Connection/Installation
Cautions
• Run all ground (earth) leads to a
common ground (earth) point.
• Do not get the leads trapped under a
screw, or caught in moving parts (e.g., seat
railing).
• Before making connections, turn the car
ignition off to avoid short circuits.
• Connect the power supply lead
unit and speakers before connecting it to
the auxiliary power connector.
• Be sure to insulate any loose unconnected
leads with electrical tape for safety.
Precautions
• Choose the installation location carefully so
that the unit will not interfere with normal
driving operations.
• Avoid installing the unit in areas subject to
dust, dirt, excessive vibration, or high
temperature, such as in direct sunlight or
near heater ducts.
• Use only the supplied mounting hardware
for a safe and secure installation.
Note on the power supply lead (yellow)
When connecting this unit in combination with
other stereo components, the amperage rating of
the car circuit to which the unit is connected must
be higher than the sum of each component's fuse
amperage rating.
Mounting angle adjustment
Adjust the mounting angle to less than 30°.
Making connections
If you have a power antenna (aerial) without
a relay box, connecting this unit with the
supplied power supply lead
may damage
the antenna (aerial).
