Step Action
1. nspect the cardboard carton for obvious damage. f
damaged, call Technical Support at 404-246-8600.
Leave the Mark V Baby Screamer motherboard in its original
packing.
2. Perform all unpacking and installation procedures on a
ground connected anti-static mat. The operator should wear
an anti-static wristband, grounded at the same point as the
anti-static mat. Or use a sheet of conductive aluminum foil
grounded through a 1 megohm resistor instead of the anti-
static mat. Similarly, a strip of conductive aluminum foil
wrapped around the wrist and grounded through a 1 megohm
resistor serves the same purpose as the wrist-band.
3. nside the carton, the motherboard is packed in an anti-static
bag, and sandwiched between sheets of sponge. Remove the
sponge and remove the anti-static bag. Place the
motherboard on a grounded anti-static surface component-
side up. Save the original packing material in case of
reshipment.
4. nspect the motherboard for damage. Press down on all Cs
mounted in sockets to verify proper seating. Do not apply
power to the motherboard if it has been damaged.
5. f the motherboard is undamaged, it is ready to be installed.
