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.
