Figure 2-3. Provides the physical size, weight, and front panel lights on the
Remote Unit. The unit is sealed at the manufacturer or repair depot and should not be
opened during field activity. The Remote Unit operates in a sleep mode to extend
battery life. The Remote Unit turns off the display lights while it is sleeping. The
Remote Unit wakes up every 2 seconds to check for a radio signal from the Controller
Unit. The Remote Unit will stay awake for 2 minutes if it detects a radio signal
addressed to it during its wake time. During those 2 minutes, the display lights will be
illuminated as described in Figure 2-3. When the antenna is installed on the Remote
Unit, the Remote Unit performs a self-test of its electronics. The red light will flash on
the Remote Unit if the self-test fails. The Remote Unit should not be used, and should
be returned for repair, if the red light is flashing.
