Digital trim
This transmitter is equipped with digital trims.
Each time you press a trim button, the trim position
moves one step. If you continue pressing it, the trim
position starts to move faster. In addition, when
the trim position returns to the center, the tone will
change. You can always monitor trim positions by
graphics on the screen.
To change the trim rate, you must activate this
through the function menu, within the linkage
menu. Use the cursor lever to select the trim box
and then push the enter button and you will access
another screen which enables you to change the
trim percentages.
Note: The trim positions you have set will be stored in the
non-volatile memory and will remain there.
