Sound suddenly stops or

unit is switched on.
“OVERLOAD” appears on
the display.
The protection circuitry has functioned
because: the positive and negative speaker
wires have shorted; speakers with a lower
impedance than this unit’s rated impedance
are being used; the speakers are under
strain through excessive volume, excessive
power, or by being used in a high
temperature environment.
® Switch off the unit, determine and correct
the cause, then switch the unit on.
• Use speakers with the right impedance
rating.

About the HELP function
If you make a mistake in operation or if sound output stops due to
some operation which was performed, the HELP function displays
information which can be useful for indicating the method by which
this condition can be remedied.
If “ERROR" or scrolling characters (for instance, “SPEAKER OFF
NOW”) appear on the display during operation, carry out the
following operation.
Press [-HELP/-RESET].
The method for remedying this situation will be displayed.
For your reference
If the above button is pressed for 2 seconds or more until
“RESET’ appears on the display, the operation settings for the unit
will be initialized to the settings made at the time of shipment.
However, any stations which have been preset into memory will not
be erased at this time.
Listening caution
Selecting fine audio equipment such as the unit you’ve just
purchased is only the start of your musical enjoyment. Now it’s
time to consider how you can maximize the fun and excitement
your equipment offers. This manufacturer and the Electronic
Industries Association’s Consumer Electronics Group want you to
get the most out of your equipment by playing it at a safe level.
One that lets the sound come through loud and clear without
annoying blaring or distortion—and, most importantly, without
affecting your sensitive hearing.
We recommend you to avoid prolonged exposure to excessive
noise.
Sound can be deceiving. Over time your hearing “comfort level”
adapts to higher volumes of sound. So what sounds “normal” can
actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level
BEFORE your hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and
clearly, and without distortion.
Once you have established a comfortable sound level:
• Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing
damage or loss in the future. After all, we want you listening for a
lifetime.
