Calibrate Screen (6739i only)
The “Calibrate Screen” option allows you to calibrate the color touchscreen. This process makes fine adjustments to the
color screen on the phone for optimal display purposes.
Calibrating the Screen
Background Image on Idle Screen
Administrators can brand the idle screen of the 6739i and 6867i IP phones with their own company logo or image. The
phones can now display a background image in the bottom layer of the idle screen. This image can be set by the new
“background image” parameter. Current text (i.e. screen name, extension, and date/time) and softkeys on the idle
screen are on top of the background image. The background image can be downloaded from your configuration server
using either tftp, ftp, http, and https protocols.
Idle Screen Image Requirements for the 6739i:
• 640 x 480 pixels
• 24-bit color depth
• Both .png and .jpg files are supported
• There should be no frame around the image
• Avoid using images with light-colored elements
