: Requires a specialized "jig plug" connected to specific poles. While some documentation suggests an 8.2 kΩ resistor, practical tests indicate that a combination of resistors (summing to 10.2 kΩ) or a single 65 kΩ resistor may be necessary to trigger the menu. Calibration
Early IC-705 units had issues with the main dial encoder feeling gritty or failing. The full manual shows you how to safely disassemble the chassis to access the encoder board (LOGIC UNIT) without snapping the fragile flat flex cables. icom ic705 service manual full
