Tuning in to Alternative Frequency (AF)
stations

There are programs transmitted at different frequencies
in different areas. Along with the program itself, an RDS
station sends the AF list data that contains the frequencies
sending the same program. If the signal of the tuned-in
frequency becomes weak while you are driving, the unit
automatically searches the same program sent at another
stronger frequency according to the AF list, so that you
do not have to seek and tune in to the other frequency
again.

1 Press AF during FM reception to activate AF function.

“AF” appears on the display.*
* “AF” flashes when the unit cannot receive AF list

data.

Tuning in to an EON*, Traffic Program (TP)

The unit automatically switches to FM reception and
tunes in to an EON, traffic announcement program when
the program starts.
* EON: Enhanced Other Network

1 Press TA during FM reception to activate TP function.

“TP” appears on the display.*
During reception, “TA” appears on the display.

* “TP” flashes when the unit cannot receive TP data.
To turn off TP function, press TA.
“TP” disappears.

Setting the volume of TP reception

When TP function is activated, the traffic announcement
program is tuned in at the volume set in the following
procedure regardless of the volume of the other source
at the time TP function is activated.

1 Press and hold AF until “BOOST 40” appears on the

display.
“BOOST 40” disappears approx. 5 seconds later.

2 Turn AUDIO CONTROL to select a volume level (0

to 80 in increments of 5).

3 Press SEL.

Activating AF function and TP function at the
same time

1 Press AF, and then press TA.

“AF” and “TP” appears on the display.

Notes

• During MW or LW reception, the unit will not
automatically tune in to a traffic announcement
program. Be sure to select “F1/2/3,” “TAPE,” or “AUX
IN” to activate TP function.

• When the unit tunes in to a traffic announcement
program by way of TP function, you can increase the
volume, but cannot decrease it.

•When the traffic announcement program finishes, the
unit automatically returns to the previous state.

Tuning in to a station by specifying a
Program Type (PTY)

1 Press and hold TA until “PRO-TYPE” appears on

the display.
“PRO-TYPE” disappears approx. 5 seconds later.

2 While “PRO-TYPE” is displayed, press one of the

preset station buttons* for more than 0.5 seconds to

Adjusting the clock by Clock Time (CT)
service

The unit adjusts the clock automatically according to the
CT data sent from a currently tuned-in RDS station.

1 Press and hold TA, and then press AF during FM

reception.
“CT” appears in the display.

2 Turn AUDIO CONTROL to select “CT ON.”

“CT” appears in the display and the clock is adjusted.

• The clock may not always be correct even when CT
function is on.

Tips and other information

Presetting Alternative Frequency (AF) stations
automatically

Only the strongest frequencies among the AF stations
that are broadcasting the same program are selected
and assigned to each preset station button.

1 During FM reception, make sure that “AF” and/or

“TP” appear(s) in the display (see “Tuning in to
Alternative Frequency (AF) stations” and “Tuning in
to an EON Traffic Program (TP)”).

2 Press and hold PS/A.ME until Auto Memory for AF

stations starts.

Displaying a Program Service (PS) name

You can check the name of currently tuned-in station in
the display. When the unit is tuned in to an RDS station
sending PS data, the station name appears in the
display.

Note

In the following cases, the station name will not appear
in the display:
— The tuned-in signal is too weak to activate this function.
— The tuned-in station is not sending PS data.

Notes on emergency broadcasts

• The unit automatically switches to FM reception and
tunes in to emergency broadcast when it starts. When
the broadcast finishes, the unit automatically returns
to the previous state.

•Be sure to turn on AF function and TP function to
receive emergency broadcasts.

• During MW or LW reception, the unit will not tune in
to the urgent broadcast.

CONNECTIONS

PRECAUTIONS

Precaution on making connections

Before connecting, make sure that the ignition switch is
set to OFF, and remove the earth terminal of the battery
to protect the unit and your car from damage.

Caution

Make the connections correctly, as illustrated in the
connection diagram.
Do not connect the negative ( cord of each speaker

10A

wire to a common point. When replacing the fuse, be
sure to use a fuse of the same rated amperage. Use
of a fuse of a higher rating may cause serious
damage to the unit.

CONNECTION DIAGRAM → A

Notes

• Use speakers with an impedance of 4 to 8 ohms and
with adequate power-handling capacities. Otherwise,
the speakers may be damaged.

• Do NOT connect the speakers in parallel.

• Do NOT connect the terminals of the speaker system to
the car chassis.

E To the radio mute lead of the cellular phone

hands-free car kit, etc.

When the telephone mute lead (light blue) is connected to
a cellular phone hands-free car kit, etc., the unit mutes the
sound from the speakers automatically during your
conversation on the cellular phone. For details, refer to the
instruction manual for the cellular phone hand-free car kit.

Note

This telephone mute lead supports connection only to the
radio mute line. When connected to another type of
output system, it will not work.

CONEXIONES

PRECAUCIONES

Precauciones al hacer las conexiones

Antes de conectar, confirme que el interruptor de encendido
está en OFF y desmonte el terminal a tierra de la batería
para proteger el aparato y su coche contra daños.

Precaución

Haga las conexiones correctamente, tal como se
describe en el diagrama de conexiones.
No conecte el cable negativo ( de cada cable de altavoz
a un punto común. Cuando cambie el fusible, utilice siempre
uno del mismo amperaje nominal. El uso de un fusible de
mayor régimen puede provocar daños importantes en el
aparato.

CONNEXIONS

PRECAUTIONS

Précautions pour les connexions

Avant le raccordement, vérifiez que la clé d’allumage est
sur OFF, et débranchez la prise de terre de la batterie
pour protéger l’appareil et votre voiture des dommages.

Attention

Effectuez les connexions correctement, comme
indiqué sur le diagramme de connexion.
Ne raccordez pas le cordon négatif ( de chaque fil
de haut-parleur à un point commun. Au remplacement
du fusible, utilisez un fusible à ampérage nominal
identique. L’emploi d’un fusible à ampérage plus
élevé peut sérieusement endommager l’appareil.
