User manual ICOM IC-706MKII

[. . . ] During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications. The heatsink will become hot when operating the transceiver continuously for long periods. If a linear amplifier is connected, set the transceiver's RF output power to less than the linear amplifier's maximum input level, otherwise, the linear amplifier will be damaged. Other manufacturer's microphones have different pin assignments, and connection to the IC-706MKII may damage the transceiver. R NEVER apply AC to the [DC13. 8V] jack on the transceiver rear panel.
