EK280
− Evaluation:

Logged on to own network; level is 77% and therefore in the acceptable range: Since the system
status shows no entries, the device is also externally supplied (no battery operation)
The level is also relatively constant (no fluctuations or break in of the level)

Modem logged out, although mains power supply is on!
−  Call window closed?
 No connection to the GSM network possible (GSM station switched off...)!

Modem logged out, battery powered! The modem was unable to log on, as the external power
supply failed!
−  E.g. Maybe the EK280 is connected to the lighting system by mistake, so the power to the EK280
is switched off when the light is switched off.
