Example: Setting a Custom Logo Display
The following example shows configuration for uploading a custom logo picture “logo.dob”, and then
setting it to display on the phone idle screen. The logo picture is customized and placed on the
provisioning server “192.168.10.25”.
Example
lcd_logo.url = http://192.168.10.25/logo.dob
phone_setting.lcd_logo.mode = 2
After provisioning, the phone displays the custom logo screen and the idle screen alternately.
