PTRL NV/3 & RXRL NV/3
The system provides for three access levels, each with its own password. Each
password provides access to its matching level and to lower levels.
Each password is made up of 4 alphanumeric characters, including upper and lower
case characters and special symbols. R.V.R. recommends using an increasing variety
of characters for higher levels, as this increases the number of possible combinations.
Passwords are never displayed and are always masked using substitute characters
such as " " or "****". However, lower-level passwords may be changed after entering
a higher-level password. Outlined below are the access rights associated with each
security level:
Level 1: Lowest security level (where high security is required)
It provides access to most control menu screen pages, but does not enable changes
to operating parameters. It is set to "OFF" at the factory, meaning that the system will
not prompt for a password so as to allow free access to and navigation of the control
menu.
R.V.R. recommends that this default setting be left unchanged, unless user wants to
restrict viewing of operating parameters to authorised personnel. When this level is
set to "ON", the default menu field #00 (see menu tree), is shown and the system will
prompt for a password before displaying any additional data or settings. In the event
the correct password is not entered for any one of the three levels, further access to
controls will be inhibited for a preset time (time-out), typically 3 minutes. Entering the
wrong password will not affect unit mode of operation. The display simply provides
no information on unit operation.
Level 2: Service level
In this level, the password is required to gain access to any operating parameter
settings, such as frequency, power, sensitivity, output levels, etc. This password is
restricted to service engineers who need unrestricted access to functions and
calibrations for servicing purposes. This password is not required to view modes
and operating parameters during operation.
Again, default factory setting is "OFF". R.V.R recommends changing both the
password and the configuration (if needed) soon after installation, to prevent tampering
with commands by unauthorised personnel.
Level 3: Highest security level and factory settings
This password is set to "ON" by default and - for safety reasons - will automatically
switch back to "ON" after the display timer times out, even when it is disabled. Access
to this password must be restricted to a
small group
of persons; as soon as you
have set this password, write it down and store it in a safe place.
