Security
There are six types of security setting categories, and you
can optimize security mode by choosing sub menus in
“Security Setup” in “Settings” menu. These security settings
will help you to keep privacy and to prevent other people from
using the phone without your permission.
Please see details of security features. For basic key
protection, please see the following description of the keypad
lock function.
Keypad Lock
You have an option to lock the keypad of your phone to
protect from mistakenly pressed keys which may cause
malfunctions.
Press the
*
key to activate the keypad lock, and select the
key locking time from 5 seconds to 5 minutes. When the
Keypad Lock feature is enabled, you must press the [unlock]
soft key (right) and then press the Right soft key and # key-in
sequence, each time you need to release the keypad lock.
You may not make a call or operate the phone if unlock code
is not entered. However, answering a call and receiving
message are available without entering the unlocking key
sequence. (see Settings > Security Setup > Auto Keypad
Lock.)
