6. COMMANDS AND PROGRAMMING
The transmitter allows exhaustive control of all transmission parameters and complete programmability
and monitoring facilities through the various software controls via the front panel keyboard and display. The
same functions are remotely addressable with a proper software, which is not included as a standard option.
For a description of remote capability see the proper section on the manual. In this section we will examine
the front panel menu-driven operational capability.
6.1 PASSWORD ORGANIZATION
The password organisation is set in 3 security levels, each having its own password. An higher level
permits to change also the lower levels authorisations and passwords.
Each password is composed by 4 alphanumeric characters, including extended capital and lower case
ones and several special symbols. We suggest using a wide range of characters as the security level raises,
so as to increase the possible combinations. No password is ever shown: it is always masked by dummy
characters as "...." or "****". Nevertheless it may be always changed with the higher level authorisation.
Here is the purpose of each level:
Level 1: Lower security level.
It is needed to access to most of the monitoring and control menu fields,
not permitting to alter or programming any operating parameter. It is factory pre-set to "off" state
by default, enabling the user navigation through the transmitter's monitoring menu information.
AEV S.P.A. suggest leaving it in its state if a high privacy level is not needed.
If set to "on" it will show the default menu field #00 (c.r. menu tree), requiring password for any
other information or pre-set. Failure to insert a correct password of any level will prohibit any
other access to the commands for the time-out length (usually 3 minutes).
No change of the functioning mode is done in case of incorrect password input. No information
is available on the display regarding the transmitter functioning.
Level 2:Service level
. This password is needed for any functioning set-up as frequency and power,
sensitivities, clock and date etc. Its use is reserved to service technicians who need a wide access
to the transmitter presets and functions.
While the default factory state is "off", AEV S.P.A. suggests changing the default state and
password immediately at the first power on, to prevent unauthorised people from tampering with
the transmitter commands, if the default word is known or the state is set to "off".
