Before turning the power on, make sure the
volume control of this unit is set to the low
(‘‘0—*1") position.
Operation indicator (safety operation)
When the power is switched on, this indicator flashes on and off for about 5
seconds, and then illuminates steadily when the unit is in the operation
condition. If an abnormal condition in the circuitry is detected, such as DC
voltage appearing in the output, or a short-circuit of the positive (+) and

and this indicator flashes rapidly. If this occurs, switch the power off, find the
cause of the trouble and correct it, and then switch the power on once again.
