Getting started

Battery installation

2.Install four new AA batteries (not included) in the battery compartment according to the labels + and - engraved in the compartment.

3.Close the battery compartment cover. Make sure it clicks into place.

NOTE:

Do not mix old and new batteries and do not mix alkaline and standard (carbon-zinc) batteries.

When the batteries are installed, the screen will show 12:00 and the clock will begin to run. It will reset to the correct time when the first caller ID data is received. If you wish to set the date and time manually, see Time and date on page 17.

Always disconnect all telephone lines from the telephone wall jack before replacing batteries.

Install new batteries every six months to maintain the call log and telephone memory.
