Turn the unit face down on a soft surface and measure the

resistance between either solder pad for toroid L3 and ground. It
should be > 500 ohms. If it is less, you must find the cause before
proceeding. If the metal tab 2SC2166 is installed at Q6, the most likely
cause will be that the shoulder washer has slipped out or the metal tab
on the transistor is touching the case instead of the thermal pad.

Install the knob on the encoder shaft.

Find the battery holders and inspect the bottom of one. Note the

ridges and nubs that provide a space for wires under the holder. The
holder has one wire running between two molded ridges that connect
the opposite corner cells together.

In the following steps you will install and wire the battery

holders. First, study the wiring drawing in Figure 25. The two holders
are wired in series. The wires must run against the bottom cover and
under the holders as shown to avoid interfering with other components
when the KX1 case is closed.
