Overview

<Removing the Keys>

• To remove the keys, you will need two of the tools described below.

• Before removing a black key, you must fi rst remove both white keys on either side of the black
key.

• White keys may be removed with the same procedures as removing black keys.

<Tool>

• The tool used in the photos in this section was converted from a gardening ID tag. The size
and shape of an ID tag accord to the dimensions below.

<Note on Shaping an ID Tag>

• The thickness of the tool must be within 1.2 ~ 1.3 mm. If the tool is too thin, removing keys
become diffi cult. If the tool is too thick, it may damage the rib of the chassis.
