Adjusting the display
The IP Phone KEM (see Figure 1 on page 3) has 1 LCD between 2 rows of 12 programmable keys
for a total of 24 keys. Each key has a 10-character display label that is set automatically.
To alter the display contrast on the IP Phone KEM, use the Contrast Adjustment option under the
Telephone Options menu on the IP Phone. Any contrast changes you make on the IP Phone affect
the IP Phone KEM. The IP Phone KEM and IP Phone do not have separate contrast adjustments.

IP Phone 2004 User Guide.
