Using Flash
1 Press FLASH instead of the switch-
hook when using custom calling
services or when activating certain
Centrex or PBX features.
Press the FLASH button instead of pressing the
switchhook to activate services such as Call
Waiting or 3-Way Calling, or to activate certain
PBX or Centrex features. You may be required
to press other buttons before or after you press
FLASH. Refer to the custom calling instructions
provided by your local telephone company or to
the operating instructions provided with your
PBX.
You can store a switchhook flash into a memory
location. When you store a flash, it is represent-
ed in the display by a small “f”. (See page 48.)
Note: The initial factory-set flash length is 700
milliseconds, which is appropriate for most
installations. However, you can adjust the flash
length to make it longer or shorter. (See page
109.)
