User Manual

3. When the battery is fully charged, the Battery Power Indicator remains steady.
Communicating with Other Devices
Connect the external device to either of the USB ports on the back of the cradle, and then place the
GoBook II onto the vehicle cradle. You can install or remove the computer from the vehicle cradle
without connecting or disconnecting the cables.
External Antennas
You can not conect an external RF antenna to the cradle using the SMA RF connector on the back of the
vehicle cradle. . When using the Cisco MPI 350 Series Wireless LAN in the Cradle no external antenna
connection is provided. The SMA RF connector on the standard cradle is not connected or usable for
this application.
Cleaning or Replacing Cradle Contact Pins
The contact pins on the vehicle cradle are exposed to contamination and stress when the computer is
installed and removed from the cradle during normal daily operation. If the pins become dirty, they can
be removed and cleaned as necessary using electrical contact cleaner. Or they can be replaced. The
power and ground pins are pins 3 and 8 respectively. When charging problems are encountered and
replacement pins are not available, other pins in the contact assembly can be used to field fix the unit
until replacement parts are available.
To clean or replace the cradle contact pins
1. Hold down the protective plastic cover.
2. Grasp a pin and pull straight up, being careful not to bend it.
3. Clean the pin with electrical contact cleaner and reinstall it into the cradle contact assembly.
If a pin is bent or cannot be cleaned, contact your support desk to obtain a replacement pin.
NOTE
Pin 8 is not user replaceable. Contact your support desk for information about replacing this RF
connector.

A temperature of 5°C to 50°C (41°F to 22°F) is required when charging batteries with the
vehicle cradle. Batteries will not charge successfully outside this temperature range.

If you charge your battery daily, rely on the gas gauge reading to determine battery
capacity. The gas gauge displayed by the Power Meter may show that the battery is full,
but charging continues. This happens because the charging process is trying to put a little
more capacity into the battery. External power can be removed at this time since the
battery is virtually full.

If your battery is new or has not been used for several weeks, rely on the indicator light to
determine when the battery is fully charged. The gas gauge is unreliable in these cases; it
