38	1.<br>
39	</strong>If you going to solder to the motor tabs, it's a good idea to
40	bend them out of the way before installing the encoder. If you're going to
41	use push on connectors this step isn't necessary. Be sure to orient the
42	motor as shown EXACTLY as the raised plastic (name, logo and plus sign)
43	will prevent the adhesive from making good contact if the encoder is not
44	applied with the proper orientation.</font></td>

54	2.</strong><br>
55	Before removing the adhesive backing material, fit the sensor to the motor
56	as shown. It has to be oriented EXACTLY as shown for proper fit. When you
57	are happy with the placement, remove the backing and carefully press it in
58	place. I have not needed the expensive alignment tool from US Digital to
59	do this, but you have to be careful not to press it firmly until it is
60	exactly centered. If you are good with your hands this will be easy. If
61	you have ten thumbs, you might want to ask for help.</font></td>
