Antenna Mounting And Orientation - Lectrosonics DCR822-A1B1 Instruction Manual

Date & Time
Allows setting of calendar date in Year, Month and Day,
and time in 24 hour clock, with minutes and seconds.
This information is then placed in the meta data header
on any .WAV files recorded onto the microSD card.
Locale
The locale should be chosen based on the region where
the receiver is being used. There are three options avail-
able:
- NA: (default setting) represents the North Ameri-
can locale and prevents operation in the
Astronomical Band (from 608 to 614 MHz). It allows
tuning from 470.100 up to 607.950 MHz.
- EU: represents the European locale, and has un-
restricted operation over the entire band of the de-
vice: 470.100 up to 614.375 MHz.
- AU: represents the Australian locale, and has un-
restricted operation over the entire band of the de-
vice: 470.100 up to 691.175 MHz.
Default
This setting restores the unit to factory settings.
About
Displays general information about the DCR822, in-
cluding band, microcontroller and FPGA versions. The
microcontroller 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 re-
ceiver is mounted in either a vertical or horizontal position
with the whips oriented vertically.

Dual Channel Digital Receiver
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.
