Tuning the antenna
Before using the selected channel, the antenna must be tuned to the transmission
frequency. The procedure used to tune the antenna depends upon the type of antenna
you are using. This may be:
• an automatic tuning whip antenna
• a multi-frequency tapped whip antenna
• an antenna tuner with antenna.
The transceiver also has an auto tune facility which automatically tunes the antenna
when the Call, B’con or Emgcy button is pressed.
