Packaging
Your BERG6 receiver is supplied in a hard plastic case
but you have the option of removing it from the hard
case and putting it into the supplied clear shrink tubing.
F.z
The BERG6 receiver comes without a crystal installed.
This receiver was designed to work with our own crystal,
PN RCDXFRxx (replace the xx with channel number).
These crystals are tight tolerance and will only operate
with the BERG6 receiver. The BERG6 receiver will not
operate with other manufacturers crystals.

Advanced ultra narrow-band circuitry design that deals
directly with the types of interference found in our r/c
world lets you fly worry free and makes the BERG6
receiver one of the most stable receiver on the market
today.
Your BERG6 receiver comes installed in a hard plastic
case for its’ protection, but for those of you are looking
for the most in weight savings, it is also provided with a
piece of clear shrink tubing to take the place of the hard
case. You will realize a weight savings of about 8 grams
by removing the plastic case.

If all output ports are used, use a Y Harness in any
channel and plug the servo in one output and the switch
harness into the other output as shown in Example 2.

Thank you for purchasing the BURG6 FM receiver. The
greatest care has been put into the design and
manufacture to provide to you the best in state of the art
performance to be found in a R/C receiver available
today. Its small, lightweight size is due to surface mount
technology used throughout. Attention to detail shows
with features such as selectable modulation shift making
it compatible with all brands of FM transmitters and
th
selectable 5 channel output (channel 5 or 7).

Top label
Remove the case by lifting the top label covering the
FCC label and then lifting the FCC label along the case
seam. You can then remove the receiver through the
bottom of the receiver case.
Hookup
Insert receiver into the clear heat shrink tubing, center it,
and shrink the tubing using a shrink covering heat gun.
Trim around the plugs and you are done.
The BERG6 receiver has 6 output ports. Each of these
is a servo output. Each of these outputs can also be
used for the power input. You can plug your switch
harness into any unused servo port for your power input.

When you purchased your BERG6 receiver you
specified the brand transmitter you were going to use it
with. This is because not all transmitters modulate the
RF in the same polarity. Futaba for example modulates
from negative to positive. JR modulates from positive to
negative. The receiver sees this inverted as an inverted
signal from one another. The receiver logic section is set
up to have either a positive shift signal or a negative shift
signal as it will only work one way. So at the factory it is
set up for one or the other type of signal.
The BERG6 receiver was designed so that either polarity
signal can be used. It does this with the use of an
inverter and three solder pads on the circuit board. The
Positive or Negative
Modulation Shift jumper
the two settings are.
When moving the jumpers, it is not necessary to use the
zero ohm resistor for the bridge. A simple solder bridge
will do. If you do not understand what a solder bridge is,
you would be best off if you found one of your friends
that do know. Let them do the work for you so that you
don’t ruin the receiver trying to do the job yourself.
Wiring for Batteries and Servos
The BERG6 receiver is wired according to industry
standard and is the same as JR, Futaba, and HiTec
brand radios. If you have Airtronics or other brand
equipment, check with the manufacturer first before you
plug a battery into your receiver. Plugging an Airtronics
(non “Z” type) battery into your receiver will blow the unit
out rendering it useless. It also voids your warranty!

polarity of the signal it will operate on depends on the
position of a jumper, or zero ohm resistor across these
solder pads. The drawing above shows the location of

Make sure that any servos that you plug into your
receiver are also wired correctly or are using the proper
adapter cord. Plugging a incorrectly wired servo into any
of the servo outputs will burn out the amplifier of the
servo. It is possible to know of this by the way the servo
does not operate and the terrible smell coming from it!
Again, warranty does not apply!

If you know how to solder, and have an adequate
soldering station, you may change this jumper at a future
date to match a different brand transmitter than the one
you originally purchased the receiver for. Real handy if
you ever sell it to someone else that flies a different
brand than you do!
