When a password is requested, it is entered as follows:

• Rotate and press the Select switch. A single beep sounds when the switch is pressed (if 

that option is selected)

Separate Download (write) and Upload (read) passwords can be programmed to prevent 
unauthorized downloading or uploading of radio programming parameters. When one or 
both of these passwords are used, the proper password must be entered to perform the 
operation. A “User” password is not required to upload or download parameters.

The Master Password overrides all the preceding passwords. It can be used by a system 
administrator as a “pass key” to a password controlled function or to change a lost or 
inadvertently changed password. Master passwords are set up and changed the same as the 
other passwords. It does not override the following Zone Password.

A zone password can be programmed with the Viking VM600 mobile. It prevents 
unauthorized reprogramming of zones by keypad programming.
