What does it mean when the yellow LED on my DSC Cell Phone flashes 5 times?

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.
