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 select a Program Type. The unit starts to search for a station of the selected Program Type and tunes in to the station.

* The Program Types are assigned to the preset station

buttons as follows:

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.

To turn off CT function, select “CT OFF” in step 2.

Notes

• In the following cases, “CT” flashes and the clock will not be adjusted: — The tuned-in signal is too weak to activate this

function.

— The tuned-in station is not sending CT data.

• 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.

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.

A De l’antenne du véhicule B A la prise d’entrée de l’amplificateur de

puissance en option (pour le canal arrière) Au connecteur ISO du véhicule (alimentation)

Vérifiez que l’agencement des broches du connecteur d’alimentation du véhicule est conforme à celle du connecteur ISO standard C-1. Certains types de voiture peuvent avoir un agencement de broches

Remarques

•Utilisez des enceintes à impédance de 4 à 8 ohms et puissance nominale adéquate. Sinon elles seront endommagées.

• Ne raccordez PAS les enceintes en parallèle.

• Ne raccordez PAS les prises du système d’enceintes au châssis de la voiture.

E Au conducteur d’assourdissement radio

du kit téléphone cellulaire auto mains libres

Quand le conducteur d’assourdissement radio (bleu ciel) est relié à un kit téléphone cellulaire auto mains libres, etc., l’appareil assourdit automatiquement le son des enceintes pendant la conversation au téléphone cellulaire. Pour les détails, consultez le mode d’emploi du kit téléphone cellulaire auto mains libres.

ANSCHLÜSSE

VORSICHTSMASSREGELN

Vorsichtsmaßregel zur Herstellung von Anschlüssen

Vor dem Herstellen von Anschlüssen sicherstellen, daß der Zündschalter auf OFF steht und die Masseklemme der Batterie entfernen, um das Gerät und das Fahrzeug vor Schäden zu schützen.

Vorsicht

Die Verbindungen korrekt herstellen, wie im Anschlußdiagramm gezeigt. Nicht die negative ( Leitung jedes Lautsprecherkabels an einen gemeinsamen Punkt anschließen. Beim Austauschen der Sicherung immer eine Sicherung der gleichen Stärke verwenden. Verwendung einer höheren Sicherung kann zu schweren Schäden am Gerät führen.

ANSCHLUSSDIAGRAMM → A

A Von der Autoantenne B Verstärkerendstufe (für hinteren Kanal) C Zum ISO-Anschluß des Fahrzeug

(Betriebsstromversorgung)

Stellen Sie sicher, daß die Pinanordnung der Betriebsstrombuchse des Fahrzeugs der Standard-ISOBuchse C-1 entspricht. Bestimmte Fahrzeugtypen können eine andere Pinanordnung haben, C-2 oder C-3. In diesem Fall ändern Sie die Verbindungen der roten und gelben Leitungen wie in C-2 oder C-3 gezeigt.

Hinweis

Wenn Ihr Fahrzeug nicht bereits mit ISOStandardbuchsen ausgestattet ist, sollten Sie einen Adapter verwenden, der von Ihrem Fachhändler oder einem guten Automobilzubehörgeschäft erhältlich ist.

Diese Leitung wird nicht für ein Fahrzeug mit manueller Antenne oder einer schalterbetriebenen Motorantenne verwendet. Wenn Sie die optionale Verstärkerendstufe mit dem Gerät verwenden wollen, diese Leitung an die Fernbedienungsklemme des Verstärker anschließen.) (Max. Versorgungsstrom 0,1 A)
