Operating Instructions

Sleep mode
Sleep mode saves battery power by putting HTC Thunderbolt into a low
power state while the display is off. It also stops accidental button presses
when HTC Thunderbolt is in your bag. You’ll still receive messages and calls
though, and missed calls and messages appear on the lock screen.
To prevent missed calls or messages from appearing on the lock
screen, press and then tap Settings > Privacy.
Switching to Sleep mode
Briefly press the POWER button to turn off the display and switch to Sleep
mode. HTC Thunderbolt also automatically goes into Sleep mode when it’s
idle for a while.
Waking up from Sleep mode
To wake HTC Thunderbolt up manually, press the POWER button. You’ll
need to unlock the screen.
HTC Thunderbolt automatically wakes up when you have an
incoming call.
Unlocking the screen
Pull the ring up to unlock the screen.
