Special Notes

E-3
1. Radio frequency exposure
Wireless Bone Conduction Headphones is a radio transmitter and receiver. When in
operation it communicates with a Bluetooth®equipped mobile device by receiving
and transmitting radio frequency (RF) electromagnetic elds (microwaves)
in the frequency range 2.4 to 2.48 GHz. This product is designed to operate in
compliance with the RF exposure guidelines and limits set by national authorities
and international health agencies when using compatible mobile phone.
2. Battery information
●A rechargeable battery has a long service life if treated properly.
●A new battery or one that has not been used for a long period of time could
have reduced capacity the rst few times it is used. Do not expose the battery to
extreme temperatures, never above 50°C (122°F) or below -10°C (14°F).
●For maximum battery capacity, use the battery at room temperature.
●If the battery is used in low temperatures, the battery capacity will be reduced.
The battery can only be charged in temperatures between 5°C (41°F) and 40°C
(104°F).
●RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
3. Removal of waste batteries and accumulators
(Product with embedded battery ONLY)
●In case this product contains a battery incorporated within the product which

for their own safety, users should not attempt to remove the battery and should
contact authorised independent service providers for advice.
CAUTION:
Internal lithium battery in the unit should not be replaced by end users due to
danger of explosion if battery is incorrectly replaced and must be replaced with the
exact type battery by authorised service providers.
Avoiding hearing damage
If volume on the headphones is too high, permanent hearing loss may occur. Please
set the volume to a safe level. You can become habitual to hear at high volume that
may sound normal but can damage your ears. If you experience ringing in your
ears or mufed speech, stop listening and have your ears checked by the specialist
doctor. The louder the volume, the more quickly the hearing can be damaged.
Hearing experts suggest how to protect your hearing
●Limit the amount of time you use the headphones at high volume.
●Avoid the habit of increasing the volume so that you do not hear the loud noises
around you.
●Turn the volume down if you cannot hear people speaking around you.
For setting the maximum volume limit of the connection device,
refer to the instruction manual supplied with the connection device.
Class B equipment (home-use broadcasting communication equipment):
This equipment is intended for home-use (Class B) electromagnetic compatibility
equipment and can be used in all areas.
High sound pressure.
Hearing damage risk.
Do not listen at high volume levels for long periods.

E-5
Precautions
The sound level at a given volume setting depends on speaker efciency, location
and various other factors. It is advisable to avoid exposure to high volume levels,
which occurs while turning the unit on with the volume control setting up high,
or while continually listening at high volumes. Excessive sound pressure from
headphones can cause hearing loss. Adjust the volume to an appropriate level
when using the unit.
●Do not cover the product with items, such as news papers, tablecloths, curtains,
etc. while charging.
●Keep the unit away from strong magnetic elds, excessive dust, humidity
and electronic/electrical equipment (home computers, facsimiles, etc.) which
generate electrical noise.
●Do not expose the unit to temperatures higher than 40 °C (104°F) or to extremely
low temperatures.
●Do not remove the outer cover. Refer internal service to your local SHARP
service facility.
●No naked ame sources, such as lighted candles, should be placed on the
apparatus.
●Attention should be drawn to the environmental aspects of battery disposal.
●This unit should only be used within the range of 0°C - 40°C (32°F - 104°F).

CAUTION: Risk of explosion if the battery is replaced by an incorrect type
●high or low extreme temperatures that a battery can be subjected to during use,
storage or transportation; and
●low air pressure at high altitude.
●replacement of a battery with an incorrect type that can defeat a safeguard (for
example, in the case of some lithium battery types);
●disposal of a battery into re or a hot oven, or mechanically crushing or cutting of
a battery, that can result in an explosion;
●leaving a battery in an extremely high temperature surrounding environment that
can result in an explosion or the leakage of ammable liquid or gas;
●a battery subjected to extremely low air pressure that may result in an explosion
or the leakage of ammable liquid or gas.
