Auto Power Off

The Auto Power Off function automatically turns off power whenever

1 minute, 3 minutes, or 6 minutes before Auto Power Off is triggered
(page 174).

for about 15 seconds for easy viewing, even in the dark.
• Tapping the Light icon while the backlight is on turns it off.
• The backlight may fail to turn on when battery power is low and during data
communication.
