Changing the Backlight Intensity
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 choose a high, medium, or low intensity, or turn the
backlight off entirely.
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 the Backlight On intensity and the
Backlight Idle intensity will decrease proportionally.
If you have attached any expansion modules and you find the backlight levels
between them and your phone are incompatible, you can modify the
maximum backlight intensity for each unit individually to match all backlights
to an overall consistent level. Refer to step 8 below for details.
The backlight automatically turns on with any button, soft key, hookswitch,
USB, or telephony activity. After 20 seconds of inactivity, the backlight dims
to its idle intensity.
