How to fix interference on speech in Videx Intercom System?
- W
  wrightheatherJul 30, 2025
  If you are experiencing interference on the speech with your Videx Intercom System, it could be due to the GSM module increasing its power. Try relocating the antenna or using a more powerful or directional antenna. Also, ensure the antenna cables are not running close to the power supply cables or the microphone wires inside the intercom panel. Finally, try a different SIM card from a different service provider, as they may have better coverage in that area.

  If your Videx Intercom System calls keep dropping out, consider increasing the call time in programming. Also, check the signal strength and, if necessary, move or change the antenna, or try a different SIM card provider.

Why Videx Door panel does not respond to SMS messages?
- D
  Daniel OliverAug 8, 2025
  If the Videx Intercom System panel isn't responding to SMS messages, first check that the SIM card has a SMS service centre number stored (you may need to put the SIM card into a mobile phone to check it). Then, verify that the number you are sending the message to is correct (it should be the number of the SIM card in the intercom panel). You can also try resetting the 4 digit code to 1111 by powering up with C1 & PTE shorted.

How to stop speech echoing and feedback in Videx Intercom System?

  Mary HenryAug 12, 2025
  If the speech echoes and feeds back on your Videx Intercom System, try lowering the speaker volume using jumpers JP2 & JP3. You can also try adjusting the volume using the programmable settings during a call. Additionally, check that the microphone is fitted correctly in the intercom panel and that the mic hole is not blocked in any way.

Why Videx Door makes a long beep when button is pressed?
- R
  rhallAug 16, 2025
  If you hear a long beep when you press a button on your Videx Intercom System, it could be because no telephone number is set up for that button. Check the programming. Also, check the SIM card is fitted correctly.

What to do if Videx Door panel beeps twice and name plate light doesn't work?
- M
  Michelle GuzmanAug 20, 2025
  If the Videx Intercom System panel repeatedly beeps twice and the name plate backlight of the module does not illuminate, check the power supply to ensure it's of adequate voltage and that the jumper JP1 is in the correct position. Try a full reset by powering up with C2 & PTE shorted. You might also try a different SIM card. Note that the intercom module itself may have a fault.

Why Videx Intercom System returns ERROR in SMS or no SMS at all?
- M
  Michael WoodAug 26, 2025
  If you receive an ERROR message in SMS when programming your Videx Intercom System or no SMS is returned even with a '?' at the end, double-check the message against the manual's examples. Common errors include using two apostrophe marks side by side instead of ". To check this, move the cursor along in the message; if the cursor can get between the two “ then it is not the correct character. Also, ensure you're using upper case letters where required (e.g., using STN instead of stn).
