4. The Battery and Power Management
The IC-705 is notorious for its power-hungry display. The service manual reveals the power distribution tree: how the BP-272 battery communicates via SMBus to the main CPU. If your radio shuts off at 50% battery, the manual’s power flowchart helps you isolate whether it’s a current sense resistor or a firmware glitch.
