12 V DC POWER CONNECTION
The AE 6490 is designed for 12 V (with allowed variations between 10.8 and 15.6 V)
standard car installation (with negative ground) only. Nearly all cars have such a 12 V
car network and even most trucks supply 12 Volts for the electronics equipment in the
cockpit.
The nominal voltage printed on most radios is 13.8 V (which simply means the supply
voltage when the engine is running)
DC cable wiring
• Connect the negative (black) DC power lead to the vehicle chassis or directly
to the vehicle battery negative terminal if preferred.
• Connect the positive (red) DC power lead via the in line fuse to a suitable point
in the vehicle fuse box or directly to the positive battery terminal.
• It is as well possible to connect the radio to a switched 12 V network section to
allow automatic on-off with the ignition switch, because the radio stores all
last used settings
• It may be necessary in some special cases to use a line filter against alternator
noise. This is depending on the position in the car electrical supply system
where you have connected your radio with + and -. If difficulties appear, we
recommend to test other connecting methods in the car installation as well.

• Install DIN Sleeve into the opening in your dashboard, lip facing out.
• Push out the top and bottom tabs to hold the sleeve firmly in place.
• Before inserting this radio in the sleeve, wire the cable from the previously
mounted antenna

on your fuse block, while BLACK connects to the car body ground ( - ).
• Make sure all the connections are routed away from any potentially pinching or
slicing other metallic parts.
