Adjusting The Front Feet - Yaesu FT-920 Operating Manual

Adjusting the Front Feet

The two front feet of the FT-920 can be set in either
of two positions. By turning the knurled ring around a
(retracted) foot clockwise, the middle of the foot will
extend about one centimeter. Turn the ring as far as
it will go (about ¼ turn) to lock the extended foot in
place. To retract an extended foot, turn the knurled
ring counter-clockwise ¼ turn while pressing on the
center of the foot.
