someone calls you while you are already on a call.
• Press FLASH to put your current call on hold
and take the new call.

between calls. For more information on caller
ID with call waiting, refer to About caller ID

NOTES:
• Use FLASH to access other telephone company
subscriber services, as described by your

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

after this send touch-tone signals.
