Using the Display on the 6402D
Only the 6402D telephone has a 2-line by 16-character display. The basic 
6402 telephone does not have a display. 
The primary uses for the display on the 6402D telephone are:
• Viewing the time and date, which is the usual display. (See Figure 4.)
• Using the Timer (if administered on your dial pad) which shows elapsed 
time on a call (See Figure 4.)

• Viewing call-handling information.
As you dial a telephone number, the individual digits are immediately 
shown on the display as you dial them. When you dial an extension, that 
number is shown and then replaced by the called party’s name. (If there is 
not space for the full name, as many letters of the name as possible will be 
shown on the display.)
When a call is received from another extension, the caller’s name is 
shown; when a call is received from outside, “OUTSIDE CALL” or a trunk 
identifier is shown.
Note:   When a 6400 Series display telephone is initially plugged in or after a 
power outage, it may take approximately 15 minutes before the time 
and date appear on the screen
