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.
Leitungsfarben
1 Schwarz (Masseleitung zum Anschluß an die
Fahrzeugkarosserie [Metall].)
Blau (Motorantennenleitung zum Anschluß an die Klemme

des Relaisschalters für ein Fahrzeug, das mit
vollautomatischer Motorantenne ausgestattet 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.)

Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/
specified.
• C : panel designation.
