Communication Loss

Upon loss of communication with the panel, the PCS250G LEDs will behave in the following manner:

1) GPRS LED displays is off; the SIM card and signal strength

LEDs display their status for about 3 seconds.

2) Signal strength LED remains OFF; GPRS (green) is turned

ON, followed in turn by SIM2 (orange) and SIM1 (red). When a LED is ON, all others are off. Each LED lights for about 200 ms. This sequence is repeated two times.

3) This cycle repeats until communication is restored.
