If you subscribe to call waiting service from your telephone service provider, you hear a beep if someone calls you while you are already on a call.

• Press FLASH to put your current call on hold and take the new call.

• Press FLASH anytime to switch back and forth between calls. For more information on caller ID with call waiting, refer to About caller ID on page 34.

NOTES:

•Use FLASH to access other telephone company subscriber services, as described by your telephone service provider.

•The telephone cannot display the caller ID information if another telephone on the same line is in use. Make sure all extensions are not in use.

Temporary tone dialing

If you have dial-pulse (rotary) dialing service only, use this feature to temporarily switch from dial- pulse to touch-tone dialing during a call.

1. During a call, press TONE*. Buttons pressed after this send touch-tone signals.

2. Use the dial pad keys to enter the relevant number. The telephone sends touch-tone signals.

3. The telephone automatically returns to pulse dial mode after you end the call.
