Backlight intensity on the SoundPoint IP 650 phone has three components:
• Backlight On
• Backlight Idle
• Maximum Intensity
You can modify the Backlight On intensity and the Backlight Idle intensity
separately. You can select high, medium, low, and off levels for both.
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.
If you have attached one or more SoundPoint IP Expansion Modules to your
SoundPoint IP 650 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
SoundPoint IP Backlit Expansion Module
The Backlight On intensity applies for the 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
• A USB device plugged in or unplugged
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
• There is an incoming call (ringing)
to return to the idle display.
