Important battery precautions
• Any battery may present a risk of fire, explosion, or chemical burn if abused.
Do not try to charge a battery that is not intended to be recharged, do not
incinerate, and do not puncture.
• Non-rechargeable batteries, such as alkaline batteries, may leak if left in your
product for a long period of time. Remove the batteries from the product if
you are not going to use it for a month or more.
• If your product uses more than one battery, do not mix types and make sure
they are inserted correctly. Mixing types or inserting incorrectly may cause
them to leak.
• Discard any leaky or deformed battery immediately. They may cause skin
burns or other personal injury.
• Please help to protect the environment by recycling or disposing of batteries
according to federal, state, and local regulations.
WARNING: The battery (battery or batteries or battery pack) shall not be exposed
to excessive heat such as sunshine, fire or the like.
Ecology
Help protect the environment - we recommend that you dispose of used
batteries by putting them into specially designed receptacles.
Precautions for the unit
• Do not use the unit immediately after transportation from a cold place to a
warm place; condensation problems may result.
• Do not store the unit near fire, places with high temperature or in direct
sunlight. Exposure to direct sunlight or extreme heat (such as inside a parked
car) may cause damage or malfunction.
• Clean the unit with a soft cloth or a damp chamois leather. Never use
solvents.
• The unit must only be opened by qualified personnel.
Headset safety
To use a headset safely, please keep the following in mind:
• Do not play your headset at a high volume. Hearing experts advise against
continuous extended play.
• If you experience ringing in your ears, turn down the volume or stop using
the headset.
• Do not use a headset while driving a motorized vehicle or riding a bike. It
may cause a traffic hazard and is illegal in many areas.
• Even if your headset is an open-air type designed to let you hear outside
sounds, don’t turn up the volume so high that can’t hear sounds around you.
