 For the purposes of this manual, “left” and “right” references will refer to the MiTail’s orientation when worn on the body, relative to the wearer. So, the “left” side is the side of the MiTail on the wearer’s left.

+===== Installing Cable Pullies / Servo Horns =====
+There are seven screws holding the pully assembly halves together. Three are at the edge, near the cable slot. And four more that hold the servo horn to the pully. All seven must be removed or loosened to free the cable from the pulley (which is required if the case is being replaced). The screws are M3 × 5.75 mm, Pozidriv PZ1 drive, 7.75 mm overall length.
+<WRAP round important 90%>
+Note that the pulley screws are soft metal. Using a medium-sized electric screwdriver that's slow and steady with very firm downward pressure so the bit doesn't skip and grind out the heads. Do not install or remove the screws with the pulley attached to the servo to avoid damaging the servo shaft and/or gearbox.

+==== Pully Calibration / Resetting Servo Home Position ====
- To do this correctly, first power up the PCB with the new servo attached directly to the board. That will center or "home" the servo before you reattach the pulley. Secondly, make sure the pulley is in the following "ten minutes to the hour" position; the topmost screw head will also align with the servo mount rib below it (note that the servo splines may not line up perfectly and may land a tooth to the left or the right slightly or a particular trail might bias more towards the center screw):

 ===== Charging =====
-MiTail requires a USB Power Delivery (USB PD) capable charging adapter. PD charging is only possible using a USB-C to USB-C cable and a USB PD chargers together. Adapters with USB-A output, even with a USB-A to USB-C cable will **NOT** charge a MiTail. The adapter should provide at least 9V - almost all PD adapters can. If the adapter's rated power is less than 24W, charging will take around 3 hours.
