● Starting Self-Diagnostic Function in
the protection cancel mode
If the protection function works and causes hindrance
to troubleshooting, cancel the protection function by
the procedure below, and it will be possible to enter the
selfdiagnostic function mode. (The protection functions
other than the excess current detect function will be
disabled.)
While pressing the “TONE CONTROL” and “INFO” keys,
press the “z” (Power) key to turn on the power and keep
pressing those 2 keys and “z” (Power) key for 3 seconds
or longer.
The self-diagnostic function mode is activated with the
protection fun
In this mode, the “SLEEP” segment of the FL display
flashes to indicate that the mode is self-diagnostic
function mode with the protection functions disabled.
CAUTION!
Using this unit with the protection function disabled may
cause further damage to this unit. Use special care for
this point when using this mode.

• Some internal parts in this product contain high voltages and are dangerous. Be sure to take safety measures during
servicing, such as wearing insulating gloves.
• Note that the capacitors indicated below are dangerous even after the power is turned off because an electric charge
remains and a high voltage continues to exist there. Before starting any repair work, connect a discharging resistor
(5 k-ohms/10 W) to the terminals of each capacitor indicated below to discharge electricity. The time required for
discharging is about 30 seconds per each.

Be sure to take safety measures during servicing, such as wearing insulating
gloves.
• Note that the capacitors indicated below are dangerous even after the
power is turned off beca use an electric charg e remains and a high
voltage continues to exist there. Before starting any repair work, connect
a discharging resistor
(5 k-ohms/10 W) to the terminals of each capacitor
indicated below to discharge electricity. The time required for discharging is
about 30 seconds per each.

安全対策
・ この製品の内部には高電圧部分があり危険です。修理の際は、絶縁性の手袋
を使用するなどの安全対策を行ってください。
・ 下記のコンデンサには電源を OFF にした後も電荷が残り、高電圧が維持され
ており危険です。修理作業前に放電用抵抗(5 k Ω /10 W)を下記の各コンデ
ンサの端子間に接続して放電してください。放電所用時間は各々約 30 秒間
です。
