86A - 7V2 MR-372-J84-86A000$297_eng.mif
RADIO
Anti-theft code
The radio is protected by a four digit code. This code
must be entered via the control satellite or the radio
keypad each time the battery is disconnected.
Entering the code with the control on the steering
wheel:
Press the lower button on the control to confirm an
entry.
Entry via the radio:
Enter the digits using buttons 1, 2, 3 and 4, and then
confirm with button 6.
If the code is entered incorrectly, the radio will be
locked (1 minute for the first error, 2 minutes for the
second error, 4 minutes for the third error, etc.
32 minutes maximum).
Some configurations must be set after the code has
been entered for the first time (see the Configuration
Section). These settings are stored when the battery is
disconnected.Reminder:
The radio will operate for approximately 2 minutes in
scrambled mode without the code having been entered
(with regular warning beeps).
If the vehicle is equipped with a CD changer in the
front panel, a code is exchanged between the CD
changer and the radio.
–If a new CD changer is fitted, the radio code is
programmed when the battery or CD changer is
connected.
–If the radio is replaced, enter the security code of the
old radio connected to the CD changer. The CD
changer is programmed with the code for the new
radio.
–If the old radio code is lost, the changer code can be
cleared using the clearing code. The clearing code is
issued by the Techline, server, etc.
Note:
If there is a configuration error, you can return to scrambled mode by pressing the 2 and 5 buttons at the same
time as switching the power on. Then wait 2 minutes.
Note:
The CD changer is supplied uncoded. When it is installed in the vehicle, the CD changer is programmed with the
radio supply code.
Reminder:
The radio will operate for approximately 2 minutes in scrambled mode without the code having been entered (with
regular warning beeps).
IMPORTANT
If the vehicle is fitted with a top of the range navigation system (ITS), enter the radio code in the following
way:
1. switch on the system by activating the vehicle's + after ignition feed,
2. wait 2 minutes: scrambled mode with beeps from the speakers, then code request screen appears,
3. enter the radio code using the ITS keypad: move the cursor with the central control and press to confirm.
4. switch off the ignition.

Self-test procedure

RADIO
Self-test procedure
The self-test procedure mode of the previous generation radios (PN0-6) allows certain main functions to be tested:
●by pressing buttons 2 and 4 at the same time, the speakers can be tested. They are supplied one by one; the
display enables the connections and signals from each speaker to be checked,
●by pressing buttons 1 and 6 at the same time, the reception level can be tested (after frequency is displayed),
–9 or letter: good reception,
–less than 3: poor reception,
–if 2: total loss of stereo.
The self-test procedure mode of the new generation radios (NR4/5) enables certain main functions to be tested
using the combination of buttons 1, 6 and i. The messages will be displayed in the following way:
●Radio pre-code displays one letter and 3 digits to avoid removal of the radio,
●speaker test with two bleeps (bass - treble) from the speakers, with the tested speakers shown on the display
(front left-hand H01, front right-hand H02, rear right-hand H03, rear left-hand H04),
●displays the frequencies and levels of the tuner sensors,
●software version displayed, displays fault finding for the connected aerial if the aerial is supplied by a coaxial
cable; in this case, the display shows H15 with X = 0, 1 or 2 depending on the aerial status (0: open circuit, 1:
short circuit to earth, 2: power consumption),
●audio test loudness OFF (H08), cuts any loudness for an audio test.
Note:
Also displays source use time and total time in 10 minute slots (Tuner (H09)/CD (H10)/cassette (H11)/CD changer
(H12)/auxiliary (13)/MP (H14)/Total (H15)).

ALP 7 The volume does not increase with the vehicle speed.
The SDVC (speed-dependent volume
control) function does not work.
Check the audio equipment
configuration (Expert mode). Set the
SPEED curve to 5 and run a test when
driving at a speed greater than 48 mph
(80 km/h).
No
Does the volume change?
Yes
The fault has been rectified. Check the signal on
connection 47F (see wiring
diagrams Technical Note,
vehicle, code 261) using a
multimeter. The voltage should
vary depending on vehicle
speed. Reset the control to: CURVE 2.
Yes
No
Does the signal increase?
YES
The fault is not associated with
the audio equipment. See MR
