Adjustment

procedure

Place the standard object at the specified

position. Slowly turn the SENSITIVITY

adjuster clockwise (toward “High”) and stop

it when the OPER. indicator illuminates.

Move the object to confirm that the OPER.

indicator is ON when the object is at the

specified position and that it is OFF when

the object is moved away from that

position.
