any signal from the LEDs or buzzer.
We use <previous random digits> and <following
random digits> to indicate the random number
sequences typed by the user before the <6 digit
user code>, and aer having pressed the asterisk key
 respecvely; the typing sequence with masking
code will therefore be the following:
<previous random digits>
<6 digit user code> *
<following random digits> *
If the <6 digit user code> is present in the memory
then the green LED LV lights up, at this point by
pressing a channel buon (provided that it matches
the stored user code) you can acvate the radio
transmission.
For example, to acvate the 6-digit code 
you can type the following sequence:
294862...308236057986…791964 *
and nally the channel keys     to acvate the
transmission.
NOTE: The numbers are irrelevant and not necessary.
Acvaon can be done by simply typing .

Any me the typed sequence is not correct the error
signal will be given, by eming 5 quick ashes of
the red LED LR, accompanied by the intermient
acvaon of the buzzer. An error signal can occur
for the following reasons:
• The entered number is not recognized (for
example, you typed an incorrect password or a
user code that is not present in the memory).
• You are trying to enter a code or password with
more than 6 digits or less than 3 digits.
• You typed the number too slowly.
• In the procedure for the deleon of a user code or
password change, if there is a dierence between
the rst number inserted and the conrmaon
number.
• If you are trying to store a code already present
in the memory
• If a begun sequence has not been completed; for
example, if you enter a code, but you do not press
the * character aer a few seconds the keypad
will signal an error message
• When running a storage or cancellaon operaon
and the # key is typed instead of the asterisk *.

If you enter an incorrect user code 5 consecuve
mes, the keyboard will start to ash the red and
green LEDs (LR and LV) in an alternang manner and
will then be locked for 20 seconds. Pressing the keys
will give you no message at all.

The loss of baery charge is indicated by the
simultaneous lighng up of the red and green LEDs
while typing the user code. You can sll perform a
radio transmission, but it is advisable to replace the
baeries.
If you connue to use the keyboard, it will be locked
denively: even if you key in the correct user code,
you will see the lockout signal (red and green LEDs
that ash alternately), and the radio transmission is
disabled.

CAUTION! Use baeries of the same brand; do not
mix new baeries with used baeries.
To replace the baeries, follow the following
sequence of operaons:
• Remove the side trims and unscrew the two
screws underneath to remove the keyboard from
the slot ( detail B).
• Remove the baery pack connector ( 

• Loosen the screw that secures the baery pack to
enable opening it ( detail E).
• Replace the baeries while ensuring the correct
polarity as indicated on the baery holder (
 detail C).
• Reinstall the baery pack and secure it with the
appropriate screw
• Reconnect the connector to the keyboard: at
this point the keyboard is presented as shown in
 detail F.
• Replace the keypad in its slot, secure it with the
screws and reinsert the trims

Verify that the acvaon of the radio transmission
acvates all the corresponding outputs on the
receivers.
Make sure that during the transmission, the red LED
ashes when the xed code transmission is set, or
