2-2 Radio Power: General
Figure 2-1. DC Power Distribution—UHF Range 1 and 700–800 MHz Radios
Figure 2-2. DC Power Distribution—VHF Radios
B+ from the battery is electrically switched to most of the radio, rather than routed through the On/
Off/volume control knob, S1. The electrical switching of B+ supports a keep-alive mode. Under
software control, even when the On/Off/volume control knob has been turned to the Off position,
power remains on until the MCU completes its power-down, at which time the radio is physically
powered down.
