• Do not expose a battery to high temperatures, such as direct sunlight or a fire. The battery
may burst, causing a fire or injury.
• Do not attempt to recharge batteries that are not intended to be charged. Charging could
cause the battery to burst or leak, which can cause blindness, chemical burns, or injury.
• If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid should come in
contact with your eyes, mouth, or skin, wash immediately with water and consult a doctor.
Battery fluid is corrosive and may possibly cause loss of sight or chemical burns.

CAUTION
This content indicates “risk of injury.”
Power supply/power cord
• Do not use an AC outlet where the power plug fits loosely when inserted. Failure to observe
this may cause a fire, electric shocks, or burns.
• When removing the electric plug from the unit or an AC outlet, always hold the plug itself
and not the cord. Pulling by the cord can damage it and cause electric shocks or a fire.
• Insert the power plug firmly all the way into the AC outlet. Using the unit when it is not
plugged in sufficiently can cause dust to accumulate on the plug, causing a fire or burns.
Installation
• Do not place the unit in an unstable position where it might accidentally drop or fall over and
cause injuries.
• Do not block this unit's ventilation holes (cooling slits). This unit has ventilation holes on the
top/side/bottom to prevent the internal temperature from becoming too high. Failure to
observe this may trap heat inside the unit, causing a fire or malfunctions.
• When installing this unit:
- Do not cover it with any cloth.
- Do not install it on a carpet or rug.
- Make sure the top surface faces up; do not install on its sides or upside down.
- Do not use the device in a confined, poorly-ventilated location.
Failure to observe the above may trap heat inside the unit, causing a fire or malfunctions.
Ensure that there is adequate space around the unit: at least 30 cm (11-3/4 in) on top,
20 cm (7-7/8 in) on the sides, and 20 cm (7-7/8 in) on the rear.
• Do not install the unit in places where it may come into contact with corrosive gases or salt
air
.
Doing so may result in malfunction.
• Avoid being near the unit during a disaster, such as an earthquake. Since the unit may
turn
over or fall and
cause injury, quickly move away from the unit and go to a safe place.
• Before moving this unit, be sure to turn off the power switch and disconnect all connection
cables. Failure to observe this may damage the cables or cause you or someone else to
trip and fall.
• When transporting or moving the unit always use two or more people. Attempting to lift the
unit by yourself may damage your back, result in other injury, or cause damage to the unit
itself.
• For proper installation of the outdoor antenna, make sure to have it done by the dealer from
where you purchased the unit or by qualified service personnel. Failure to observe this may
cause the installation to fall and result in injury. Installation requires special skills and
experience.
Hearing loss
• Do not use the unit/speakers or headphones for a long period of time at a high or
uncomfortable volume level, since this can cause permanent hearing loss. If you
experience any hearing loss or ringing in the ears, consult a physician.
• Before connecting the unit to other devices, turn off the power for all devices. Also, before
turning the power of all devices on or off, make sure that all volume levels are set to the
minimum. Failing to do so may result in hearing loss, electric shock, or device damage.
• When turning on the AC power in your audio system, always turn on the amplifier or
receiver LAST, to avoid hearing loss and speaker damage. When turning the power off, the
amplifier or receiver should be turned off FIRST for the same reason. Failure to observe the
above may cause hearing impairment or speaker damage.
Maintenance
• Remove the power plug from the AC outlet before cleaning the unit. Failure to observe this
may cause electric shocks.
