The Berg 5*DSP II Receiver can be programmed via two jumpers to use either channel 5 OR channel 6.  By default (at time of this writing!) the Berg 5*DSP II comes with channel 5 enabled.

Here are some hand-assembled jumpers made from part number ME-71400.  Now jumpers are supplied with each Berg and Hyperion programmable receiver, so you need not assemble them.  Note that the jumpers are just servos connectors, with center pin unused and outer two pins connected.

STEP ONE
On left is a picture showing the setup before programming.  The servo connected to channel one will cycle back and forth several times as programming proceeds.  When the servo stops, programming is complete.

STEP TWO

To program for Channel 6, set as shown at Left. 

Channel #1 – Servo
Channel #2 – Jumper
Channel #4 – Jumper
Battery – 4.8-6.0V battery with switch harness
Install BERG crystal, matching Transmitter frequency

STEP THREE  (programming for channel 6)
1) Turn on transmitter
2) Turn on switch to Berg 5*DSP
3) Wait until Servo stops cycling
4) Turn off  switch to Berg 5*DSP and Transmitter switch
5) Programming is complete, and you may use channels 1-4 and 6

STEP FOUR (programming for channel 5)
To return to using channels 1-5, set as above, but place jumpers like this:
Channel #2 – Jumper
Channel #3 – Jumper
And program as in STEP THREE
