…> <#PIN>
SET TEL1 [phone] #1513 (phone book)
RESET INCALL #1513 (no calls)
TEST IN1 #1513 (request IN1)
Important!
Every text message sent to the device must end with the PIN set as protection. Without “#PIN” at the end of the text message, it is
discarded and no answering text message will be generated!
The individual words and parameters must be separated by a space each.
<ACTION>:
The following action can be determined:
SET = switch on/activate/configure
RESET = switch off/deactivate/default settings
TEST = test/check/request
<FUNCTION>:
This is used to select the function you want to change or perform:
TEL1 = phone book entry no. 1
Name = Device name
INCALL = Setting for incoming call
<PARAMETER>:
Both the presence and the number of parameters depend on the function and action used. Therefore, most “RESET” actions have no parameters
while “SET” actions (what should be set to which value) without any parameters are rather rare.

13
A parameter may be the following:
List: The customer may choose a parameter from a pre-defined list, e.g.: DE, EN, LH, HL, LHL,…
Writing: <DE/EN>, <LH/HL/LHL/..>
Number: An integer without decimal digits, optionally with prefix, e.g.: 5 = time [sec.] (SET IN1 LH 5 #1513)
Writing: <TIME>
TIME = xxx to xxx, xxx = ….
Examples: (if the PIN of the device “ is 1513):
SET INCALL CALL #1513 Callers are admitted (observe phone book)
SET MOVE 5 #1513 Activation motion detector with medium sensitivity.
Note on the RESET command:
If a function is to be switched off or reset due to an error, the corresponding “RESET” action must be used with the corresponding function word!
This action is universally applicable for all functions/text message commands and resets the corresponding function to the default value.
Example:
RESET INCALL #1513 All incoming calls are rejected.
Capitalisation is not relevant; you may use capital and small letters as you wish.
Every new command of the same function (2nd word) will overwrite the previous settings.
After every text message command, the device will return a test message answer to confirm the programming (if the PIN in the text
message command was correct and the phone number is conveyed).
b) Special Commands
There are commands that are so important that they deviate from the command format from the previous chapter on purpose. These commands
are:
ALARM ENABLE #1513
ALARM ENABLE #1513
This command is used to switch the alarm mode on or off. The effects this has on the product behaviour were already described in the
corresponding chapter 8. b) “Status and Mode”.
STATUS #1513
This command returns a summary of the most important settings and conditions of the device.
Example (deviations possible depending on firmware version):
Answer:
GX103_GPS 1.08 Product name, firmware version
Alarm: off Alarm deactivated (function “DISABLE”)
Batt: 100% Status of the rechargeable battery
GSM: 59% GSM signal strength
GPS: on Status GPS receiver
Area: off Zone monitoring / GeoFence (function “AREA”) off
Move: off Motion detector off
Shock: off Acceleration sensor off
Voice: off Microphone monitoring off
USB: off Status Voltage monitoring off

11. Functional Descriptions
In the following examples, it is assumed that the PIN of the SIM card in the device is “1513”.
a) General Configuration Commands
1. Changing the PIN Code (Command “PIN”)
To secure the product from unauthorised access, the standard PIN “1513” may be set to any other value. Change the PIN code as follows:
SET PIN <new PIN> #<old PIN>
Example: Changing old PIN 1513 to new PIN 1234:
SET PIN 1234 #1513
For every new text message command, the new PIN code now has to be appended preceded by a (#) sign. If the wrong PIN code is entered or
the PIN code is not sent, you will not receive an answering text message.
Changing of the PIN code will change both the settings of the product and the PIN code of the SIM card! The PIN code always has 4 figures.
When the PIN code is lost (lost or forgotten), the product can be reset to factory settings (see chapter “Factory Settings”). All programming will
be lost when resetting! Then the device must be programmed again. Resetting the device to factory settings will not affect the SIM card. The SIM
card PIN is retained.
2. Changing the Device Name (Command “NAME”)
If several products are operated at the same time, it is recommended to assign a different name to each device. This makes it possible to assign
alarm messages to the correct device.
The device name has a maximum length of 15 characters. Do not use any spaces or special characters.
To change the name at your device, send the following text message command:
SET NAME <new name> #1513
Example: Renaming to “NEWNAME”:
SET NAME NEWNAME #1513
Confirmation text message:
NEWNAME 1.xx
...
...
Factory reset:
RESET NAME #1513
There is no TEST action for this function.

15
3. Setting the language (Command “LANGUAGE”)
This command sets the product langauge.
SET LANGUAGE <DE/EN> #1513
Example:
SET LANGUAGE DE #1513
This command is needed to reset to German:
RESET LANGUAGE #1513
There is no TEST command for this command.
4. Setting Time and Date (Command “TIME”)
The product offers time and date settings. This way, the precise time and date at which the text message was generated is stored in the text
message, independently of when the text message was sent or received. Various functions also require the current time and date.
SET TIME <hh mm dd mm yy> #1513
Hour Minute Day Month Year
(0-23) (0-60) (1-31) (1-12) (0-95)
Example:18:22 hours, 24.03.2012
SET TIME 18 22 02 04 12 #1513 time
Example of a text message response:
GX103_GPS 1.08
Time: 18:22
Date: 02.04.12 Mo
GPS: on
Status: off
Protective time: not specified
Alarm every 7 min
GPS: 60 min
Alarm en. delay: 15s
Alarm delay: 0s
To check the current time, use the following command:
TEST TIME #1513
There is no RESET function for this command.

5. Administration of Phone Book (Command “TEL”)
Up to 6 phone numbers can be programmed into the device. In case of alarm, a notification text message is sent to each of these phone
numbers. Additionally, only these phone numbers are accepted for the INCALL function.
If the same number is in the list several times, it will receive the same text message as many times.
The product generally can only process phone numbers in the international format:
Example: Phone number 0177/12131415 = international: [phone]
Sending text message commands to the product:
SET TEL1 +49111… #1513
SET TEL2 +49222… #1513
…
SET TEL6 +49666… #1513
There is the option of programming several phone numbers in a single command.
Example for 3 phone numbers (TEL1 to TEL3):
SET TEL1 +49111… +49222… + 49333… #1513
After sending the command “SET TEL....”, a text message answer with a list of saved phone numbers is generated:
GX103_GPS 1.08
———————

SMS1
+49111
SMS2
+49222
SMS3
+49333
SMS4

Phone areas (only affects function “INCALL”):
There is the option of defining phone number ranges that are permitted for the INCALL function. Use the normal “SET TEL” command with the
placeholders; see the following example.
The following numbers are to be released for “INCALL”:
[phone]
[phone]
[phone]
The following phone number must be programmed:
+4915555*****
The asterisks (*) are placeholders for any number.
The corresponding number of placeholders (*) must be inserted. The calling phone number is compared to these place holders. If the
calling number is longer or shorter than placeholders available, the number will be rejected.
Please observe that all other phone number combinations are permitted! You accept this risk when using this function.

17
Deleting the phone numbers saved
To delete a phone number, you need the following commands:
Example: Deleting the 1st and 3rd number
RESET TEL1 #1513
RESET TEL3 #1513
To delete all phone numbers:
RESET TELALL #1513
After sending the command “RESET TEL....”, you will receive a text message answer.
Testing phone number
To check the phone numbers stored in the product, you may use the following command:
TEST TEL #1513
Always enter the complete phone number in international format (including country code), e.g. +49… for Germany. The text message commands
(TEL1, TEL2, TEL3,…) change only the phone number of the corresponding memory. The numbers of the other memory are retained.
6. Alarm Sound at Alarm (Command “ALARMSOUND”)
Due to the small size of the product, it may be of disadvantage that the product draws attention by an alarm sound. The unauthorised person
would be able to destroy the product to prevent notification. Therefore, the alarm sound can be adjusted. The product may therefore inform the
customer secretly that something is happening, permitting additional actions.
The alarm sound can be set as follows:
SET ALARMSOUND <Alarm position> <Alarm length> #1513
Position: 0 = no alarm
1 = after text message dispatch
2 = at once
Length: 1 to 255 s
Example:
Deactivation of alarm sound:
SET ALARMSOUND 0 255 #1513
Activation of alarm sound for 30 s after all text messages were sent:
SET ALARMSOUND 1 30 #1513
The current status can be determined with the following command:
TEST ALARMSOUND #1513
To return to the default settings (30 s), use the following command:
RESET ALARMSOUND #1513
Activation of the alarm sound may impair the “RECALL” function. You will mainly hear the active alarm sound.

7. Speaker Events (Command “SOUNDINFO”)
During the setup phase, it may be of benefit to hear what the product does right now. In may places of the firmware, sound outputs are stored that
indicate an event. By default, these sounds are deactivated so that the module will not give itself away during surveillance.
The sounds can be activated with the following command:
SET SOUNDINFO #1513
Deactivation of the sounds is possible with the following command:
RESET SOUNDINFO #1513
There is no request option for this (command “TEST”).
8. Changing the Calling Sound and Volume Settings (Command “AUDIO”)
The device has different audio components like speakers, microphone and remote control. The audio settings are set in the default settings on
level 5.
This setting can be changed in a range of 0 (lowest stage) to 9 (highest stage). The following command must be used for this:
SET AUDIO <SPK> <MIC> <MELODY> <RING Vol> #PIN
<SPK> = speakers: 0 (low) .........9 (loud)
This changes the speaker volume when a call is received while “INCALL” is in the CALL mode.
<MIC> = Microphone: 0 (insensitive)..........9 (sensitive)
This changes the microphone sensitivity during a call (INCALL, SILENTCALL, RECALL, …).
<RING> = ring tone 0 (low).........9 (loud)
This changes the ring tone volume when a call is received while “INCALL” is in the CALL mode.
<MELODY> = ring tone melodies
There are the following ring tone melodies: 0 = Grieg (Peer Gynt)
1 = Beethoven (Ode to Joy)
2 = Beethoven (For Elize)
3 = Mozart
4 = Bizet (Carmen)
5 = Rossini (Wilhelm Tell)
6 = Quick buzzing
7 = Default tone
8 = Short buzzing 1
9 = Short buzzing 2
Reset to factory settings:
RESET AUDIO #1513
Checking settings:
TEST AUDIO #1513

9. Time Setting Alarm Activation/Deactivation (Command “COUNTDOWN”)
The alarm function is also changed, e.g. directly at the device using the left button. However, you are in sensor range for the condition change
(“ALARM ENABLE” to “ALARM DISABLE”) when the button is used for the change. To give the user some time to leave the sensor range, there
are two countdown timers that are set as follows:
SET COUNTDOWN <Time_Enable> <Time_Disable> #1513
Timer <Time_Enable>:
The countdown is started after the alarm mode is activated (“ALARM ENABLE”).Acountdown beep sounds. When it ends, the product is armed.
A time can be set from 1 - 60 s.
Timer <Time_disable>:
If an alarm is triggered in the active alarm mode (“ALARM ENABLE”) (e.g. by motion detector), you can order the device to delay triggering the
alarm for a certain time (text message, call, alarm tone). This gives the customer the time to switch off the product with the left button.
A time can be set from 1 - 120 s.
The current times are determined with the following command:
TEST COUNTDOWN #1513
To reset the values to default (Timer <Time enable> = 15 s, Timer <Time disable> = 1 s), use this command:
RESET COUNTDOWN #1513
The mode refers to condition change by the left button only. Text message and INCALL deactivate the alarm at once.

b) In- and Outputs
This is an autonomously working alarm reporting device. Wrong settings or connections can cause undesired txt messages to be sent
and possibly high costs!
Never enter the phone number that belongs to the SIM card that is inserted in the module!
Also never enter any phone numbers from any other GSM alarm systems or GSM reporting devices!
1. Configuration of the Sensors (Commands “SHOCK”, “MOVE”, “VOICE”)
The product has various sensors like vibration sensor, motion sensor (PIR) and sound level monitoring. The vibration sensor reacts to mechanic
vibration, such as parking impact, broken windows, etc. The motion sensor can be used to monitor a hallway, entrance door or garage door. The
microphone can be used to monitor, e.g. a room or area.
Every sensor’s sensitivity can be set. The best sensitivity settings depend on many factors such as installation site, car body connection, object
size, etc. and must be found individually by testing.
Configuration command:
SET SHOCK <sensitivity> #1513
SET MOVE <sensitivity> #1513
SET VOICE <sensitivity> #1513
Sensitivity: 0 = Off
10 = maximum sensitivity
Factory reset (off):
RESET SHOCK #1513
RESET MOVE #1513
RESET VOICE #1513
Determined current settings:
TEST SHOCK #1513
TEST MOVE #1513
TEST VOICE #1513
If the sensitivity is set too high, undesired text message alarms may result, depending on application case. There are provisions to
prevent high costs (“IDLEALARM”), but they may still result in some individual cases. Conrad Electronic assumes no liability for
defectively set or programmed devices.
For best setting, we recommend the command “DIAGNOSE”.
