Put the headphones on and ad
just the volume.

Since this unit utilizes an infrared beam, in pro
portion to the range from the infrared beam trans
mitter, hiss may increase. Interception of the

infrared beam causes noise or a break in
sound.

These phenomena are not an indication that the
unit is out of order.

• Use the headphones within the range described
in “Installation”.

• Obstructions decrease the effectiveness of the
sensor. Keep your hands away from the sen
sors.

Installation

These headphones use an infrared beam. The
approximate area in which the infrared beam
from the transmitter (beam emitter) can reach the
headphones (beam sensor) is shown in the fig
ure. Install the infrared beam transmitter inside
the area indicated,

.Notes.

•The infrared beam does not pass through walls
or window panes. The headphones must be
used where the infrared beam transmitter is di
rectly visible without any obstructions.

•Do not expose the headphones to direct sun
light or to the bright light of an invertor fluores
cent light.

Maintenance

To clean this unit, wipe with a soft, dry cloth.

If the surfaces are extremely dirty, use a soft
cloth dipped in a soap-and-water solution or a
weak detergent solution.

• Never use alcohol, paint thinner or benzine to
clean this unit.

•Before using chemically impregnated cloth,
read the instructions that came with the doth

carefully.

Battery installation

The headphones are powered by two R03/LR03

(AAA, UM-4, not included) batteries. Insert one
battery each into the battery compartments on

the headphones.

Inserting the batteries:

Push up on the triangle and open the battery compartment lid.

Insert the battery observing po
larity.

Put the lid back on the compart
ment.

How to tell when to change the batteries;

The OPR/BATT indicator on the right hand side

headphone lights up when the headphones are
switched on with the OPR switch. When the bat
teries run down, the indicator dims or fails to light

up. Noise and interference also increase.
Change the batteries if any of these occur.

If rechargeable batteries are to be used,
rechargeable batteries manufactured by
Panasonic are recommended.

GSGíflaii

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.

Handle the AC adaptor carefully. Improper han
dling is dangerous.

©Do not touch it with wet hands.
©Do not place heavy objects on top of it.
©Do not forcibly bend it.

Be sure to connect only the AC adaptor provided

with the unit.

Disconnect the AC adaptor from the power outlet

if the unit is not going to be used for a long time.

You should use extreme caution or temporarily
discontinue use in potentially hazardous situa
tions.

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.
