Appendix A: Maintenance
Taking care of your telephone
Your ET685 Deskset contains sophisticated electronic parts, so you must treat it
with care.
Avoid rough treatment.
Place the corded handset down gently.
Save the original packing materials to protect your ET685 Deskset if you ever need
to ship it.
Avoid water
You can damage your ET685 Deskset if it gets wet. Do not use the corded handset
in the rain, or handle it with wet hands. Do not install the ET685 Deskset 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 electric appliances during storms.
Cleaning your telephone
Your ET685 Deskset 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 a mild
soap.
Do not use excess water or cleaning solvents of any kind.
