2 INSTALLATION AND CONNECTIONS

■Unpacking

After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping car- tons.

■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 GROUND terminal and ground as short as possible.

For a description and a diagram of accessory equip- ment included with the IC-706MKIIG, see UNPACK- ING on p. ii of this manual.

RWARNING: NEVER connect the [GND] ter- minal to a gas or electric pipe, since the connection could cause an explosion or electric shock.

■Antenna

Select antenna(s), such as a well-matched 50 Ω antenna, and feedline. The transmission line should be a coaxial cable. 1.5 : 1 or better of Voltage Standing Wave Ratio (VSWR) is recommended for your required band. Of course, the transmission line should be a coaxial cable.

CAUTION: Protect your transceiver from lightning using a lightning arrestor.

ANTENNA SWR

Each antenna is tuned for a speciﬁed frequency range and SWR may be increased out-of-range. When the SWR is higher than approx. 2.0 : 1, the transceiver’s power drops to protect the ﬁnal transis- tors. In this case, an optional antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmitting even when using the antenna tuner. The IC-706MKIIG has an SWR meter to monitor the antenna SWR continuously.
