Device security
You can modify the security settings for the PIN code, automatic locking of the device, and changing of the SIM card. You can
also change the PIN code, PIN2 code, lock code, and barring password.
Avoid using codes that are similar to emergency numbers, such as 112, to prevent accidental dialling of the emergency
number.
Codes are shown as asterisks. When changing a code, enter the current code, and then the new code twice.
Defining device lock settings
Important: In offline profile you cannot make (or receive) any calls, or use other features that require GSM
network coverage. To make any calls, you must first activate the phone function by changing the profile. You may,
however, be able to make an emergency call in offline profile by pressing the power key on the cover of the device
and then entering the official emergency number. This can be done using the cover phone interface only, not the
communicator interface. If the device has been locked, enter the lock code to activate the phone function. When the
device is locked, calls may still be possible to the official emergency number.
Making an emergency call in offline profile or when the device is locked requires that the device recognizes the
number to be an official emergency number. It may be advisable to change the profile or unlock the device by
entering the lock code before you make the emergency call.
To define device lock settings, select Security → Device security, and select the Device lock page.
Define the following:
• Autolock period—You can set a time-out after which the device is automatically locked and can be used only if the correct
lock code is entered. When the device is locked, calls may still be possible to the official emergency number programmed
into your device. You can also answer incoming calls.
• Lock code—Press Change to change the lock code. The new code must be 5 to 10 digits long. The preset code is 12345. To
avoid unauthorized use of your device, change the lock code. Keep the new code secret and in a safe place separate from
your device.
• Lock if SIM card is changed—You can set the device to ask for the lock code when an unknown SIM card is inserted into
your device. The device maintains a list of SIM cards that are recognized as the owner's cards.
• Allow remote locking—If you set this option to Yes, you can lock the device by sending a predefined text message from
another phone.
To create a remote locking message, select Security → Device security. Set the option Allow remote locking to Yes, enter your
lock code, and enter text for the remote locking message in the Message field. Confirm the message, and press Done. The
remote locking message is case-sensitive and can be 5 to 20 characters or digits long. Press Reboot to restart the device and
for the changes to take effect.
Tip: If you use a memory card with no password, the memory card will be locked when you lock your device with
the remote locking message. To remove the memory card password, select Desk → Office → File manager, press
Menu, and select Memory card → Security → Remove password.... Enter the remote locking message as your
password, and press Remove. If the remote locking message is longer than 8 characters, the first 8 characters of the
message are used as the memory card password.
Defining PIN code settings
To define PIN code settings, select Security → Device security, and select the PIN codes page.
Define the following:
• PIN code request—If you set this option to On, the PIN code is requested each time the phone is switched on. Note that
this setting cannot be changed if the phone is switched off or if there is no valid SIM card inserted. Note also that some
SIM cards do not allow you to turn off the PIN code request.
• PIN code—Press Change to change the PIN code. The PIN code must be 4 to 8 digits long. Changing the PIN code requires
that PIN code request is selected, the device is on, and that there is a valid SIM card inserted.
• PIN2 code—Press Change to change the PIN2 code. The PIN2 code must be 4 to 8 digits long. The PIN2 code is required to
access some functions, such as the fixed dialing settings, which must be supported by your SIM card.
Changing the barring password
To change the password used for barring voice, fax, and data calls, select Security → Device security, and select the Call
barring page. Select the Barring password field, and press Change. Enter the current code, and then the new code twice. The
barring password must be four digits long.
Certificate manager
Important: Note that even if the use of certificates makes the risks involved in remote connections and software
installation considerably smaller, they must be used correctly in order to benefit from increased security. The
