Connection

The cable supplied uses high quality lightweight flexible wires.  The flat connector is intended for permanent installation purposes only.  It is not intended as a connector that is regularly disconnected and reconnected.  The connector will only fit with the correct orientation as shown.  If you need to disconnect the Shift-P2, switch the power off and push the locking tabs shown to release.  Recommended method is to use a small flat blade screwdriver to release one tab at a time.

Micro-USB socket is also included for future firmware updates that may be made available.
