Changing the Backlight
The backlight is available only on the SoundPoint IP 335.
You can adjust your phone’s backlight by doing the following:
• Changing the brightness of the backlight.
• Changing the backlight timeout.
Changing the Backlight Brightness
The backlight brightness – or backlight intensity – has three components:
• Backlight On Intensity—The brightness of the screen when you press a key, have an incoming call,
end or hold a call, or another party resumes a call. You can set it to high, medium, or low.
• Backlight Idle Intensity—The brightness of the screen after the phone has been idle for a certain
number of seconds (as defined by the backlight timeout). You can set it to high, medium, or low.
• Maximum Intensity—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 do not press any keys on the phone, after 20 seconds of the backlight turning on (the default
backlight timeout), the backlight changes to the Backlight Idle Intensity. If one of the following phone
events is taking place, the backlight changes to Medium:
• A call is in progress
• A call is on hold
• There is an incoming call (ringing)
• There is an outgoing call (ringing back)
• Any menu shows on the display
To modify the backlight intensity:
1 Press the Menu key.
2 Select Settings > Basic > Backlight Intensity.
