USING REDIAL

REDIAL lets you quickly dial the last number dialed. When you hear a dial tone, simply press REDIAL (REDIAL/P on the base).

Notes:

•The redial memory is independent for each keypad. You cannot redial a number you dialed on the handset keypad using REDIAL/P on the base keypad, and vice versa.

•The redial memory holds up to 32 digits, so you can redial long- distance as well as local num- bers.

•The redial memory also holds pause entries (see “Entering a Pause” on Page 18).

•The redial memory does not store a flash entry or any digits you press after FLASH (see “Using Flash” on Page 16).

USING FLASH

FLASH performs the electronic equiva- lent of a switchhook operation for spe- cial services, such as Call Waiting.

For example, if you have Call Waiting, press FLASH to answer an incoming call without disconnecting the current call. Press FLASH again to return to the first call.

Note: If you do not have any special phone services, pressing FLASH might disconnect the current call.
