Connecting to an external power source with the serial clip
Use the optional serial clip to connect the GeoExplorer 2008 series handheld to an
external power source. Depending on the optional accessories that you have
purchased, you can use mains power, the external power kit, or a vehicle battery to
supply power to the handheld.
To connect to an external power source:
1. Attach the serial clip to the handheld.
2. Plug the appropriate cable into the power port on the serial clip.
3. Connect the other end of the cable to the external power source. Details about
each type of external power source are as follows:
Recharging from an external power source
By default, the GeoExplorer 2008 series handheld recharges its internal battery from
any external power source that is connected. Recharging the battery draws more
power from the external source than is used to power the handheld.
Note – The life of the battery can be significantly shortened if power is constantly supplied
to the handheld. To avoid this issue, connect the handheld to an external power source
only when the battery requries charging. Once fully charged, disconnect the external power
source and allow the battery to discharge through normal use.
