installing it in 3 recreational vehicle, *:
ar bus, check the battery voltage.
Jo avoid shorts in the electrical system, be
sure to disconnect the © battery cable
before beginning installation.
Check whether installation and wiring have
been completed correctly. Replace the
removed car components, then connect the
end of the cable to the negative © terminal
of the battery.
Refer to the owner's manual for details on
connecting the power amp, then make con-
nections correctly.
Secure the wiring with cable clarnps or
adhesive tape. To protect the wiring, wrap
it in adhesive where it lies against metal
parts.
Route and secure all wiring so it cannot
touch any moving parts, such as the gear
shift, handbrake and seat rails. Do not
route wiring in places that get hot, such as
near the heater outlet. If the insulation of
the wiring melts or gets torn, there is a
danger of the wiring short-circuiting to the
vehicle body.
Don't pass the orange lead through a hole
into the engine compartment te connect to
the battery. This will damage the lead insu-
lation and cause a very dangerous short.
Do not shorten any leads. If you do, the
protection circuit may fail to work when it
should.
Never feed power to other equipment by
cutting the insulation of the power supply
lead of the unit and tapping into the lead.
The current capacity of the lead wil! be
exceeded, causing overheating.

Since a unique 5 circuit is employed,
never wire so the speaker igads are directly
grounded or the lef and right > speaker
jeads are common.
Speaker corinected to tis unit qiast be
high-power types possessing minimum
rating of 35 W and impedance of 4 to &
ohms. Connecting speakers with output
and/or impedance values other than those
noted here can damage the speakers.
When a power amp is being linked witt
this system, be sure not to connect the blue
lead to the amp's power terminal. Likewise,
when linking this system with the auto-
antenna, do not connect the biue lead to
the antenna's power terminal. Such con-
nections can make overcurrent and cause
malfunctions.
When the unit is mounted in a vehicle
whose ignition switch does not have the
ACC (accessory) position as shown below,
be sure to connect the red lead of the unit
to the terminal! controlled by the ignition
switch ON/OFF position. If you do not, the
vehicle battery may go flat when you leave
your vehicle for several hours
