Installation and Connections
To prevent external noise from entering the audio system.
• Locate the unit and route the leads at least 10 cm away from the car harness.
• Keep the battery power leads as far away from other leads as possible.
• Connect the ground lead securely to a bare metal spot (remove any paint, dirt or grease if necessary) of the car chassis.
• If you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries
various noise suppressors, contact them for further information.
• Your Alpine dealer knows best about noise prevention measures so consult your dealer for further information.
Parking Brake Lead Connection
If necessary, use a pinch connector to connect the parking brake lead, etc.
Connection Diagram of SPST Switch (Sold Separately)
(If the ACC power supply is not available)
NOTE
If your vehicle has no ACC power supply, add an SPST
(Single-Pole, Single-Throw) switch (sold separately). If
the switched power (ignition) lead of the CVA-1003R is
connected directly to the positive (+) post of the vehicle's
battery, the CVA-1003R draws some current (several
hundred milliamperes) even when its switch is placed in
the OFF position and the battery may be discharged.
