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.)
