BenQ Z2 - Manual (Page 23)

Preparing Your Phone For Use 7
Turning the Phone On
1. Long-press to turn the phone on. The phone will show the
welcome display and play the welcome melody.
In this user manual, "long-press" means to press and hold down a key
for about two seconds before release. "Press" means to press a key
and release immediately
2. Enter your PIN1 number and press OK to confirm.
The PIN (Personal Identification Number) is the password provided
by your network operator. You need this password in order to use the
SIM card.
3. When the PIN code entered has been accepted, the phone will
automatically search for the designated network. This search process
may take a few seconds.
To set a welcome display and melody, go to: Settings > Display >
Welcome Message. For details, please refer to page 112.
If you enter the PIN incorrectly three times in a row, the SIM card will
be locked. You must now enter the PUK (Personal Unblocking Key)
for that SIM card in order to unlock it. Please contact your network
operator to obtain a PUK.
To activate/disable PIN password authentication, go to Settings >
Security > PIN Code > PIN 1 Code > Set Status. See page 120.
