E Unpacking
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
E 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.
E Antenna
For radio communications, the antenna is of critical im-
portance, along with output power and sensitivity.
Select good antennas and mounting locations. The
transceiver accepts a 50 Q antenna and less than 3:1
of Voltage Standing Wave Ratio (VSWR).
E Antenna connectors
For a description and a diagram of accessory equip-
ment included with the IC-821H, see UNPACKING on
p. ii of this manual.
OPERATING ANGLE ADJUSTMENT
The stand on the bottom of the
transceiver provides two operating angles.
The transceiver requires 2 antennas for 144 and 430
MHz operation. Of course, the transmission line should
be a coaxial cable.
CAUTION: Protect your transceiver from lightning
using a lightning arrestor.
