GD8000 User Guide Optional Equipment and Accessories CAUTIONS „„ Refer to Battery Tips for recommended charging temperature ranges and other recommendations „„ If you charge the battery daily rely on the gas gauge reading to determine battery capacity. The gas gauge may show that the battery is full while still charging. 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%. Recalibrate the battery to correct this issue. Memory Upgrade Adding memory allows the computer to operate faster, handle more tasks simultaneously, and work more smoothly with large files.

Communicating with Other Devices Connect external devices to the ports on the back of the dock, and then place the GD8000 onto the vehicle dock. You can install or remove the computer from the vehicle dock without connecting or disconnecting the cables. External Antennas The vehicle dock integrates WLAN and WWAN antennas with switching capability. You can also connect an external RF antenna to the dock using the SMA RF connector on the back of the vehicle dock. FCC regulations require that users of vehicle-mounted antennas must use only antennas authorized for use with the GD8000 in order to meet FCC RF exposure limits. Please contact your organizations's help desk for a list of approved vehicle-mounted antennas. Before mounting an external antenna, refer to the installation instructions provided with the antenna. Vehicle-mounted 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 and at least 92cm (36 inches) from any existing roof mounted antennas. 1. Measure and identify an area 20 cm (8 inches) in from the edges of the vehicle roof. 2. Place the antenna within that area. To maximize RF performance, position the antenna in the center of the vehicle roof. CAUTION Do not place any metal objects on top of the dock that might make contact with the metal pins of the contact connector. Doing so may cause an electrical short and subsequent damage to the dock. General Dynamics Itronix | 72-0137-003
