Troubleshooting

•Clean the cordless handset and telephone base charging contacts each month using a pencil eraser or cloth.

•Your phone might be malfunctioning. Please refer to the Limited warranty section of this user’s manual for further instruction.

My caller ID isn’t working.

•Caller ID is a subscription service. You must subscribe to this service from your local telephone company for this feature to work on your phone.

•If you subscribe to high-speed internet service (Digital Subscriber Line - DSL) through your telephone line, you must install a DSL filter between the telephone base and the telephone wall jack. The filter will prevent noise and caller ID problems caused by DSL interference. Please contact your DSL service provider for more information about DSL filters.

•Your caller must be calling from an area that supports caller ID.

•Both you and your caller’s telephone companies must use caller ID compatible equipment.
