 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:
1change user level
2edit password
Selecting <1change user level> brings
up the restriction menu:
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.
