In car use and mains operation – connecting the GPS receiver with the charger cable:
Insert the plug (Ø about 2mm) of the car charger cable into the charging socket of the GPS receiver.
(for illustration)
Whilst charging the battery the battery display shows a yellow light. When the battery is fully
charged the yellow light in the battery display disappears. The device is then ready for use. Please
remove the charger cable from the socket of the GPSreceiver and the car charger device from the
cigarette lighter socket or the mains adapter from the mains socket.
For long battery life the GPSreceiver has total discharge protection. About 15 minutes before automatic
shutdown the battery display shows a red light. Please charge the battery promptly.
\
ATTENTION:
Please fully charge the battery for about 1.5 hours before first use.
Normal charging time is about 2 hours. If you charge the GPSreceiver when navigating and the
GPSreceiver is switched on charging can take longer.
Note that a new battery achieves full performance only after having been fully charged and discharged
two or three times! The battery can be charged and discharged hundreds of times but eventually wears
out. If the operating time is clearly shorter than normally the battery must be changed by a qualified
customer service representative.
