For cars supplied with standard ISO connectors, you can directly mount the car radio
(see ‘MOUNTING’). For cars with different connecting standards, your dealer can provide specific
adaptor cables for a problem free installation (see table on separate installation card).
If an adaptor cable is not in the table, you can prepare the connection yourself
(see ‘PREPARATION’). There is a high voltage inside the set! Do not open it to prevent an electric shock.
PREPARATION
The set must be connected to a 12 V car battery with negative terminal to earth (car chassis).
* To prevent short-circuiting, disconnect the negative car battery terminal until the
set has been mounted and connected (fig. 1). See separate installation card.
POWER SUPPLY CONNECTIONS
* Brown lead A8: Connect to an earthing point on the car body.
¢ Red lead A7: Connect to a switched 12 V supply of the car ignition.
