Antenna Tuner - Icom IC-746PRO Manual

• Momentary pushing the switch turns the antenna tuner ON and OFF.
• Pushing for 1 second manually starts the antenna tuner.
– The internal automatic antenna tuner matches the transceiver to the connected
antenna automatically. Once the tuner matches an antenna, the variable capacitor
angles are memorized as a preset point for each frequency range (100 kHz steps).
Therefore, when you change the frequency range, the variable capacitors are
automatically preset to the memorized point.
• CAUTION: NEVER transmit with the tuner ON when no antenna is connected. This
will damage the transceiver. Be careful of the antenna selection.
