To modify the backlight intensity | Polycom IP 450 manual

Customizing Your Phone

•Backlight On Intensity—the brightness of the screen when you press a key, have an incoming call, end or hold a call, or a call is resumed by the another party. You can set a high, medium, or low level.

•Backlight Idle Intensity—the brightness of the screen after the phone has been idle for a certain number of seconds (as defined by the backlight timeout). You can set a high, medium, or low level.

•Maximum Intensity—the entire backlight intensity scale. For example, if you decrease the Maximum Intensity, the Low, Medium, and High values for the Backlight On Intensity and the Backlight Idle Intensity will decrease proportionally.

If you do not press any keys on the phone, after 20 seconds of the backlight turning on (the default backlight timeout), the backlight changes to the Backlight Idle Intensity. If one of the following phone events is taking place, the backlight changes to medium:

•A call is in progress

•A call is on hold

•There is an incoming call (ringing)

•There is an outgoing call (ringing back)

•Any menu shows on the display
