The multifunction security device is provided with an easy and durable
method for reminding the user of content programmed in each programmable
key. First preprint (or write) in each cell of the attached colored legend sheet the
“name” for each key. Stick each cell to the corresponding keytop and then put
on the transparent key cap from the accessories. In this way, the labeling will be
protected and resistant to scratch or rubbing.
When re-labeling is required, please use the attached key clip to hook up
the transparent key cap and change the label then re-cap.

handy programming tool in the software so that the system command keys will
not be wiped out. So the description on the programming utility supported by the
