Installation
Do not lift this transceiver by holding the Tuning control
or other control knobs on the front panel or the
connectors on the rear panel. Doing so may result in
injury or damage of the control knobs.
Antenna Installation and Connection
The antenna system is made up of the antenna, coaxial cables and
a ground terminal. Installing the antenna system carefully and
properly helps to optimize the performance of the transceiver.
Make use of a correctly-adjusted 50 antenna, 50 coaxial
cables and appropriate connectors. Make sure that all
connections are cleaned and free of dirt before fastening them.
Match the impedance of the coaxial cable and antenna such
that SWR is 1:1.5 or lower.
A high SWR may lower the TX output power, thereby causing
radio interference with electrical appliances such as radio and
TV as well as failure of this transceiver.
If reports on signal distortion are received, this means the
transceiver may not be transmitting efficiently.
Transmitting without connecting the antenna may
damage this transceiver. Before transmission, connect
an antenna or a 50 dummy load to this transceiver.
The protection circuit of this transceiver will be activated
if the SWR of the antenna exceeds 1.5. Use an antenna
with a low SWR.
When an RX antenna that makes use of semiconductors
(such as an active antenna) is connected, transmission
or antenna tuning must not be performed. Doing so
supplies power to the antenna and may damage the
semiconductor circuit of the antenna.
Ground Connection
Connect to the ground terminal correctly to avoid risks such as
electric shock.
First of all, bury one or multiple ground bars or a large copper sheet
in the ground and connect them to the GND terminal of this
transceiver. Use a thick conducting wire or a cut copper band that
is as short as possible for this connection.
Gas pipes, conduit pipes for power distribution, plastic
water pipes and the like must not be used for grounding.
Not only are they ineffective for grounding, they may also
result in accidents or fire.
Installation of Lightning Arrestors
To prevent fire, electric shock, malfunctioning and injury due to
lightning, install a coaxial lightning arrestor.
Besides installing a coaxial lightning arrestor, disconnect the
cable of the antenna from this transceiver if lightning is
anticipated.
Connection of Regulated DC Power Supply
Make sure to turn off the power of the regulated DC
power supply before connecting the DC power cord.
Do not insert the power plug of the regulated DC power
supply into the AC outlet until all the connections are
complete.
A DC 13.8 V regulated DC power supply is needed for using this
transceiver. It cannot be connected directly to an AC outlet. Use
the supplied DC power cord to connect this transceiver to the
regulated DC power supply.
The current capacity needed for the regulated DC power supply
is 22.5 A and above. Use one with sufficient current capacity.
1 Connect the DC power cord to the regulated DC
power supply.
Connect the red wire to the “+” terminal and the black wire to
the “-” terminal.
2 Next, connect the DC power cord to the DC 13.8 V
power connector of this transceiver.
Insert the cord fully into the power connector.
Using the Auxiliary Support
An auxiliary support is stored inside the front leg of this transceiver.
Pull it toward you if you want the panel to face slightly upwards.
