To ob tain the best performance, periodically calibrate
the unit. Sometimes, only one mode need be
calibrated, while at other times, all modes shou ld be
calibrated. When one mode is calibrated, it must be
noted that the other modes may be affected. When
calibrating all modes, perform the calibration in the
specified sequence.
The following calib ration required an accurate
measuring instrument and an insulated adjusting flat
blade screwdriver.
If they are not available, contact your dealer. For
optimum adjust ment, turn the power on and warm up
the unit sufficiently (more than 30 minutes) before
starting. Before calibrating the unit check the power
supply voltage.
