CAUTION: To reduce the risk of fire or injury to persons or damage to
the telephone, read and follow these instructions carefully:
Use only alkaline AA batteries (purchased separately).
Dispose of these batteries in a safe manner. Do not burn or puncture. Like
other batteries of this type, if burned or punctured, they could release
caustic material which could cause injury.
Do not open or mutilate the battery. Released electrolyte is corrosive and
may cause damage to the eyes or skin. It may be toxic if swallowed.
Exercise care in handling batteries in order not to create a short circuit. Do
not allow conductive materials such as rings, bracelets, or keys to touch
the battery. The battery or conductor may overheat and cause harm.
Use the battery identified for use with this product only in accordance with
the instructions and limitations specified in this manual.
Observe proper polarity orientation between the battery and metallic
contacts.
Do not disassemble your telephone. There are no user-serviceable parts
inside. Refer to qualified service personnel for servicing.
