SECTION 3
INSTALLATION
BE SURE TO READ THE FOLLOWING INSTRUCTIONS BEFORE USE.
3-1 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. It is
recommended you 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.

3-2 RECOMMENDATIONS FOR
INSTALLATION
1. Avoid placing the IC-701 in direct sunlight, high
temperature, dusty or humid places.
2. The left side of the unit, when facing it, functions
also as a heatsink. The temperature there will usually
become relatively warm during transmission. Any
equipment should be at least 1 inch (83cm) away from
the unit so as to provide good ventilation. Be sure that
nothing is on and 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 indication 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!
3-3 POWER SUPPLY
For AC operation, use the special power supply !C-701PS.
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
from 16-20 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
1C-701 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 the 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 on the rear panel of the !C-701. Refer to the
drawing below.

3-4 ANTENNA
Antennas play a very important role in radio communi-
cation. If the antenna is inferior, your transceiver cannot
give you the best performance. With a good antenna and
feeder cable having 50 ohm impedance, you should easily
get the desired matching and performance. Carefully install
a high performance antenna that suits the frequency
band(s) you wish to operate on and place it as high as
possible. Be especially careful of the condition of the
connectors as loose connections will deteriorate the per-
formance. Be sure to connect the ground terminal of a
whip antenna, if used, to the body of your car.
As the output is quite high, avoid connecting the antenna
connector to open lines and do not transmit under
mismatched conditions. Otherwise the final stage could be
overloaded and cause a malfunction of the unit.
