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.

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.
