Repeat Delay
The value assigned for this parameter determines the delay in milliseconds between repeat characters.
Sliding the
Repeat Delay bar to the left increases the delay between key repeats, and sliding the bar to the
right shortens the repeat delay time.
Repeat Rate
The value assigned for the Repeat Rate parameter determines how quickly the key you press repeats and is
measured in characters per second (cps). Sliding the bar to the left slows the repeat rate, and sliding the bar
to the right increases the repeat rate.
4.11.2 Backlight
• In the Keyboard Properties dialog box, open the Backlight tab.
Intensity
This parameter is used to adjust the light intensity of the VH10 keyboard backlight. Sliding the bar to the
left lowers the keyboard backlight intensity, and sliding it to the right increases the intensity. The backlight
automatically turns off when the computer is on UPS battery.
On For
The value chosen from this drop-down menu determines the duration of time that the keyboard backlight
stays on when a unit is not in use.
4.11.3 One Shot Modes
• In the Keyboard Properties dialog box, open the One Shots tab.
Note: Use the field at the bottom of this dialog box to test the repeat delay and rate settings
you’ve chosen.
Note: The keyboard backlight maximum brightness will decrease over time as it ages. Use mid-range
intensity settings when possible to extend the backlight lifespan. When the backlight starts to dim,
use this parameter to make it brighter.
Note: Tapping in the check box next to ‘When using external power, keep the backlight always ON’
forces the backlight to remain on when the unit is operating with external power.
To maximize battery run time when the VH10 is on UPS Battery Power, the keyboard backlight
automatically turns off. For details see “Power Saving Suspend” on page 70.
