If youconnect the ignition wire to a power source with aconstant voltage supply, such as with battery wires,the battery may be drained.• If the fuse blows, first make sure the wires are nottouching to cause a short circuit, then replace the oldfuse with one with the same rating.• Insulate unconnected wires with vinyl tape or othersimilar material. To prevent a short circuit, do notremove the caps and do not let the cable out at theends of the unconnected wires or the terminals.• Secure the wires with cable clamps and wrap vinyltape around the wires that comes into contact withmetal parts to protect the wires and to prevent shortcircuit.• Connect the speaker wires correctly to the terminalsto which they correspond. The unit may be damagedor fail to work if you share the · wires or groundthem to any metal part in the car.• When only two speakers are being connected to thesystem, connect both connectors either to the frontoutput terminals or to the rear output terminals (donot mix front and rear).

Otherwise scratches,damage, or failure may result.• If the power is not turned on (“Miswiring DC OffsetError”, “Warning DC Offset Error” is displayed),the speaker wire may have a short circuit or havetouched the chassis of the car and the protectionfunction may have been activated. In this case, thespeaker wire should be checked.WARNINGS• DO NOT connect the ignition wire (red) and thebattery wire (yellow) to the car chassis (ground), youmay cause a short circuit, that in turn may start a fire.• DO NOT cut out the fuse from the ignition wire (red)and the battery wire (yellow).
