How do u turn off backlight during a call

[djfreeze]

When using my bluetooth, my phone(samsung moment) stays lit the whole time. I'm trying to see is there a simple way to cut off the backlight to conserve battery power.....

Don't know cause I don't use bluetooth, but the screen timeout default is set to 1 minute. Changing it to 30 seconds might do the trick.

Is there a way to cut off the screen MANUALLY during a call?
