  If the yellow LED on your DSC Computer Hardware flashes 5 times, it signals a cellular trouble. To resolve this, confirm that cellular service is available and active in your area. Check all antenna connections to ensure they are secure. Make sure the average radio signal strength is CSQ 5 or higher. Verify that the SIM card is properly inserted into the SIM card holder and that it has been activated, which can take up to 24 hours after installation. If the trouble persists, consider relocating the panel and communicator or installing an external antenna extension kit.
