DSR4
- AU: represents the Australian locale, and has un-
restricted operation over the entire band of the de-
vice: 520.000 to 614.375 MHz for A1B1. For B1C1,
the range is 537.600 to 691.175 MHz.

Default

This setting restores the unit to factory settings.

About

Displays general information about the DSR4 , including
band, microcontroller and FPGA versions. The microcon-
troller version number is the first number under the band,
followed by the FPGA version number after the forward
slash.

Antenna Mounting and
Orientation
A variety of accessories are available to enable vari-
ous antenna mounting options. For maximum operating
range, the antennas should be vertical and above the
camera and other equipment. The AMJ Rev. A antenna is
jointed so the whips can be oriented vertically regardless
of the orientation of the receiver.
Maximum sensitivity is perpendicular to the whip, so
an ideal setup is shown in Fig. 1 and Fig. 2 where the
receiver is mounted in either a vertical or horizontal posi-
tion with the whips oriented vertically.
Fig. 3 depicts the receiver and antenna whips oriented
horizontally, which places the null of the receiver antenna
pattern pointing toward the transmitter. The result, of
course, is a weak signal entering the receiver.
Fig. 4 depicts the worst setup where the nulls in both
receiver and transmitter patterns face one another.
The transmitter antenna whips can point upward as
shown in these diagrams, but they will work just as well
with the whip pointing downward. Mount the transmit-
ter so that the whip is vertical and not in direct contact
with the wearer's body or metallic objects in clothing and
costuming.
