Connection
2WARNING
To prevent fire caused by a short in the wiring,
connect a fusible link or breaker nearby the
battery's positive terminal.
2CAUTION
• If sound is not output normally, immediately turn
power off and check connections.
• Be sure to turn the power off before changing the
setting of any switch.
• If the fuse blows, check wires for shorts, then
replace the fuse with one of the same rating.
• Check that no unconnected wires or connectors
are touching the car body. Do not remove
caps from unconnected wires or connectors to
prevent short circuits.
• Connect the speaker wires to appropriate speaker
connectors separately. Sharing the negative wire
of the speaker or grounding speaker wires to the
metal body of the car can cause this unit to fail.
NOTE
• Do not connect cables and leads to both RCA
cable input jacks and the speaker level input
terminals simultaneously, for this may cause
malfunction or damage.
Speaker level input connections
• The genuine-accessory car stereo shall have a
maximum power output of no more than 40 W.
• The power is turned on and off as the unit
detects input signal (Signal Sensing Turn-ON).
There fore it is not necessary to connect the
power control wire.
