Manual Adjustment Mode
Ill While the [ FORWARD ]key is held down, the offset is added to the forward
running side.
[] While the] REVERSE ]key is held down, the offset is added to the reverse
running side.
[] Use the 1-_ key, store offset data, then enter the next mode.
Offset adjustment is performed so that the LED indication may basically be-
come zero; however, the perfect zero state of indication does not always offer
optimum adjustment. Therefore, adjust tile offset carefully, taking actual
motor motion into consideration.
