DISPLAYING YOUR TELEPHONE NUMBER

Your telephone number is permanently stored in memory location 31.  You can
display the number by pressing [SEL] [RCL] [3] [1] or [3] [1] [SEL] [RCL].

LOCKING THE PHONE

You can lock the CT-103 to prevent unauthorized outgoing calls.  When the
phone is locked, you can call only the number stored in memory location 30,
and emergency calls (911 and *911).

You can always receive calls, even while the phone is locked.

To lock the phone press [SEL] [LCK].  LCK appears on the display.  To
unlock the phone, enter the 4-digit code you selected when you purchased
the phone.  (The lock code is set to 1234 at the factory.)  LCK disappears
from the display.  If you enter an incorrect lock code, LCK remains on the
display.

NOTE:  If you have forgotten the lock code, you can also unlock the phone,
       entering the last four digits of your security code.

To call the number in memory location 30, use the short method of dialing [3] [0] [SND].  If you use the long method, the display shows.
