Installation - Icom IC-730 Instruction Manual

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 RECOMMENDATI ONS FOR INSTALLATION
1. Avoid placing the IC-730 in direct sunlight, high temp-
erature, 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 and just
behind the rear PA heatsink to ensure good ventilation.
Also avoid places near outlets of heaters, ai r 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 IC-PS15.
If you would like to use you r 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
maxi mum 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
IC-730 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 IC-730. Refer to the
drawing below.

3 - 4 MEMORY BACK-UP
To retain the memory in the CPU, keeping the operating
frequencies of the V FOs even when the main Power
Switch is turned OFF, connect a power source of 9 to 12
Volts DC to the Memory Back-U p terminal on the rear
panel. For mobile installation this can be accomplished
by direct connection to the car battery since the current
drain is low.
