Listening caution
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 poten-
tially hazardous situations.
Even if your headphones or earphones is an 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:
• Set the dial and leave it there.
Rechargeable batteries
• Only the BN-R1213 or HHR-4UP/HHR-4AH (Panasonic) battery can
be recharged.
• Recharging already charged batteries will shorten their service life.
• When recharging batteries for the first time or when they have not been
used for a long period of time, the play time may be shorter than usual.
In a case like this, repeatedly recharge and discharge the batteries. This
will restore them to their regular state.
• Do not allow any metal objects to touch the terminals of rechargeable
batteries since this may cause short-circuiting which is dangerous.
• The rechargeable batteries and charger equipment may generate heat
during recharging. This is not a malfunction.
• If the rechargeable batteries are recharged near a radio receiver, noise
may interfere with AM reception.
• The rechargeable batteries should be recharged under an ambient
temperature between 10 and 35˚C.
•
When the rechargeable batteries are not to be used for a long period, recharge
them at least every 3 months to prevent degradation of performance.
• When the battery operation time from the fully charged condition drops
below half the usual, it is a sign that the service life of the rechargeable
batteries has expired. In this case, replace the rechargeable batteries.
WARNING
• Use only JVC chargers designed for BN-R1213.
• Do not disassemble, dispose of in fire, or short circuit.
• Do not remove the covering.

Carrying dry cell batteries / rechargeable batteries
around
When putting dry cell or rechargeable batteries in a pocket or bag, ensure
that no other metal objects such as a necklace are placed together with
them. Contact with metal may cause short-circuiting which, in turn, may
cause a fire.
Be absolutely sure to carry the rechargeable batteries in the provided
battery carrying case.

struction designed to make it impossible to recharge ordinary batteries.
