Adjusting the playing height of keys on a WX7

The WX7 originally included two sets of 14 key self-adhesive adjustments shims (0.2mm and 0.5mm), which allow the minute adjustment of each key's playing height to one of three different styles (default, 0.2mm and 0.5mm). To apply the adjustment shims:

1) Remove the plastic covering from the shim, and stick it firmly on the body of the WX7 just under the pad (key cushion) associated with the key to adjust.

NOTE: Shims were originally included with the WX7, however, they are no longer an inventoried item at Yamaha.
