Sending SMS Commands
All of the features shown on the Android app are also available for non Android users, or non smart phone
users. You can simply send the same SMS commands manually to the intercom as detailed below...
Q. The unit will not power up. No LEDs on.
A. Check power supply voltage at intercom is within 11.5V-12.5V DC. Cable length from PSU to intercom should be less than 3 meters.
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 GSM SIM, not 3G or 4G only 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, 850 / 900 / 1800 / 1900 MHz.
-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.
-Check voltage at the intercom is minimum 11.5V and that the cable from power supply to intercom is less than 3 meters.
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.
Do not put the country code in front of the number.
Enter the country code in which the unit is operating in separate under the 71 feature.
International callers ringing the intercom may not work.
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.
This may also be caused by either a defective microphone. If reception is optimum and the problem persists, contact your supplier or dealer.
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.
-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 * or # key does not work when the intercom calls a phone.
A. Check if you can hear the relay clicking at the gate when the * or # key is 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. Check steps above on improving reception. Try pressing the buttons longer
when attempting to activate the gates or door.
Q. The keypad confirm 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 part of the intercom.
A. Check for voltage drop. If the voltage is a little low, the keypad may operate but fail to fire the relay.

SIM cards & Credit
Please note that if you are using a Pay&Go or Pre-pay SIM card, which requires topped up occasionally, most network
providers provide a feature called Auto Top Up. This allows you to register the SIM card on their web site, and create a
payment method. When the credit runs low, the network will automatically top up your SIM card,
so that you don’t have to
worry about running out. Contact your network provider in your country for more information or register with them online.
