IGNITION
• If your vehicle has no ACC power supply, add an SPST (Single-Pole, Single-Throw) switch (sold separately) and fuse (sold separately).
• The diagram and the fuse amperage shown above are in the case when IVA-D300 is used individually.
• If the switched power (ignition) lead of the IVA-D300 is connected directly to the positive (+) post of the vehicle‘s battery, the IVA-D300 draws
some current (several hundred milliamperes) even when its switch is placed in the OFF position and the battery may be discharged.
Parking Brake Lead Connection
If necessary, use a pinch connector to connect the foot brake lead, parking brake lead, etc.

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.
