4.6 LOW-CUT filter
To set the LOW-CUT filter,
press the ALERT and EVAC keys simultaneously and hold them down for more
than 3 seconds
. When the
RUN/SET
LED stops flashing and remains steady ON, release the keys.
Press the RESET/ACK. key. The LEDs will indicate the current settings:
AUX
LED ON =
filter ON
P.T.T.
LED ON =
filter OFF
Holding the
RESET/ACK
key down, press
AUX
to activate the filter or
P.T.T.
to de-activate it.
To leave the settings mode and save the changes made, press the
ALERT
and
EVAC
keys again. The
RUN/SET
LED will start flashing again. If you do NOT want to save the changes made, simply wait for the timeout (about 10
seconds), after which the previous settings will be restored.
Note: To check the effects of the changes described under points 4.3 to 4.6 above, a normal call so as to
listen to your own voice is recommended.
Note for INSTALLERS:
While installing and configuring the system, it may be necessary to mute the failure signalling buzzer temporarily.
To do this, there is a switch (
11
) on the rear panel, which has to be positioned with a small screwdriver. Remember
to re-activate the buzzer after completing the operations.
4.5 Output level
To set the output level,
press the ALERT and EVAC keys simultaneously and hold them down for more than
3 seconds
. When the
RUN/SET
LED stops flashing and remains steady ON, release the keys. Holding the
ALERT
key down, press
AUX
to increase the output level or
P.T.T.
to decrease it.
The appropriate LEDs will flash to indicate that the adjustment is being made. Once the (minimum or maximum)
limits have been reached, the LEDs will remain steady ON. To leave the settings mode and save the changes made,
press the
ALERT
and
EVAC
keys again. If you do NOT want to save the changes made, simply wait for the timeout
(about 10 seconds), after which the previous settings will be restored.
