C.KEYTOP LAYOUT

The basic layout of this programmable keyboard is a matrix with 6 rows and 15 columns to provide maximum 84 positions for push keys with a 6 position control key and LED indicators. Within these 84 positions there is four by four matrix below the control key area configured as numerical keypad. This numerical keypad is a set of “numerical keys” which is composed of 12 numerical keys each is preprinted with one from the set of “0”, “00”, “.”, “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8” and “9” plus “-”, “+” and a double size “Enter” key (ref. Fig. 3-7). However, there are means for the user to break the monotony and to improve the efficiency in application of this programmable keyboard.

First of all, there are 4 legend sheets of different colors in the accessory bag that the user may want to print the identification for each programmed key into each cell of the sticker matrix and then stick each cell printed with the identification onto the surface of the corresponding key top. A key cap from the accessory bag can be snapped on the key top to protect the sticker (ref. Fig. 3-3). In this way the user may feel a lot easier in using the programmable keyboard.

At the bottom of the programmable keyboard, the user may find an adjustable key clip which can be used to pick up the key cap whenever required (ref. Fig. 3-3). The two “feet” of the key clip should be pulled wide for use with double key (ref. Fig. 3-4). It is advisable to use a flattop (minus sign) screw driver to help getting the key top off when necessary (ref. Fig. 3-3 and 3-4 ).
