Changing the Backlight Intensity
Backlight intensity on the SoundPoint IP 670 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.
If you have attached one or more SoundPoint IP Expansion Modules to your
SoundPoint IP 670 and you find that the backlight levels between them are
incompatible, you can modify the maximum backlight intensity on a
unit-by-unit basis. This allows you to match all Expansion Module backlights
to an overall consistent level. For more information, refer to Using the
SoundPoint
®
IP Color Expansion Module on page 5-1.
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
