IMPORTANT! (for 55/50 W transmission):
The ID-800H is equipped with a current detector circuit to
protect the power amplifier circuit from high current flowing.
When a high SWR (Standing wave Ratio) antenna or no an-
tenna is connected, or when the connected power supply’s
voltage includes, the transceiver reduces transmit output
power to 10–20 W (approx.) automatically.
CAUTION: Transmitting without an antenna will damage
the transceiver.
