10.4 Signal reception attenuator
If you are in an area where radio signals are too strong (e.g., near a high-powered repeater or transmitter), you may
find that these signals saturate your receiver, reducing performance. To avoid this situation, you can temporarily
insert an internal signal attenuator as follows:
1) Press the menu/

button to access the command menu, then use the buttons to highlight the
Radio Param
option.
2) Press menu/↵ to view the available sub-menus.
3) Press the
buttons repeatedly until the
Loc/Dist
(local/distant) sub-menu is highlighted. To its left, you will see a
D

4) Press menu/↵ to select
L
(local).
5) Exit the sub-menu by pressing the F4/E
SC
button, then press it a second time to exit the main menu and return to the standby
screen.
 In stand-by, the display will always show the current setting with the (distant = attenuator deactivated) or (local =
attenuator activated) icon.
 As soon as conditions return to normal (e.g., you have moved to an area where signals are not as strong), do not
forget to deactivate the attenator, otherwise you will not be able to receive weak signals.
To deactivate the attenuator, follow the procedure outlined above, selecting
D
at step 4.

F4/E
SC
button, then press it a second time to exit the main menu and return to the standby
screen.

otherwise you will not be able to use the repeater when it has been fixed.
10.6 Confidential transmission (optional scrambler board)
Your transceiver may be equipped with an optional internal scrambler board. This is a device that makes your
communication unintelligible by normal radio receivers/transceivers, but perfectly clear to other members of your
radio network, who will be equipped with a compatible scrambler board.

1) Ensure your receiving party has activated their scrambler.

buttons to highlight the
