Notes:

•If you do not have special phone services, pressing FLASH/DEL might disconnect the current call.

•The redial memory does not store a FLASH/DEL entry or any digits entered after you press FLASH/ DEL.

USING TONE SERVICES ON A PULSE LINE

Some special services, such as bank by phone, require tone signals. If you have pulse service, you can still use these special tone services by follow- ing these steps.

1.Set TONE/PULSE on the base to

PULSE.

2.Dial the service’s main number.

3.When the service answers, press

*on the keypad. A appears on the display. Then dial the additional numbers. The phone sends these numbers as tone signals.

4.When you complete the call, place the handset on the cradle or press TALK to disconnect the call. The phone automatically resets to the pulse mode.

Note: We recommend you not use RE- DIAL to dial numbers that include a tone (*) entry.

USING PAGE

The PAGE feature allows someone at the base to page you at the handset. It also helps you find the handset if you misplaced it.

With the handset’s power on, the handset beeps four sets of two beeps when you press PAGE on the base. The TALK key on the handset flashes, and the channel number and INT ap- pear on the display.

Note: The handset will not beep during a call.

MEMORY DIALING

You can store up to 30 phone numbers for quick and easy dialing. Each stored number can be up to 16 digits long.

Notes:

•If TONE/PULSE is set to PULSE and you want to use tone dialing for a memory number, you must store the tone entry along with the number.
