Troubleshooting
Q. The unit will not power up. No LEDs on.
A. Check power supply voltage at intercom is 23.4v DC or more. Cable length from PSU to
intercom should be less than 25 feet and in 14 gauge for longer distances. See guide. Check the
fuse.
Q. The unit powers up but is not showing network reception or will not respond to SMS .
(No green CPU light).
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 if it is a Pay As You Go SIM.
-Disable any PIN code request if active on the SIM card.
-Check the SIM is a standard voice capable SIM. If you are unsure, contact your SIM card
provider to verify.
-Check the reception is medium or good. Poor reception is not sufficient.
-Power off, remove the SIM, use fine sandpaper to lightly sand the SIM pads and try again.
-Check antenna is connected and does not have too many sharp bends on the antenna cable.
-Check the height of the antenna and make sure it is not inside a metal enclosure.
- Check correct power cable size for cable length from PSU. Refer to manual for guidelines
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 function does not work.
A. If your number is private or number withheld, then it will not work.
-Ensure the number is entered as you would normally dial it from another phone.
-For International customers, ensure the numbers have been entered with their international
dialling code. If this does not work, try again without.
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#.
-Change SIM card if necessary, to another network that may have better coverage.
-Purchase a high gain antenna.
This may also be caused by a defective microphone, water on a microphone from a sprinkler for
example, or dirt/insects blocking the microphone hole. If reception is optimum and the problem
persists, contact your supplier or installer.
