INSTALLATION AND CONNECTIONS

I 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.

I 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 be-
tween the [GND] terminal and ground as short as pos-
sible.
R WARNING: NEVER
terminal to a gas or electric pipe, since the connec-
tion could cause an explosion or electric shock.

I 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.

I 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 antenna,
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 coaxial
cable.
CAUTION:
by using a lightning arrestor.
