  If the yellow LED on your DSC Cell Phone flashes 5 times, confirm that cellular service is available and active in your area. Check all antenna connections. Ensure average radio signal strength is CSQ 5 or higher. Ensure the SIM card is properly inserted into the SIM card holder and that it has been activated (this could take up to 24 hours after install). If this trouble persists, relocate the panel (and communicator) or install an external antenna extension kit.

  If the yellow LED on your DSC Security System flashes 7 times, it means the receiver is not available. First, ensure that the Ethernet path has internet connectivity. If you are using a static IP address, verify that the gateway and subnet mask are programmed correctly. If a firewall is present, ensure the programmed outgoing ports are open (Default UDP Port 3060 and Port 3065). Also, ensure that all receivers are programmed for DHCP or have the correct IP address and port number. Finally, confirm that the system and all receivers are programmed with a valid account number.

  If the trouble LED on your DSC Security System flashes twice, it indicates a panel supervision trouble. Check that panel Section [382] Toggle [5] is set to ON, which enables the Ethernet Module. Also, ensure the PC-Link cable between the Control Panel and the Communicator is connected properly (not reversed) and securely in place.

  If the yellow LED on your DSC Security System flashes 12 times, it means there's a module configuration trouble. This usually happens when the System Account Code or Receiver Account Code is programmed with all 0s or all Fs (e.g., FFFFFF). To fix this, check Sections [851][021], [101], and [111] to confirm the account numbers.
