Contrast
Note: The “Contrast” parameter is not available for 8255 terminals equipped
with vacuum fluorescent displays.
This parameter is used to adjust the terminal screen contrast. The allowable range is
-5 to 5. The higher the value assigned, the darker the screen contrast.
7.5.2 Key Click
The parameters in the Key Click sub-menu are used to adjust the sound emitted
from the terminal when a key is pressed. When “Key Click” is set to Y, an audible
sound is emitted from the terminal with each key pressed. Setting this parameter to
“N” disables the key click sound.
Tone
The value entered in the “Tone” parameter determines the frequency of the key
clicks and is measured in Hz. The allowable range is 200 to 5000. The higher the
value, the higher the pitch.

The value entered in the “Duration” parameter measures the length of time a sound
is emitted when a key is pressed and is measured in milliseconds. The allowable
range is 25 to 150.
