Installation And Connections; Unpacking; Selecting A Location; Grounding - Icom ic-718 Instruction Manual

 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-718, see 'Supplied accesso-
ries' on page 1 of this manual.
 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 electromagnetic sources.
The base of the transceiver has an adjustable stand
for desktop use. Set the stand to one of two angles to
suit your operating conditions.
 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
terminal to a gas or electric pipe, since the connec-
tion could cause an explosion or electric shock.

INSTALLATION AND CONNECTIONS

connect the [GND]
 Connecting an antenna
For radio communications, the antenna is of critical im-
portance, along with output power and receiver sensi-
tivity. Select antenna(s), such as a well-matched 50 Ω
antenna, and feedline. A Voltage Standing Wave Ratio
(VSWR) of 1.5:1 or less is recommended for your desired
band.
NOTE:
A lightening arrestor may offer some pro-
tection from static electricity.
Antenna SWR
Each antenna is tuned for a specifi ed frequency range
and SWR may increase out of that range. When the
SWR is higher than approximately 2.0:1, the trans-
ceiver's power drops to protect the fi nal transistor.
In this case, an antenna tuner is useful to match the
transceiver and antenna. The IC-718 has an SWR
meter to continuously monitor the antenna SWR.
