Especially about cordless headsets

•

•

•

Privacy: The same features that make a cordless headset convenient create some limitations. 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.

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 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.

Maintenance and Troubleshooting

Important safety information

•

•

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 lithiumion 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

•

Use 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 metalic parts of the battery. The battery or conductor may overheat and cause harm.

Do not open or damage the batteries. Released electrolyte is corrosive and may cause injury to the eyes or skin. The electrolyte may be toxic if swallowed.

Do not dispose of the batteries in a fire. Check with local waste management codes for special disposal instructions.

Precautions for users of implanted cardiac pacemakers

Cardiac pacemakers (applies only to digital cordless telephones):

Wireless Technology Research, LLC (WTR), an independent research entity, led a multidisciplinary evaluation of the interference between portable cordless telephones and implanted cardiac pacemakers. Supported by the U.S. Food and Drug

Administration, WTR recommends to physicians that:

PACEMAKER PATIENTS

•

•

Should keep cordless telephones at least six inches from the pacemaker.

Should NOT place cordless telephones directly over the pacemaker, such as in a breast pocket, when it is turned ON.

• Should use the cordless telephone at the ear opposite the pacemaker.

WTR’s evaluation did not identify any risk to bystanders with pacemakers from other persons using cordless telephones.
