This product is designed to allow the user to reconfigure some hardware options in the field
by changing the plug-in modules in slots 1, 2, 3, & A located on the power supply and 1
st
universal input boards. The main boards (display/CPU, power supply, inputs 1 & 2 and digital
input/USB) are factory fitted, but may be removed while reconfiguring the plug-in modules.
Take care when re-fitting these boards. Observe the power supply board transformer colour,
and case labelling to check the supply voltage, otherwise irreparable damage may occur.
CAUTION: Replacement of boards must be carried out by a technically
competent technician. If the Power Supply board does not match the
labelling, users may apply incorrect voltage resulting in irreparable
damage.
