INSTALLATION AND CONNECTIONS
n
Unpacking
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
For a description and a diagram of accessory equip-
ment included with the IC-910H, see ‘Supplied acces-
sories’ on p. 1 of this manual.
n
Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the transceiver through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance
between the [GND] terminal and ground as short as
possible.
R
WARNING: NEVER
connect the [GND]
terminal to a gas or electric pipe, since the connec-
tion could cause an explosion or electric shock.
n
Selecting a location
Select a location for the transceiver that allows ade-
quate air circulation, free from extreme heat, cold, or
vibrations, and away from TV sets, TV antenna ele-
ments, radios and other electro-magnetic sources.
The base of the trans-
ceiver has an adjust-
able stand for desktop
use. Set the stand to
depending on your op-
erating conditions.
n
Antenna connection
For radio communications, the antenna is of critical im-
portance, along with output power and sensitivity. Se-
lect antenna(s), such as a well-matched 50
Ω
anten-
na, and feedline. 1.5:1 or better of Voltage Standing
Wave Ratio (VSWR) is recommended for your desired
band. Of course, the transmission line should be a co-
axial cable.
CAUTION:
Protect your transceiver from lightning
by using a lightning arrestor.

Slide the nut, rubber
gasket and clamp over the
coaxial cable, then cut the
end of the cable evenly.
Strip the cable and fold the
braid back over the clamp.
Soft solder the center con-
ductor. Install the center
conductor pin and solder it.
Carefully slide the plug
body into place aligning the
