With an obstructing object between the sensors (ideally, a full reel of cover tape), press
and release the
SET
button. The
PV Indicator
will be lit.
2.
Remove the obstruction between the sensors and press
SET
again. The amplifier will
return to its normal operating mode. The number shown on the
PV Indicator
should
change.

If the sensor is in dark-ON mode, the operation indicator should be lit while there is an
obstruction between the sensors. If the sensor is in light-ON mode, the operation indica-
tor should be lit while there is no obstruction between the sensors.
