Security and data management
Manage the data and software on your device, and take
care of the security of the device and its contents.
Important: Your device can only support one
antivirus application. Having more than one application
with antivirus functionality could affect performance and
operation or cause the device to stop functioning.

Lock the device

Important: If the device has been locked, enter the
lock code to activate the phone function.
When the device is locked, calls may be possible to the
official emergency number. Making an emergency call in
the offline profile or when the device is locked requires
that the device recognise the number to be an official
emergency number. It is advisable to change the profile
or unlock the device by entering the lock code before you
make the emergency call.
To prevent access to the contents of your device, lock the
device when in the home screen. Press the power key,
select Lock phone, and enter your lock code. The default
lock code is 12345. To unlock, press the left selection key,
enter your lock code, and press the scroll key.
Select Menu > Control panel > Settings and General >
Security > Phone and SIM card.
To change the lock code, select Lock code. Enter the old
code and then the new code twice. The new code can be
4-255 characters long. Both alphabets and digits can be
used, and both uppercase and lowercase alphabets are
possible.
You can also lock the device remotely by sending a text
message to the device. To enable remote locking and to
define the text for the message, select Allow remote
lock > Yes. Enter the remote lock message and confirm
the message. The message must be at least 5 characters
long.

Memory card security

Select Menu > Office > File mgr..
You can protect a memory card with a password to prevent
unauthorised access. To set a password, select Options >
Memory card password > Set. The password can be up
to 8 characters long and is case-sensitive. The password is
stored in your device. You do not need to enter it again
while you use the memory card on the same device. If you
use the memory card on another device, you are asked for
the password. Not all memory cards support password
protection.
