Alarm code
This device is equipped with a four-digit code to protect
against theft. This code must be inserted when prompted
by the Radio. The code request function is activated in
the factory.
NOTE: The code is indicated in the "radio pass" of your
truck radio. If you lose the code, please contact Tevva
Aftersales.
NOTE: Do not keep the radio password in the vehicle!
When Radio prompts password, the initial digits consist
of four *
To insert your own password:
•First digit: repeatedly press the station 1 pre-selection
button (9) until the display shows the first digit of its
own numeric code.
•Second digit: repeatedly press the station 2 pre-selec-
tion button (10) until the display shows the second digit
of its own numeric code.
•Third digit: repeatedly press the station 3 pre-selection
button (11) until the display shows the third digit of its
own numeric code.
•Fourth digit: repeatedly press the station 4 pre-selec-
tion button (12) until the display shows the fourth digit
of its own numeric code.
•
Brief press (1) to confirm the code.
If the password is correct, the Radio turns (ON) and al-
lows normal operation.
NOTE: If the entered password is incorrect, the
display will show the error ‘Wrong psw xx’ where xx is
the number of failed attempts. After that, the radio
automatically goes back to the “Enter passwd”
window, filling the password with “****”

11
NOTE: the attempt failed number is not cleared with
battery cut-off.
The protection mechanism intervenes in all phases of Ra-
dio operation in order to detect anomaly situations. Al-
though the Radio can always be used even with the vehi-
cle stationary and key set to OFF, when the key is subse-
quently inserted, the Radio, switched on previously, may
show the message ‘VIN ERROR’ and then automatically
switch off after a few seconds.
In this case the Radio needs to confirm the password for
the vehicle on which it is currently mounted and the fol-
lowing procedure must be implemented:
•Switch off the radio with a long press on the ON/OFF
button (1) .
•Switch off the vehicle (key OFF).
•Start the vehicle (key ON).
•The radio shows the password required screen.
•Enter the password in the 'radio pass' using the proce-
dure described above.
NOTE: As protection strategy against tampering,
after some failed attempts Radio waits some time
before enabling the prompt of the password. The
waiting time is related to the number of failed
attempts and follows the below table.
Number of incorrect
passwords entered
Wait time
12 s
230 s
3120 s
4600 s
51200 s
6 - 20 3600 s
>20 Permanent
ATTENTION: After 20 attempts, the Radio is no longer
recoverable.
NOTE: If the vehicle is switched off during password
input lock, the remaining timer is resumed the
following time the Radio turns on.
NOTE: If battery cut off happens during password
input lock, the following time that the Radio is switched
on, the waiting time restarts from the beginning. For
example: total waiting time is 600 s, remaining time is
300 s and the battery is then deactivated. The next
time that the Radio is switched on, the waiting time is
restored again to 600 s.
