You can set the maximum bandwidth to use for a video call. The call rate you 

select applies to your next video call.

Tap  

> 

Settings > Basic > Call Rate.

From the Call Rate screen, tap the field’s highlighted grey box. From the 

drop-down list, tap the maximum call rate you want to use for video 

calls. (To scroll through all the call rates, press and drag the slider.)
You can choose a call rate between 128 kbps and 768 kbps. (The default 

setting is 768 kbps.)

Tap the Save soft key.

Tap 

 to return to the idle screen.

Your phone is set up with a power-saving mode that turns off the touch screen 

to conserve energy. Your phone enters power-saving mode after it has been 

idle for a certain period of time and its camera doesn’t detect motion. Your 

phone will not enter power-saving mode if it detects motion (for example, if 
you’re near the phone), even if the phone has been idle for the period of time 

you specified.
You can configure the period of time that the phone is idle (“idle timeout”) 

before the touch screen turns off (if the camera does not detect motion). You 

can configure different idle timeouts for office hours and off hours (evenings 

and weekends).
During off hours, the message “Off Hours Mode” scrolls on the status bar.
During power-saving mode, the LED on the top-right of the phone slow-blinks 

red to indicate that the phone has power and is ready to use, but is in 

power-saving mode. Your phone will exit power-saving mode if the camera 

detects motion or a phone event occurs (for example, an incoming call or 

message).

Note

Your system administrator can set a maximum call rate for video calls. If your 
system administrator sets a call rate limit, you will not be able to select a call rate 
above this limit.
