Nokia E63 - Manual (Page 102)

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
To prevent access to the contents of your device, lock the
device when in 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.
To change the lock code, select
Menu > Tools > Settings >
General > Security > Phone and SIM card > 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 Menu > Tools >
Settings > General > Security > Phone and SIM card >
Allow remote lock > Yes . Enter the remote lock message
and confirm the message. The message must be at least 5
characters long.
Memory
There are two types of memory into which you can save data
or install applications: device memory and memory card.
Free memory
To see how much memory is currently in use, how much free
memory remains, and how much memory is consumed by
each data type, select Menu > Options > Memory
details > Phone memory or Memory card .
Tip: To ensure that you have adequate memory,
transfer data regularly to a memory card or computer
or use File manager to delete files you no longer need.
After you install applications to a compatible memory card,
installation files (.sis, .sisx) remain in the device memory. The
files may use large amounts of memory and prevent you from
storing other files. To maintain sufficient memory, use Nokia
PC Suite to back up installation files to a compatible PC, then
use the file manager to remove the installation files from the
device memory. If the .sis file is a message attachment, delete
the message from the Messaging inbox.
