Backlight Intensity
Backlight intensity on the SoundPoint IP 650 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 650 and you find that the backlight levels between them are
incompatible, you can modify the maximum backlight intensity. This will
result in changing all Expansion Module backlights to an overall consistent
level. For more information, Using the SoundPoint IP Backlit Expansion
Module on page 5-1.
Dim mode intensity is determined by the Backlight On intensity and the
Backlight Idle intensity together as follows:
Backlight On Intensity Backlight Idle Intensity Dim Intensity
off off off
low dimmer than low low
medium dimmer than medium medium
high off medium
