3. G 400 module
The G 400 modules incorporate a back-up battery for
short power cuts.
The internal battery can be switched off with a switch
on the front of the G 400. The switch is used when
inserting the SIM card and during transportation and
storage.
When starting up, the internal battery must be con-
nected by pushing the switch to the right.
For switch position, see fig. 2.
On delivery, the battery is completely or partly dis-
charged. It is recommended to allow the G 400 to
charge for min. 2 hours before the GSM communica-
tion is started.
