Checking Signal Level and APN
When the green and white status LEDs (shown on previous page) flash to indicate network
connection, the SMS string
*20#
can be sent to the intercom to check the signal level and
APN.
Check Signal Level:
The intercom should then reply with a signal level between 1 and 31.
1-12
Poor
13-20
Medium
21-31
Good
For optimal performance, the minimum signal level required is 13 on 4G systems.
Check APN Setting (required for VOLTE / 4G services):
The intercom is designed to obtain the APN dynamically i.e. automatically apply it. (If you do not
get a GREEN LED on the PCB after a maximum 180 seconds then you may need to apply the
APN manually).
Ensure the correct APN is being used for long term connection:
(a) Ensure the APN* information is correct for the SIM card in use.
(If the SIM is provided by AES the APN should be ‘
RESELLER
’.)
*You can obtain the correct APN to be used by contacting the SIM card supplier.
(b) If the APN is incorrect, you can reset this by sending the below SMS string.
9999#97X#
(replace X with the APN provided by the SIM supplier. E.g. 9999#97RESELLER#)
(c) If there is no 2G/3G signal in your area the system will not be able to connect to the
network at all without applying the APN.
If you purchased a unit with keypad you can contact technical support for the correct APN serial
code that matches the APN for the network being used, then follow the process below:
1. Press and hold the call button before turning the unit on.
2. Upon power up, a long tone will be emitted from the speaker and the blue LED will remain solid
- it is now in the APN setting mode.
3. After this, enter the APN serial number through the keypad then press #. (e.g. if you want to set
APN No. 18, press 1 - 8, then #. A long beep will again be heard)
4. Reboot unit.
If the MMS Settings (*30#) are not correct or not present after setting the APN, then this
information will need programmed separately via the app. (The Cellular Module is pre-
loaded with an APN/MMS Settings whitelist. Setting an APN from this list will auto-fill the
MMS Settings required for a visitor to receive an MMS when the push button is pressed).
