personnel before operating it any further.
• Do not put any foreign objects in the DC IN
4.5 V (external power input) jack.
On power sources
• When you are not using the unit for a long
time, disconnect all power sources from the
unit.
• The nameplate indicating operating voltage,
power consumption, etc. is located at the
bottom of the AC power adaptor (for Middle

your unit is not supplied with it, use AC-
E45HG AC power adaptor. Do not use any
other AC power adaptor.
• To unplug the AC power adaptor from the wall
outlet, grasp the adaptor itself, do not pull its
cord.
On dry and rechargeable batteries
• Do not throw the batteries into fire.
• Do not carry the rechargeable battery with
coins or other metallic objects. It can generate
heat if the positive and negative terminals of
the battery are accidentally contacted by a
metallic object.

it. If you do so, the lens may be damaged and
the unit will not operate properly.

television reception, turn off the unit or move it
away from the radio or television.

during use as it may cause malfunction or
serious accidents.
On headphones
Road safety
Do not use headphones while driving, cycling, or
operating any motorized vehicle. It may create a
traffic hazard and is illegal in some areas. It can
also be potentially dangerous to play your
headsets at high volume while walking,
especially at pedestrian crossings. You should
exercise extreme caution or discontinue use in
potentially hazardous situations.
Preventing hearing damage
Avoid using headphones at high volume.
Hearing experts advise against continuous, loud
and extended play. If you experience a ringing
in your ears, reduce volume or discontinue use.
Caring for others
Keep the volume at a moderate level. This will
allow you to hear outside sounds and to be
considerate to the people around you.
Maintenance
To clean the lens
Clean the lens with a lens cleaning kit KK-DM1.
To clean the casing
Use a soft cloth slightly moistened in water or a
mild detergent solution. Do not use alcohol,
