CLOSED direction to lock it in 
place. 

Do NOT Force or use a 

screwdriver!

Programming Quick Start Guide

Programming is carried out by sending SMS texts to the unit.

3) 

It is recommended to change the “no answer” time if there is more than 1 

number stored. This stops the unit ringing a number after a set time, and can 
be used to prevent voicemail answering the call. Send the following SMS..

The unit can allow up to 100 telephone numbers to be stored, for users to 
be able to ring the system for automatic entry. This uses caller ID like a 
phone to determine the identity of the caller. First, the unit must know what 
country it is operating in. 
4) Program the country code as follows..

GSM-3AB & ABK
GSM-3HB & HBK

2) Program the numbers you wish the unit to dial when the call button is 
pressed, up to a maximum of 3 numbers. Each SMS must start with the pass 
code, default 1234, in the following format *12*1234#, followed immediately 
by a command. E.g to program the telephone number 0987654321, enter 
the following SMS..

tones. If this occurs, check...
1) That the SIM card has been activated and has credit.
2) That the SIM card does not require a PIN code, disable this in a phone.
3) That the SIM card can make and received a call on a phone.
4) If the SIM card was purchased with a phone, that it is not locked to that 
phone. Call the network operator to check.
5) Switch off power, remove and reseat the SIM card and try again.

10) After a final check of 
wiring, switch on the power.
