Programming
Now that you have either entered a new client, or selected an existing client from the client list,
you are now ready to begin programming.
Note: SMS string= *20#
Step1: Check Reception
Go to MORE>INFORMATION to reveal the screen shown.
Press the reception check button. On Android the app will
automatically send a SMS string (*20#) to the intercom.
Due to Android and Apple security, users will be taken to
their SMS screen to confirm the SMS before it will send.
The intercom should reply with a signal level between 1 & 31.
1-12
Poor
13-20
Medium
21-31
Good
For good performance, signal level should be at least 13 or
better on 3G or 4G and 14 or better on 2G.
TIP:
If signal is lower than recommended, then take IMMEDIATE
action. Change network if possible, or use an optional high gain
antenna. Check power cable is within recommended
specification. (Poor power cable can lower reception).

Step2: Set APN (for VOLTE / 4G voice calling)
This feature may need to be set in order to make 4G voice calls. Check
the APN of your provider and then enter it in the blue section below and
send as SMS to the intercom

Step3: Reboot the Intercom
The intercom will need to be rebooted in order to log on to the network with the new APN which
you have stored. If you send another reception check (*20#), you may find that if it was on 3G
signal strength before, that it is now on 4G signal.
