8.3 Buzzer
A buzzer sounds during PASS or FAIL screening and in the event of an error
due to improper key operations. Two buzzer volume adjustment knobs are
provided on the rear panel: one for PASS screening and one for FAIL
screening. Volume adjustments can be made using the knobs.
1. Check the analog voltmeter and the
DANGER lamp to make sure a voltage
is not being output.
2. Using a No. 0 Phillips screwdriver or 3-mm slotted screwdriver, adjust the
volume adjustment knob. To increase the volume, turn the knob
clockwise. To decrease it, turn it counterclockwise.
