Initial Set up
16
The navigation system can be used during the charg-
ing process, but the power supply must not be inter-
rupted during initial set-up.
Leave the external power supply connected to the
navigation system for around 24 hours, so that the
backup battery also charges-up fully.
The external power supply can remain connected;
this is recommended for continuous operation.
Even after a power source has been connected to the
device it may take several minutes until the device is
once again ready to operate again, this occurs if the
charging state of the battery is exceptionally low. The
battery will continue to be charged if the power sup-
ply is connected and the device is switched off.
