The intercom SIM card will need topped up occasionally if it is a pre-pay casual SIM card. It is
recommended that you register this SIM card on the provider's web site. You can register card
payment details. Many networks offer an auto top up feature, which means they will automatically
top up your intercom when the balance runs low.
The stainless steel can dull or discolour over time in weather conditions. This can be polished with
a suitable stainless steel cleaner.
Troubleshooting guide
Q. The unit will not power up. No LEDs on.
A. Check power supply voltage at intercom is within 14.5v-15v DC. Cable length from PSU to
intercom should be less than 15 feet.
Q. The unit powers up but is not showing network reception or will not respond to SMS.
A. This means the unit is not able to detect the network for some reason.
-Power off the unit, remove the SIM and check it in a mobile phone to verify it can make a call and
has calling credit.
-Disable any PIN code request if active on the SIM card.
-Check the SIM is a standard voice 2G capable SIM. If you are unsure, contact your SIM card
provider to verify. Frequency of operation should be any one of international quad band
standards, 850 / 900 / 1800 / 1900 MHz.
-Check the reception is good. Poor reception is not sufficient.
-Check that the cable from power supply to intercom is less than 15 feet and that the cable
thickness is 1.5mm or 14 gauge if longer than 15 feet. Alarm or CAT5 cable is not sufficient.
-Power off, remove the SIM, use fine sand paper to lightly sand the SIM pads and contacts on the
GSM unit, lightly bend the contacts upwards so that they make better contact with the SIM and try
again.
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 or excessively long power cables.
-Check reception level by *20#.
