Troubleshooting guide

You cannot search through a disc with WMA/MP3 files.

You may not be able to specify point A or B at the end of a disc.

If [:] or [9] is pressed before [$MEMO/%DISP]
you cannot change the mode.

Depending on the type of WMA/MP3 disc recording, the
effect may not appear.

You cannot skip from the last to first album, or vice versa, during play.
The operation tone may be turned off (➪page 5).

≥Remove the plug and reinsert it as fully as possible.
≥

Use only the included remote control to operate the unit.

≥

You aren’t using the special rechargeable batteries (➪page 2).

≥

You must insert two batteries before you can charge.

≥The unit must be off before you can charge.
This is normal.

The batteries may take as long as 6 hours to charge
under some conditions.

≥This may occur the first time you charge the batteries

or if you haven’t used them for a long time. Play time
should be restored after a few charges.

≥The batteries can go flat if you leave the AC adaptor

connected after charging is complete.

≥

If play is extremely short even after fully charging the batteries,
the batteries may have exceeded their life (Rechargeable batteries
can be charged approximately 300 times). Please purchase new
nickel-metal hydride rechargeable batteries (HHF-AZ01).

≥

The indicator does not appear when the AC adaptor is connected.

≥

The indicator may not appear correctly when using the rechargeable

and dry cell batteries at the same time and under certain conditions.
Disconnect then reconnect all power sources (batteries and AC adaptor).
If you connect or disconnect the AC adaptor, the power

cuts off even if the rechargeable batteries are inserted.

1) Read these instructions.

2) Keep these instructions.

3) Heed all warnings.

4) Follow all instructions.

5) Do not use this apparatus near water.

6) Clean only with dry cloth.

7) Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions.

8) Do not install near any heat sources such as radiators, heat registers, stoves,
or other apparatus (including amplifiers) that produce heat.

9) Do not defeat the safety purpose of the polarized or grounding-type plug. A
polarized plug has two blades with one wider than the other. A grounding­type plug has two blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the provided plug does not fit into
your outlet, consult an electrician for replacement of the obsolete outlet.

10) Protect the power cord from being walked on or pinched particularly at
plugs, convenience receptacles, and the point where they exit from the
apparatus.

11) Only use attachments/accessories specified by the manufacturer.

12) Use only with the cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury
from tip-over.

13) Unplug this apparatus during lightning storms or when
unused for long periods of time.

14) Refer all servicing to qualified service personnel. Servicing is required when
the apparatus has been damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.

Read these operating instructions carefully before using the unit. Follow the
safety instructions on the unit and the applicable safety instructions listed below.
Keep these operating instructions handy for future reference.

Discontinue use if you experience discomfort with the earphones or any other parts that
directly contact your skin. Continued use may cause rashes or other allergic reactions.

∫Batteries
≥

Do not peel off the covering on the batteries and do not use if the covering has been peeled off.

≥Align the poles i and j correctly when inserting the batteries.
≥Do not mix different types of batteries or old and new batteries.
≥

Remove the batteries if you do not intend to use the unit for a long time.

≥Do not throw into a fire, short-circuit, disassemble, or subject to excessive heat.
≥Do not attempt to recharge dry cell batteries.
≥When carrying batteries in a pocket or bag, ensure no metal objects such as

necklaces are placed together with them. Contact with metal may cause
short-circuiting which can cause a fire. For safety, carry the rechargeable
batteries in the battery carrying case.

∫CDs
≥Do not use irregularly shaped CDs.
≥Do not use non-specification CDs.
≥Do not use CDs printed with label printers available on the market.
≥Do not use CDs with labels and stickers that are coming off or with adhesive

exuding from under labels and stickers.

∫Listening

Do not play your headphones or earphones at a high volume. Hearing experts
advise against continuous extended play.
If you experience a ringing in your ears, reduce volume or discontinue use.
Do not use while operating a motorized vehicle. It may create a traffic hazard and
is illegal in many areas.
You should use extreme caution or temporarily discontinue use in potentially hazardous situations.
Even if your headphones or earphones are the open-air type designed to let you hear
outside sounds, don’t turn up the volume so high that you can’t hear what’s around you.
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:
≥Leave it there.
