Hearing safety
Be sure to observe the following
guidelines when using your earpieces.
• Listen at reasonable volumes for
reasonable periods of time.
• Be careful not to adjust the volume
continuously upwards as your
hearing adapts.
• Do not turn up the volume so high
that you can't hear what's around
you.
• You should use caution or
temporarily discontinue use in
potentially hazardous situations.
• Excessive sound pressure from
earpieces and earpieces can cause
hearing loss.
• Using earpieces with both ears
covered while driving is not
recommended and may be illegal in
some areas.
• For your safety, avoid distractions
from music or phone calls while in
trac or other potentially dangerous
environments.
Danger
To avoid hearing damage, limit the time you
use earpieces at high volume and set the
volume to a safe level. The louder the
volume, the shorter the safe listening time is.
General information
To avoid damage or malfunction:
Operating and storage temperatures
and humidity
• Store in a place where the
temperature is between -20°C (-4°F)
and 50°C (122 °F) with up to 90%
relative humidity.
• Operate in a place where the
temperature is between 0°C (32°F)
and 45°C (113 °F) with up to 90%
relative humidity.
• Battery life may be shorter in high or
low temperature conditions.
• Replacement of a battery with an
incorrect type risks severely
damaging the earpieces and the
battery (for example, in the case of
some lithium battery types).
Caution
Do not expose earpieces to excessive heat.
Do not drop your earpieces.
Earpieces shall not be exposed to dripping or
splashing. (Refer to the IP rating of specic
product)
Do not allow your earpieces to be submerged
in water.
Do not charge your earpieces when the
connector or socket is wet.
Do not use any cleaning agents containing
alcohol, ammonia, benzene, or abrasives.
If cleaning is required, use a soft cloth, if
necessary dampened with a minimum amount
of water or diluted mild soap, to clean the
product.
The integrated battery shall not be exposed to
excessive heat such as sunshine, re or the like.
Danger of explosion if battery is incorrectly
replaced. Replace only with the same or
equivalent type.
To achieve the specic IP rating, the charging
slot cover must be closed.
Disposal of a battery into re or a hot oven, or
mechanically crushing or cutting a battery, can
result in an explosion.
Leaving a battery in an extremely high
temperature surrounding environment can
result in an explosion or the leakage of
ammable liquid or gas.
A battery subjected to extremely low air
pressure may result in an explosion or the
leakage of ammable liquid or gas.
