Entering the Security Code

Understanding the Security Code

The exclusive programmable security code feature built into your ET-400 
will prevent unauthorized use of your phone line.  Each time you press 
TALK PUSH HANG-UP, your personally selected security code is automatically 
transmitted from the Handset to the Base Unit.  The Base Unit compares the 
code from the Handset with its security code.  If the two codes are the 
same, you may proceed with the call; if they are not the same, the Handset 
will sound an error siganl and the TALK indicator will go off.  Once you 
have entered the security code, the above "verification" procedure takes 
place automatically each time you press TALK PUSH HANG-UP.

To Enter the Code

(1) With the Handset turned on, press the CODE ENTER button on the back of 
the Base Unit.  You will hear a short tone from the Handset and its TALK 
indicator will light.
(2) Enter any four-digit number on the Handset keypad.  (Use 0-9 keys only.)
The TALK indicator will go off and you will hear another short tone.

Your security code has now been entered inthe Handset and the Base Unit.

Security Code Hints

* A memory protection circuit in the Base Unit holds the memory for 2-1/2 
hours after the Base unit is unplugged.  The security code will be lost, 
and must be re-entered, if you allow the Handset battery pack to discharge 
completely or if you unplug the Base Unit for over 2-1/2 hours.  If the 
code is lost, you will hear the error signal when you press TALK PUSH HANG-
UP.
* The security code prevents other cordless telephones from initiating or 
answering a call on your phone line.  It does not prevent other radio units
on the same frequency from inadvertently hearing your conversation or 
causing interference on your ET-400; this can happen with any cordless 
telephone.
