HTC One M9 - Manual (Page 186)

Restoring a nano SIM card that has been locked out
If you enter the wrong PIN more times than the maximum number of attempts allowed, the card
will become “PUK-locked.”
You need a Pin Unlock Key (PUK) code to restore access to HTC One M9. Contact your mobile
operator for this code.
1. On the Phone dialer screen, enter the PUK code, and then tap Next.
2. Enter the new PIN you want to use, and then tap Next.
3. Enter the new PIN again, and then tap OK.
Navigating HTC One M9 with TalkBack
Use TalkBack if you need to navigate HTC One M9 by spoken feedback. When you touch the screen,
HTC One M9 vibrates and gives you an audible response so you know what you are touching.
Not all languages are supported.
Turning TalkBack on
1. From the Home screen, tap > Settings > Accessibility.
2. Tap TalkBack, and then tap the On/Off switch.
3. Read the TalkBack disclaimer and then tap OK.
A short tutorial explaining how to use TalkBack will begin playing after you turn on TalkBack.
TalkBack works best if you turn off auto-rotate and enable Explore by touch.
