User's Manual

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 III 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 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 III in order to meet FCC RF exposure limits. Please

contact your organizations’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.

Important

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

may read 100%, when the actual capacity is only 10%.
