2.Press MEMO. The BATT LOW or SPEAKER indicator blinks.

3.Enter the number and any TONE and PAUSE entries (see “Using Tone Services on a Pulse Line” on Page 17 and “Entering a Pause” on this page).

Note: Each TONE or PAUSE entry uses one digit of memory.

4.Press MEMO, then enter the mem- ory location number (0–9). A sin- gle tone sounds, indicating that the number is stored.

Note: If five quick beeps sound, you have made an entry error and the number was not stored. Start again from Step 2.

5.For each stored number, write the person’s or company’s name next to the appropriate location number on the supplied MEMORY direc- tory sticker. (Use a pencil in case you want to change the number later.)

6.Remove the adhesive backing from the sticker, then attach the sticker to the back of the handset.

To erase a stored number, simply store a new number in its place. Or, press MEMO twice, then press the memory location number (0–9) you want to clear. A tone sounds.

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. You can store the access code with the phone number. However, you should also store a pause after the access code to allow the outside line time to connect.

To enter a 2-second pause, press PAUSE (REDAIL/P on the base). For a longer pause, press PAUSE (or REDI- AL/P) additional times.
