before system or channel parameters in that zone can be changed by keypad programming. 
The zone password is programmed. A different password can be programmed for each 
zone.

Ensure that the zone passwords are not lost because they cannot be overridden in the field.
When an attempt is made to select a system or channel parameter in a password protected 
zone, “Password” is flashed. The password is always eight digits long and is entered using 
the same procedure as used for the power-up password described below. After the 
password is entered, system and channel parameters for that zone can be reprogrammed 
normally.
When this feature is enabled, “Enter Pswd” is briefly displayed when power is turned on. 
The password can be 1-8 digits in length, and consists of digits 0-9. It is entered as 
follows. If an incorrect password is entered, “Incorrect” is displayed and it must be re-
entered. A password of 0 deactivates the feature.
