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

 Be aware that, although the JST-PH 2.0 connectors used on the batteries and across industry are polarized, the polarity that any one battery is set up for is EXTREMELY RANDOM. Positive and negative should be correctly indicated by red and black wires, but the position of the wires in the connector may not be correct for the MiTail (or whatever device you plan on using the battery in), because there's actually no real standard. Plugging in the battery with the polarity reversed can, depending on a lot of factors, be quite bad for the device and/or battery. Be aware that, although the JST-PH 2.0 connectors used on the batteries and across industry are polarized, the polarity that any one battery is set up for is EXTREMELY RANDOM.

 The servos need to be attached in their 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 servo. The ear "home" position is the ears are parallel with the band. Ear position may be offset if desired, keeping in mind that the "home" position is the middle of the ear's range of motion. The servos need to be attached in their home position.
