UNPACKING
Carefully remove your transceiver from the packing carton
and examine
it for signs of shipping damage.
Should any
be apparent,
notify the delivering
carrier or dealer im-
mediately,
stating the full extent of the damage.
|t is
recommended
you
to keep the shipping cartons.
In the
event storage, moving, or reshipment
becomes
necessary
they
will
be handy.
Accessory
cables, plugs, etc., are
packed
with
the
transceiver.
Make
sure you
have
not
overlooked anything.

RECOMMENDATIONS
FOR
INSTALLATION
1. Avoid
placing
the
IC-471H
in direct
sunlight,
high
temperature, dusty or humid places.
2. The temperature of the set will usually become relatively
warm
during transmission.
Any equipment should be at
least 1 inch (3cm) away from the unit so as to provide
good ventilation.
Be sure that nothing
is on or just
behind the rear PA heatsink to ensure good ventilation.
Also avoid places near outlets of heaters, air conditioners,
etc.
3. Place the unit so that the controls and switches
can
easily be handled and the frequency display and meter
can easily be read.
4. For mobile
installation, an optional mounting bracket
is available.
Select the best location that can stand the
weight of the unit and that does not interfere with your
driving in any way.
5. Use the Ground Lug!

POWER
SUPPLY
For AC operation, use the special power supply IC-PS15,
|С-Р530, or optional built-in power supply IC-PS35.
If you
would like to use your car battery or any other DC power
supply, be sure that its output voltage is 12-15 Volts and
the current capacity is at least 20 Amps.
The maximum
power
consumption
of the set during transmission
runs
about 20 Amps, so keep that in mind if the unit is installed
in your automobile, and turn it on after you have started
the engine.
Attention should also be paid to the condition
of the battery and electrical system.
The connection of the DC power cord supplied with the
1С-471Н
is done
in the following way:
First make sure
that the power switch of the unit is in the OFF position
and the T/R switch is in the receive position.
Connect the
cord to
a DC power
supply with the RED
lead to the
positive
terminal
and
the
BLACK
lead
to the negative
terminal.
(Reverse connection
will cause the protection
circuit to operate and blow the fuse.)
Connect the DC plug
to the socket оп the rear panel of the IC-471H.
Refer to
the drawing below.

ANTENNA
The
single
most
important
item
that will
influence
the
performance of any communication system is the antenna.
For that reason, a good, high-quality, gain antenna of 50
ohms impedance is recommended, for fixed or mobile.
in
UHF as well as the low bands, every watt of ERP makes
some
difference.
Therefore, 75 watts average output plus
3dB of gain antenna equals 150 watts ERP, presuming low
VSWR
of course.
The few extra dollars invested in a gain
type antenna is well worth it. When adjusting your anten-
na,
whether
mobile
or
fixed,
by all means
follow
the
manufacturer's instructions.
There
are
however
some
pitfalls to
be aware
of.
For
example, do not attempt to adjust an antenna for lowest
VSWR when using a diode VSWR meter not engineered for
UHF
applications.
Such readings will invariably have an
