Functioning of the keys and messages
The keys

along with the keys
*
and
#
allow
the activation of the change of password sequences,
the save/delete code, the full deletion of codes and
more. Four keys have a dual function since they are
also used to activate the radio broadcast:
• Key
1
/
A
: activation of the radio channel
CHA
• Key
4
/
B
: activation of the radio channel
CHB
• Key
7
/
C
: activation of the radio channel
CHC
• Key *
/
D
: activation of the radio channel
CHD
The
A,B,C,D
channel keys do not have a
predetermined function and can be stored on any
function of the radio receiver.
The keyboard has a green LED and a red one (see
Figure 1
, Detail
A
:
LV
and
LR,
respectively), and
a buzzer: these are used to give messages while
typing and during the various stages of operation.
During the radio broadcast:
- in fixed code mode the red LED flashes
- in "rolling code" mode the green LED flashes.

Installation
Before attaching the keyboard into the appropriate
slot:
• Connect the batteries to the keyboard connector
(see
Figure 6
details
D,
F
).
• Change the security password (see section 5.1
CHANGE PASSWORD); write down the new
password in an adequate and secure place. Upon
performing the password change you also enable
the transmission mode (fixed or "rolling" code).
CAUTION! A change of password is required
in order to maintain the level of security of the
installation, otherwise a code could be stored in
a fraudulent manner thus allowing an attacker to
activate radio commands using this fraudulent
code.
• Deleting saved user codes (see section 5.2
COMPLETE DELETION OF USER CODES).
• Storing at least one user code in the keyboard
memory (see paragraph 5.3 STORING A USER
CODE).
• Determine the maximum number of radio
functions you want to activate on the receiver
or receivers envisaged in the installation: this
determines the number of channel keys to be
enabled on the keyboard.

• Store the aforementioned keyboard channel keys
on the receiver (see paragraph 5.4 STORAGE ON
THE RECEIVER)
• Verify, when placing the keyboard, that the
intended installation point allows for the remote
operation of the receiver; if the placement
distance does not guarantee good transmission,
change the installation point or evaluate the
positioning of the receiver's antenna (or, if absent,
its installation)
After completing these operations you may now
