12 V / 24 V DC POWER CONNECTION
The AE 6491 CT version can operate at both 12 or 24 V voltage systems. A switching is
not necessary.
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 DC 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.
Mounting using DIN Sleeve
If you are not sure how to install your CB Radio in your vehicle using the DIN sleeve,
consult your automobile manufacturer, dealer, or a qualified installer.
Before installing, confirm that this radio fits in the desired mounting area and you have
all the necessary kits to complete the installation.
• Remove the bracket if previously installed.

mounted antenna
• Connect the DC power leads. The RED wire goes to a positive( + ) connection
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.
• Slowly slide the radio into the sleeve until it locks in place.
• The rubber ring will act as a seal against DIN Sleeve. At the left and right sides
of the ring a slot space will be provided by pulling slowly the left and right side of
the ring.
• The slots in the fitted rubber ring will enable the proper removal of radio from the
DIN sleeve.
