including the radio, can only run from an external supply. When connected to an external
supply, the charger circuitry is switched on and connected to the internal battery. The
Charge and Battery Status Indicator LEDs turn on (red). When the transportable is not in
use, always switch the battery select switch to External DC/Battery Isolate.
Notice
The on/off switch on the radio control head is disabled.
Battery Power
With a fully charged battery, an operating regime of 5% transmit at 25W, 5% receive, and
90% standby time will keep the transportable running for a minimum of six hours. This
shift life takes into account the fact that the onboard Mobile Computer Platform operates
continuously while the transportable is switched on.
Battery Charging
Warning
The lid must be open when charging. The VRLA battery may vent when
charged at a current greater than 3A. This does not occur during normal charging.
The transportable will shut itself down when the internal battery voltage drops too low.
When that level of discharge has been reached, it will take a bench-top power supply
producing 13.8V typical (10–30VDC) at least 12 hours to recharge the battery to full
capacity. When charging, ensure the battery select switch is set to External DC/Battery
Isolate. Press the recessed button located at the left of the Charge LED to turn charging off
and on.
A charging cable is supplied with the transportable for connection to the DC Input
connector.
Antenna
The transportable is a 25W radio that requires a remote mounted antenna with a suitable
ground plane. This antenna is to be tuned to the frequency of the radio. The transportable
has an N-type antenna connector.
Caution
While you are transmitting (talking or sending data) on the radio, you must
ensure that there is always a distance of 0.9m between people and the antenna. This is
the minimum safe distance.
