Safety precautions
2WARNING
• Mounting and wiring this product requires skills and
experience. For safety's sake, leave the mounting
and wiring work to professionals.
2CAUTION
• Make sure to ground the unit to a negative 12V DC
power supply.
• Use only the screws provided or specified for
installation. If you use wrong screws, you could
damage the unit.
• If your vehicle's ignition does not have an ACC
position, or if the ignition wire is connected to
a power source with constant voltage such as a
battery wire, the power will not be linked with the
ignition (i.e., it will not turn on and off along with
the ignition). If you want to link the unit's power
with the ignition, connect the ignition wire to a
power source that can be turned on and off with
the ignition key.
• If the fuse blows, first make sure the wires aren't
touching to cause a short circuit, then replace the
old fuse with one with the same rating.
• After the unit is installed, check whether the brake
lamps, blinkers, wipers, etc. on the car are working
properly.
