-Change SIM card if necessary to another network which may have better coverage.
-Purchase a high gain antenna.
-Increase height of antenna.
This may also be caused by a defective microphone, water on a microphone from a sprinkler for
example, or dirt blocking the microphone hole. If reception is optimum and the problem persists,
contact your supplier or installer.
Q. The audio quality that can be heard on the remote telephone is poor or humming
(buzzing).
A. A small amount of GSM buzz can be considered normal on GSM intercoms, but not so much
that causes inability to hear the person speaking. This can be caused by the GSM antenna being
mounted too close to the speech panel or not mounted high enough, or poor power cables being
too long or thin.
-Try earthling the speech panel chassis to 0V of the power supply.
-This is also a symptom of poor reception. Try above steps on checking and improving reception.
Q. The keys do not work when the intercom calls a phone.
A. Check if you can hear the relay clicking at the gate when the keys are pressed during a call. If it
can be heard, then the system is working, check wiring between the relay and the lock or gate
panel. If the relays do not make a clicking sound, then check this feature on a different mobile cell
phone or landline. If it works on a different phone, check the settings on the phone in question
under DTMF tones.
Failure of DTMF tones to operate correctly is also a symptom of low reception or insufficient
power cabling. Check steps above on improving reception or addressing the power problem.
-Some iphone users may experience trouble using the * key to trigger the gates. In this case, refer
to your distributor on how to change the trigger key to any other key. Also check that the relays
are not already latched with the *22# command. If they are latched, they need unlatched before
the trigger keys will work.
Q. The keypad confirmation bleeps when I enter my code but the gates or door lock does
not open.
A. Check wiring. The keypad relay should be connected to the lock or gate system as well as the
relay inside the GSM cellular part of the intercom.
- Do not wire power to the intercom in alarm cable or CAT 5 cable. It should be proper power
cable and the power cable length should be as short as possible. Otherwise relays may not fire.
Q. The system was operating the gates fine, but now it will not trigger the gates.
99% of the time, this is cause by the user accidentally latching the relay. This latches the output
relay permanently on. Send the intercom the following SMS *22#. The intercom should reply with
a message detailing the relay status.. If it has been latched, then the message will state "the relay
is ON". In this case refer to the user guide to read how to unlatch it again.
Q. The unit no longer calls out to phones but I can make a call to it from my phone.
A – Check there is balance on the SIM card.
A – Switch off the power, remove the SIM, put it into a phone, and check that a call can be made
from a phone. This will verify if the SIM is still working and in service.
