INSTALLATION
Antenna Considerations
The FT-712RH is designed for use with an antenna having an impedance near 50
ohms at the operating frequency. For optimum performance use a high-quality,
carefully designed antenna. The antenna should be connected at all times when
power is on, to avoid damage that can otherwise result if transmission occurs
accidentally when no antenna is connected.
Another important consideration is the feedline. For optimum performance use
the shortest possible length of the best quality coaxial cable available, and be
sure to use a properly matching plug (type-N) for the jack on the transceiver.
Mobile Installation
The FT-712RH must only be installed in cars having a negative ground electrical
system. The transceiver should be located where the display, controls and
microphone are easily accessible, and should be securely affixed using the
supplied MMB-37 mobile mounting bracket. The transceiver may be installed in
any position without adversely affecting its performance, but it should not be
mounted near a heater vent or where it could interfere with safe operation of the
vehicle. Make sure that plenty of space is provided at the rear of the transceiver
so that air can flow freely around the heatsink. Refer to the diagrams on the
facing page for installation of the MMB-37.
(1)
Using the mounting bracket as a template, locate the mounting holes after
determining the mounting location with sufficient clearance for the
transceiver. Use a 4.8mm (3/16") bit to drill the holes. Secure the bracket
with the supplied screws, washers and nuts (Figure 1).
(2)
Screw the two mounting clips to the sides of the transceiver using the small
hex bolts and washers supplied (Figure 2).
