11.6 Indication of network service availability

The STAT_LED pin status shows information on the network service availability and Call status.

In the UC864-E modules, the STAT_LED usually needs an external transistor to drive an external LED.

Therefore, the status indicated in the following table is reversed with respect to the pin status.

LED status	Device Status
Permanently off	Device off
Fast blinking	Net search / Not registered /
(Period 1s, Ton 0,5s)	turning off
Slow blinking	Registered full service
(Period 3s, Ton 0,3s)
Permanently on	a call is active
