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

Code

This button allows you to set a new lock

code.

To change the lock code:

Tap the Change Lock Code button.

Enter your existing lock code (the last
four digits of your phone number
unless you have changed it) in the
field and tap OK.

Enter a new lock code and tap OK.

Enter your new lock code again for
confirmation and tap OK.

Tap OK.

Lock Modem Now This field allows you to enable the Lock

Code feature immediately. (If you select on

power up in the previously described drop-

down menu, you need to close Watcher

before the lock code comes into effect.)

When you tap the button, Watcher prompts,

“Lock the modem now?”. Tap Yes at this

prompt to lock the AirCard.
