Important safety information
Potential TV interference: Some cordless headsets operate
at frequencies that may cause interference to TVs and VCRs.
To minimize or prevent such interference, do not place the
telephone base of the cordless headset near or on top of a
TV or VCR. If interference is experienced, moving the cordless
headset farther away from the TV or VCR will often reduce or
eliminate the interference.
Rechargeable batteries: This product contains lithium-ion
rechargeable batteries. Exercise care in handling batteries in
order not to create a short circuit with conductive material
such as rings, bracelets and keys. The battery or conductor
may overheat and cause harm. Observe proper polarity
between the battery and the battery charger.
Lithium-ion rechargeable batteries: 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.
The RBRC™ Seal means that the manufacturer is voluntarily
participating in an industry program to collect and recycle
lithium-ion rechargeable batteries when taken out of service
within the United States. These batteries may be taken to a
participating local retailer of replacement batteries or recycling
center. Or you may call 1-800-8-BATTERY for locations accepting
spent Li-ion batteries.
CAUTION
There may be a risk of explosion if you use a wrong type
of battery. Use only the supplied rechargeable battery or
replacement battery (model BT191665).
Change this product's batteries only in accordance with the
instructions and limitations specified in this manual.
As with any batteries, do not allow conductive materials such
as rings, bracelets or keys to come in contact with the metallic
parts of the battery. The battery or conductor may overheat
and cause harm.
