How to adjust TUNE power
Tune power data is factory-adjusted to 40. Do not change this setting unless
Furuno asks you to change this setting. Too high setting may cause the antenna
coupler to burn out.
1. Select a TX channel. For example, select the ITU channel 401.
2. Press [TUNE/7].
TUNE appears on the display and the coupler starts tuning. When the tuning is
completed successfully, TUNE OK appears.
3. While pressing and holding down [ENT], press [TUNE/7], and TUNE power data
appears.
