Testing the RSSI value

During the enrolling procedure, it is mandatory to check the RSSI value (signal strength) of the NX-
7002 and record it in the system documentation. The RSSI value is linked to the signal level of the
GSM network and ranges from 0-31, with 99 as unknown.
The RSSI value may change due to environmental circumstances, for example, additional furniture or
metal constructions. If an RSSI reading is not satisfactory, move the antenna to get a better reception.
