SETTING THE SECURITY LEVEL

The phone offers two levels of security protection.

    Directory Lock prevents anyone from changing or searching your
    directories.

    Dial Lock provides additional protection by restricting all outgoing
    calls except the three "single touch" memory keys

The system is protected by a 4-digit security code which must be used to
change the security level.

Even with the system locked, incoming calls are always received and "single
touch" memory keys are never locked.

Because the "     |     ","     ||     ", and"     |||     " keys always
remain active, be sure emergency numbers are stored before locking your
phone.

When the phone is not in use, press "     |||     " four times to display
the message SET SECURITY?

1.  Select YES and enter your present 4-digit security code.

    NOTE:  Initially, the code is set at 0000.

2.  Select DONE. If the code is incorrect, you cannot change the security
    level.

3.  Choose a level of security protection.

    Select OFF to unlock the system, allowing use of all features.

    Delete DIR to prevent any reviews or changes of the directories
    or"single touch" memory keys.

    Select ALL to prevent all dialing except of "single touch" memory
    numbers.

NOTE:  When either level of security has been set, the window displays the
       lock symbol.

CHANGING THE SECURITY CODE

When the phone is not in use, press"     |||     " five times to display
the message CHANGE CODE?

1.  Select YES and enter your present 4-digit security code.

    NOTE:  Initially, the code is set at 0000.

2.  Select DONE. If the old code is incorrect, you cannot change to a new
    code.

3.  Choose a new 4-digit security code.

4.  Select DONE when the new code is correct.

    NOTE:  Write down your security code in a special place. If you lock
           the system and forget the code, you must reset the phone and
           clear all names and numbers.

Operating Without Batteries or AC Power

If AC power is lost and the batteries are either dead or missing, your
phone will still operate.

    The LCD will display "NO AC POWER." Plug in your AC adapter as soon as
    possible.

    If the batteries are missing or completely dead, all memory will be
    lost.  This includes date & time, voice names, speed names, and your
    dial settings(pulse vs. tone). The phone will set to pulse dialing
    under this  condition. However, you can still temporarily switch to
    tone dialing by pressing the *or # keys.

    The following features will not operate without AC power or batteries:
    hold, mute, voice dialing, directory, call timer, redial. No features
    except ringing will work when the handset is hung up.

    The phone will not operate properly is another extension phone on the
    same line is already in use.
