When the unit is powered by the power supply cable, the
inner batteries are fully recharged, then the inner battery
charger is automatically disabled and the batteries discon-
nected in order to keep their charge.
The full charge cycle of a battery set totally discharged re-
quires about 2½ hours, depending on the battery status, and
allows the unit to operate for approximately 9 hours, provided
that the backlight is off.
Backlight reduces considerably battery life. It is recommended
to keep backlight to the minimum level and enable the Battery
Saving function from the Setup menu. This function switches
off the backlight automatically when the unit is not in use.
The battery can discharge even when the unit is off. In this
case, proceed with the recharge cycle.
NOTE: If, when charging the battery, the unit is turned off, the display will warn the
user that the battery charge operation is in progress.
Audio connections
The power supply connector on the cradle can also be used to
connect the earphone or the accessory loudspeaker supplied.
Use the car lighter adapter with loudspeaker to listen to the
car navigator instructions and, at the same time, to charge the
inner batteries.
