  Steven HarrisonAug 21, 2025
  If the DSC Cell Phone shows a Yellow LED flashing six times, it indicates an Ethernet trouble. First, check with your Internet Service Provider (ISP) to make sure Internet service is active. Then, ensure the Ethernet cable is securely plugged into both the RJ45 jack on the communicator and the hub/router/switch. Verify that the link light on the hub/router/switch is on; if it's off, try restarting the hub/router/switch. If you're using DHCP, confirm that the unit has been assigned a valid IP address from the server, and check that a valid IP address is programmed in Sections [851][992].

  If the DSC Cell Phone has a Yellow LED flashing 7 times, it means the receiver is not available. Ensure that the Ethernet path has Internet connectivity. If you are using a static IP address, verify that the gateway and subnet mask are entered correctly. If your network uses a firewall, ensure that 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.

  If the DSC Cell Phone displays both Red and Yellow LEDs flashing together, it means the unit is in the initialization sequence. Wait while the unit gets its programming and establishes a connection to all programmed receivers. Note that this process may take several minutes.

  If your DSC Cell Phone displays a Yellow LED flashing 12 times, it indicates a module configuration trouble. This usually means that the system account code in section [021] or the receiver account code in sections [101] or [111] has not been programmed. Make sure a valid account code has been entered in these sections.
