Cautions

Listening caution

Selection and care of rechargeable /dry cell batteries

EST. 1924

Do not play your headphones or earphones at a high volume. Hearing experts advise against continuous ex- tended 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 discon- tinue 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 “com- fort 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 com- fortably and clearly, and without distortion.

Once you have established a comfortable sound level: Leave it there.

Selection

As a safety precaution, the portable CD players made by Panasonic are constructed so it is impossible to recharge ordinary batteries.

Only batteries especially designed for this unit can be recharged.

Special rechargeable Ni-Cd batteries:

P-3GAVA/2B (set of 2)

If rechargeable battery play time is short after recharg- ing, the batteries have reached the end of their service life. Replace them with the recommended replace- ments.

Play time may be shorter than usual after recharging batteries for the first time or after they have been un- used for a long time. Repeatedly recharge and dis- charge the batteries if this occurs to restore them to normal.

Care

To prevent battery damage, electrolyte leakage and short-circuiting, heed the following points.

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

Align the poles + and - 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 fire, short-circuit, disassemble, or subject to excessive heat.

Do not attempt to recharge dry cell batteries.

Do not allow metal objects to touch the battery termi- nals as this may cause short-circuiting which is dan- gerous.

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-circuit- ing which can cause a fire. For safety, carry the batter- ies in the battery carrying case.

When driving a car

In the interest of traffic safety, do not operate the unit while driving.

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