3. OPERATION

OPERATION

RPM4 is delivered with no active password and access to the User Level menu is open. The user level is set to <1Low>. User levels can be changed freely until a password has been created.

To access the LEVEL function press [SPECIAL], <5prefs>, <5level>. The display is:

Selecting <1change user level> brings up the restriction menu:

1change user level 2edit password

Restrictions: 1none 2low 3medium 4high

The cursor is on the current restriction level. Select a different level or or [ESC] back to the MAIN RUN screen.

If no password is active, selecting <2edit password> displays the user password and allows it to be edited.

Password: pppppp

0 disables password

Once a password has been entered, the user level cannot be changed without reentering the password.

Passwords can be up to six numbers in length and cannot start with a zero. If <0> is entered, the password is made inactive and the user will not be required to enter a password to access the user level menu. This condition, with a security level of <2low>, is the factory default.

If there is an active password, the RPM4 password entry screen appears. The user must enter the user defined password or the factory secondary password to proceed further:

RPM4 SNnnnn-xx Password: pppppp

The first field, <nnnn>, is the serial number of the RPM4, followed by a second field, <xx>, that represents the number of times that a secondary password has been used. The second field, <xx>, increments each time a secondary password is used. The third field, <pppppp> is for user entry of the normal password.

The factory secondary password is available in case the user’s password has been misplaced or forgotten. It can be obtained by contacting a DHI Authorized Service Center (see Table 29). The factory secondary password is different for all RPM4’s and changes each time it is used.
