Freedom 9s polarity

My new Freedom 9s doesn't have any markings for pin polarity. Sticker shows channels 1 thru 9, but not the polarity. Gotta know how to plug the battery and servo's in. Does anybody know what they are?
Thanks

Typical of all hard cased receivers, cases are not marked but slots are shaped to match plugs which fit easily one way only. Match bevelled edge of S-01 Hitec and other servos (or the keyway on Futaba "J" plugs) to the shaped pinout slots as per attached picture of HSD_09RQ - Freedom 9S.
Refer also attached manuals, the Korean version is fully illustrated.
Earlier post Hitec - Synthesised HSD-09RQ (Freedom 9S) Manual and set-up has further detail.
"Remote push button. Allows user to programme RX without removal from a model. Especially usefull when receiver is installed in some difficult to access place in the depths of a model."

Removed one link and attached "Pin Polarity" .pdf with text and photos relating to all other Hitec Soft and Hard cased RX.
This as the photos had expired on that forum.
