Table 14-7: Security Tab Options

Field	Description
Lock modem	The Lock Code feature can be used to
	prevent others from using your AirCard and
	your account. When the Lock Code is
	enabled, you are prompted to enter a code
	any time Watcher is launched, and if the
	wrong code is entered, Watcher closes.
	(This makes it impossible to use the
	AirCard without knowing the lock code.) By
	default the lock code is the last four digits of
	your phone number.
	To disable the feature, select never from
	the drop-down menu. To enable the
	feature, so that you are prompted for a lock
	code the next time you launch Watcher,
	select on power up from the drop-down
	menu. (The Lock Code feature will then
	remain enabled until you disable it by
	selecting never in this field.)
Change Lock	This button allows you to set a new lock
Code	code.
	To change the lock code:
	1. Tap the Change Lock Code button.
	2. Enter your existing lock code (the last
	four digits of your phone number
	unless you have changed it) in the
	field and tap OK.
	3. Enter a new lock code and tap OK.
	4. Enter your new lock code again for
	confirmation and tap OK.
	5. Tap OK.
