Why is there interference on the speech in my Videx GSM4K/4G Intercom System?
Interference on the speech can occur if the signal strength is too low, causing the GSM module to increase its power. Check the signal strength using the command 1111SIG? You can also try relocating the antenna, using a more powerful antenna, ensuring antenna cables are away from power and microphone wires, or trying a different SIM card.
Why is my Videx GSM4K/4G Intercom System not responding to SMS messages but other functions are working?
If your Videx GSM intercom does not respond to SMS messages, but other functions work, the SMS messaging input method on your smartphone might be set to UNICODE. Ensure this setting is set to either GSM alphabet or Automatic.
What to do if the call keeps dropping out on my Videx GSM4K/4G?
If the call keeps dropping out on your Videx Intercom System, try increasing the call time (SPT) in programming. Also, check the signal strength and consider moving or changing the antenna, or trying a different SIM card provider.
What to do if the Videx GSM4K/4G Intercom System panel does not respond to SMS messages?
If the Videx intercom panel does not respond to SMS messages, ensure the SIM card has an SMS service centre number stored. Also, verify that the number you are sending the message to is correct. After sending a message, listen for a single short beep from the intercom panel. You can also try resetting the 4 digit master code to 1111 by powering up with terminals g & 7 shorted.
Why am I getting an ERROR message when programming my Videx Intercom System via SMS?
If you are getting an ERROR message in SMS when programming your Videx Intercom System, or no SMS is returned even with a question mark at the end, it may be due to using two apostrophe marks side by side instead of a quotation mark, or using lower case letters instead of upper case. Check over the message sent again and compare it with the examples in this manual.
How to stop speech echoes and feedback on my Videx Intercom System?
If the speech echoes and feeds back on your Videx Intercom System, try adjusting the volume using the programmable settings during a call. Also, check that the microphone is fitted correctly in the intercom panel and that the mic hole is not blocked.
What does a double beep mean on my Videx GSM4K/4G Intercom System?
The double beep (a single short beep followed by a long beep) on your Videx Intercom System indicates that no telephone number is programmed for that button. Check the programming and also ensure the SIM card is fitted correctly.
Why does the Videx Intercom panel repeatedly beep twice and the name plate not illuminate?
If the Videx Intercom panel repeatedly beeps twice and the back lit name plate of the module does not illuminate, check the power supply has adequate voltage. You can also try a full reset by powering up with terminals g & 8 shorted, or try a different SIM card. The GSM intercom module may have a fault.
