Backlight Intensity
Backlight intensity on the SoundPoint IP 560 phone has three modes:
• Backlight On
• Backlight Idle
• Dim
You can modify the Backlight On intensity and the Backlight Idle intensity
separately. You can select high, medium, low, and off levels for both.
You can also modify the maximum backlight intensity.
Dim mode intensity is determined by the Backlight On intensity and the
Backlight Idle intensity together as follows:
The Backlight On mode turns on for following events:
• Any key press
• Hookswitch release
• Incoming calls
• Ending a call, holding a call, resuming a call by the other party
• A voice or instant message received
If you do not press any keys on the phone, after 20 seconds of the backlight
turning on, the backlight dims (or changes) to medium in the following cases:
• A call is in progress
• A call is on hold
