1.9.2 INSTALLING SD CARDS
 Always turn the machine off and disconnect the machine power cord before you
install a controller option.
 To prevent damage to the controller box, always do your work carefully. Do not put
your hand or a tool into the box when you remove the controller box or install an
option.
 To prevent damage to the circuits on the boards, always touch a metal surface to
remove static charge from your hands before you touch electronic components.
SD cards are held in position by a small spring-lock mechanism.
1. To install an SD card, push it into the slot until it stops, then release it.
