OPERATION
RPM4-AD 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-AD 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 34). The factory secondary password
is different for all RPM4’s and changes each time it is used.
