instruction manual.

• This unit is designed for negative ground 12 V DC operation only.
• Before making connections, turn the car ignition off to avoid short circuits.
• Connect the yellow power input cord only after all other cords have been connected.
• Run all ground leads to a common ground point.

To  a +12 V power terminal which
is energized at all times
Be sure to connect the black ground
lead to it first.

To  a metal point on the car
First connect the black ground lead,
then connect the yellow power input
leads.

•Mount the unit either inside the trunk or under a seat.
•Choose the mounting location carefully so the unit will not interfere with the normal movements of

the driver and it will not be exposed to direct sunlight or hot air from the heater.

•Do not install the unit under the floor carpet, where the heat dissipation from the unit will be

considerably impaired.

First, place the unit where you plan to install it, and mark the positions of the four screw holes on
the mounting surface.

If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after
replacement, there may be an internal malfunction.

Use a fuse with the specified amperage rating.
Use of a higher amperage fuse may cause serious damage.
