Programming the Pixie-7P
Important Note
: When answering a question, you will need to move the transmitter stick to the yes (full “On” throttle) position or the no (full “Off” throttle) position and keep it there for about 5 seconds. When the
Pixie-7P has accepted your answer, it will flash the LED rapidly. After the LED starts it’s rapid flashing, move the throttle stick to the middle position to confirm that you are ready for the Pixie-7P to ask the next
question.
If you wish to re-program only the cut-off voltage you do not need to continue through the programming steps for the remaining two settings. Once you have programmed the cutoff voltage and the Pixie-7P has
confirmed the selection, instead of returning to mid-throttle for the next question, disconnect battery power, re-connect power, and arm the speed control as normal (see Section 3.0).
*Factory default settings are indicated by an asterisk in the option listings below.
