Polycom SpectraLink 8400 Series Wireless Handset
Backlight timeout
The backlight LCD turns on when you press any key or when incoming activity occurs, and will turn off
after a selected period of either 5, 10, 15, or 30 seconds of inactivity. You can also disable the backlight
completely with this option.
To change the backlight timeout:
• From Settings > User Settings, select Backlight Timeout to change the amount of time that
elapses after a period of inactivity before the backlight turns off or to disable it completely.
Backlight Intensity
The handset's backlight helps you to see the screen. You can adjust the backlight for different lighting
conditions. Note that when the handset has been idle for a period of time, the backlight will turn off and
the handset will go into power-saving mode.
To change the backlight intensity:
• From Settings > User Settings, select Backlight Intensity on the Preferences menu to get to the
Backlight Intensity screen. Here you can adjust the Backlight On intensity, the Backlight Idle
intensity, and the Maximum Intensity.
When you modify the Maximum Intensity, you are modifying the entire Backlight intensity
scale. For example, if you decrease the Maximum Intensity, the low, medium, and high
values for both Backlight On intensity and the Backlight Idle intensity decrease.
