Backlight

Backlight determines the brightness of the touch screen display, allowing users to read easily in
dark environments. Backlight time specifies the delay time to turn off the backlight when the IP
phone is inactive. Backlight turns off quickly if a short backlight time is configured, this may not
give users enough time to read messages. Backlight time is applicable to SIP-T58V/T58A/T56A
IP phones and the connected EXP50.
You can configure the backlight time as one of the following types:
Always On: Backlight is turned on permanently.

15s, 30s, 60s, 120s, 300s, 600s or 1800s: Backlight is turned off when the IP phone is

inactive after a preset period of time (in seconds), but it is automatically turned on if the
status of the IP phone changes or any key is pressed.
Backlight Active Level is used to adjust the backlight intensity of the touch screen when the
phone is active. Backlight Active Level is applicable to SIP-T58V/T58A/T56A IP phones and the
connected EXP50.
