Troubleshooting (Q &A)
.
Q. The unit powers up but there is a bleeping from the door station.
A. This means the unit is not able to detect the network for some reason.
-Check the SIM card is activated and has calling credit.
-Power off the unit, remove the SIM and check it in a mobile phone to verify it can make a call.
-Check the SIM does not ask for a PIN code when put in a phone. If it does, then disable the PIN
code request.
-Check the SIM is a standard 2G or 3G SIM. If you are unsure, contact your SIM card provider to
verify. Frequency of operation should be any one of the international quad band standards, GSM
850 / 900 / 1800 / 1900 MHz or WCDMA 800/850/900/1900/2100Mhz
-Check the reception is good. Poor reception is not sufficient.
-Check the antenna has been mounted as high as possible, not near large metal objects, or wet green
shrubs etc.
-Check the antenna connection. Visually inspect that the centre pin inside the antenna is intact, and
has not been pushed back inside the fitting.
Q. The unit calls the first number, but there is not enough time to answer before it diverts to
the next number.
A. Increase the no answer time as per programming instructions.
Q. The unit calls the first number but voicemail comes on before it can ring the second
number.
A. Decrease the no answer time as per programming instructions.
Q. The caller ID part does not work.
A. Be sure to program the caller ID part under 72 feature. If your number is a private or number
withheld, then it will not work.
Even if you have already programmed a number to receive a call from the intercom, if you also
want that number to have caller ID access, it must be programmed under the 72 feature also.
Ensure the number is entered as you would normally dial it from another phone.
Q. There is no audio from the gate, but the person at the gate can hear ok.
A. This can be due to low reception.
-Check reception level by *20#.
-Change SIM card if necessary to another network which may have better coverage.
-Purchase a high gain antenna.
