Backlight intensity on the SoundPoint IP 670 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 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
