Notes:

If you receive a call while you are storing a number in memory, press TALK to answer the call. After the call, begin again at Step 1 to store the number.

To change a phone number stored in memory, simply store a new phone number in that location.

To clear a memory location so no number is stored there, press MEMORY twice, then press the location number. A long beep sounds. The phone number is now cleared from the memory.

If a buzz sounds, you did not suc- cessfully clear the memory loca- tion. Try the process again.

Dialing a Stored Number

There are three ways to dial a stored number.

Method 1

1.Lift the handset from the cradle and press TALK so the keypad and TALK key light.

2.When you hear a dial tone, press MEMORY, then press the number buttons for the correct memory location. The stored number appears on the display, and the phone dials the stored number.

Entering a Pause

in a Memory Number

In some telephone systems, you must dial an access code (9, for example) and wait for a second dial tone before you can dial an outside number. If your phone is connected to one of these systems, you might want to enter a pause at the appropriate point when you store a phone number in memory.

At the appropriate place in the number, press PAUSE to enter a 2-second pause. P appears. For a longer pause, press PAUSE again.

Note: Each PAUSE entry uses one dig- it of memory.

Method 2

1.Lift the handset from the cradle and press TALK so the keypad and TALK key light.
