User's Manual Part 1

PRECAUTIONS
¡
There are no user-replaceable parts within the vehicle cradle, so do not open the cradle case. The vehicle cradle is internally
protected; it resets automatically if there is a power fault.
¡
Do not use the vehicle cradle to charge the computer battery overnight. Turn off the vehicle cradle at the end of each work day to
prevent draining the voltage in your vehicle’s battery below starting levels.
Charging Batteries
The vehicle cradle is designed to charge the computer’s battery with voltage from the vehicle battery while you are traveling between
jobs. Follow the procedure below to charge a battery.
To charge a battery installed in the computer
1. Place the computer onto the vehicle cradle, making sure it is securely latched.
2. If charging is required it begins automatically. The Battery Power Indicator flashes.
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.
Vehicle Mount Antennas
You can also connect an external RF antenna to the cradle using the SMA RF connector on the back of the vehicle cradle. FCC
regulations require that users of vehicle-mounted antennas must use only antennas authorized for use with the GoBook II in order to
meet FCC RF exposure limits. Please contact your organization’s help desk for a list of approved vehicle-mounted antennas. For
mounting installation and/or mounting instructions for these types of antennas, see the instructions that accompany each antenna.
RF Antenna Placement
WARNING Improper installation and/or operating configurations of permanent and magnetic vehicle-mounted antennas may cause
FCC RF exposure limits to be exceeded. Vehicle-mounted antennas must be placed at least 20 cm from operators and bystanders.
Placement of a vehicle-mounted antenna
1. Measure and identify an area 20 cm (8 inches) in from the edges of the vehicle roof (see diagram below).
2. Place the antenna within that area.
To maximize RF performance, position the antenna in the center of the vehicle roof.
Important
l
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.
l
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.
l
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
may read 100%, when the actual capacity is only 10%.
