Connection example
This unit is designed for negative ground 12 V DC operation only.
Before making connections, disconnect the ground terminal of the car battery to avoid short circuits.
Connect the yellow and red power input leads only after all other leads have been connected.
Be sure to connect the red power input lead to the positive 12 V power terminal which is energized
when the ignition key is in the accessory position.
Run all ground wires to a common ground point.
Connect the yellow cord to a free car circuit rated higher than the unit’s fuse rating. If you connect
this unit in series with other stereo components, the car circuit they are connected to must be rated
higher than the sum of the individual component’s fuse rating. If there are no car circuits rated as
high as the unit’s fuse rating, connect the unit directly to the battery. If no car circuits are available
for connecting this unit, connect the unit to a car circuit rated higher than the unit’s fuse rating in
such a way that if the unit blows its fuse, no other circuits will be cut off.
The use of optical instruments with this product will increase eye hazard.
Change the position with a jeweler’s screwdriver, etc.

Notes on speaker connection
• Before connecting the speakers, turn the unit off.
• Use speakers with an impedance of 4 to 8 ohms, and with adequate power handling capacities. Otherwise, the speakers
may be damaged.
• Do not connect the terminals of the speaker system to the car chassis, and do not connect the terminals of the right
speaker with those of the left speaker.
• Do not attempt to connect the speakers in parallel.
• Do not connect any active speakers (with built-in amplifiers) to the speaker terminals of the unit. Doing so may damage
the active speakers. Therefore, be sure to connect passive speakers to these terminals.
