LOCKING/UNLOCKING THE PHONE

Your phone has a simple security system. It can be locked
by using a four-digit lock code to prevent unauthorized use.
If you forget your lock code, you can change it in MENU 11
(accessible only by a shortcut). The factory default lock
code is 1234. The factory default security code is 12345.
When the phone is locked, only emergency calls (911,
*911) and calls to the number in memory location 98 can
be made, but any call can be received. Use of the memory
is also prevented (you cannot store or recall numbers).
³ Press MENU 0. The display will read LOCKCODE?.
· Key in your four-digit code. It will appear on the display
as a series of stars.
» Press STO.
If you make a mistake, the phone will display a CODE
ERROR message. To retry, start again from the beginning.
If you key the correct code, LOCKED will appear on the
display and remain there to remind you that the phone is
locked.
