5.2.4 TX PWR (TUNE)

The Sub-menu "TX PWR (TUNE)" is used to make TX output power adjustment for
automatic tuning operation. A frequency to be adjusted is any single radio wave.
Tuning power has been set to 10 to 15W regardless of models and frequency bands.
Basically, no field adjustment is required. Be noted that setting tuning output power to
too high level may cause the control relay of the matching circuit to burn out while in
automatic tuning operation.
