Maintenance

Taking care of your headset

•Your cordless headset contains sophisticated electronic parts, so it must be treated with care.

•Avoid rough treatment.

•Place the headset down gently. Save the original packing materials to protect your headset if you ever need to ship it.

Avoid water

•Your headset can be damaged if it gets wet. Do not use the headset outdoors in the rain, or handle it with wet hands. Do not install the headset charger near a sink, bathtub or shower.

Electrical storms

•Electrical storms can sometimes cause power surges harmful to electronic equipment. For your own safety, take caution when using electrical appliances during storms.

Cleaning your headset

•Your headset has a durable plastic casing that should retain its luster for many years. Clean it only with a soft cloth slightly dampened with water or mild soap.

•Do not use excess water or cleaning solvents of any kind.

Remember that electrical appliances can cause serious injury if used when you are wet or standing in water. If the telephone base should fall into water,

DO NOT RETRIEVE IT UNTIL YOU UNPLUG THE POWER CORD AND TELEPHONE LINE CORD FROM THE WALL. Then pull the unit out by the unplugged cords.
