3.Press CONF. The TALK/BATT LOW indicator briefly flashes and remains steadily on, and you can talk with both parties.

To end the conference call, press TALK or return the handset to the base. If you want to hang up one line and continue talking on the other, press the line button for the line you want to keep.

USING REDIAL

REDIAL lets you quickly dial the last number dialed on either LINE 1 or LINE 2. When you hear a dial tone, simply press REDIAL.

Notes:

•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 19.

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

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.
