LEVEL 2 PASSWORD
If you wish to protect the
SETUP
menu only, activate/set the
LEV 2
password using the same
procedure as outlined above, ensuring that
SET PASSWORD LEV 2
is selected at step 1).
Once a level 2 password is activated, each time someone attempts to access the
SETUP
menu,
they will receive an
Insert PASSWORD
message asking for the level 2 password to be entered.
The
VIEW
menu will remain accessible at all times.
- SET ALARM setting
As previously explained, if a parameter falls outside a given value for a specific period of time
(for example: modulation 6 dB lower than the nominal value for more than 10 minutes), the
ON
LED will light up in red and the bottom part of the display will indicate the associated
alarm (e.g.,
Mpx Low
= insufficient modulation). The last 100 alarm events can be accessed
via the
VIEW LOG
alarm history menu, under the main
VIEW
menu.
This menu allows you to activate/deactivate each diagnostic alarm, and to set its sensitivity
level and the time period beyond which the alarm is activated. In addition, the
RESET LOG
function is available, which allows you to delete the alarm history saved.
The following alarms can be set:
•
LOW RF POW
– an alarm is issued when the RF power is detected at below a certain
percentage value.
•
HIGH VSWR
– an alarm is issued when an excessive SWR (standing wave ratio) is detected.
•
UNLOCK
– an alarm is issued when the internal PLL frequency synthesizer is unlocked.
•
MPX
– an alarm is issued when low (or no) modulation is detected for a given period of
time.
In general, to set alarms:
1) Turn the knob to select the alarm that you wish to activate/configure (e.g.,
LOW RF POW
),
then press to confirm.
