6.3.19. User Password
Settings are protected by a user password. The password consists of four digits. The PGR-
6150 leaves the factory with the password "5555" which can be changed by the user.
When a setting is modified, the PGR-6150-OPI requests the user password and initiates a
session if the correct password is entered. This session closes if no key is pressed for five
minutes.
When using communications, the user password field is requested in the settings confirmation
sections. If the password entered does not match the PGR-6150 password, the settings
changes are rejected.
