Telephone calls are transmitted between the headset base and the headset by radio waves, so there is a possibility that your cordless headset conversations could be intercepted by radio receiving equipment within range of the cordless headset. For this reason, you should not think of cordless headset conversations as being as private as those on corded telephones.Electrical power: The headset base of this cordless headset must be connected to a working electrical outlet which is not controlled by a wall switch. Calls cannot be made from the headset if the headset base is unplugged or switched off, or if the electrical power is interrupted.•••••
37AppendixImportant safety informationPotential 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 headset 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 nickel-cadmium, nickel-metal hydride or 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.CAUTIONUse only the batteries provided or their equivalent.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.
