Power cable
Connect the power cable (supplied) to the power source; white wire to positive
[+] terminal and black wire to negative [-] terminal.
Ground wire
Ground the equipment to prevent noise and interference and enable reception of
weak signals. Run the ground wire (local supply) between the ground terminal
on the facsimile receiver and the ship's grounding bus.
Preamp unit
Connect its coaxial cable directly to the antenna connector on the FAX-30. Note
that an extension cable kit (option) is available, in lengths of 10, 20, 30, 40 and
50 m.
Wire or whip antenna
A junction box or antenna switch (local supply) is required since the connection
at the FAX-30 is made with a coaxial cable. Connect a feeder wire between the
antenna and the junction box or antenna switch. Attach coaxial connector
(option) to a 50 ohm coaxial cable as below and connect the cable between the
junction box and the FAX-30. If the connector does not fit the cable, use
appropriate adaptor (option).
