Thisequipmentgenerates, uses and can radiateradio frequency
energy.
If the equipmentis not installed and used in strict
accordance with the instruction manual,
it may cause
interference to radio communications.
Thisequipmenthasbeentested
and found tocomply with limits
fora Class Adigitaldevice,
pursuant to Part 15 of the FCC Rules.
These limits aredesigned to provide reasonable protection
against harmful interference
when equipment is operated in a
commercial environment.
When thisequipmentisoperated ina residentialarea,itislikely
to cause interference. In this case, the interference
must be
corrected at the operator'sexpense.
Do not connect external equipment to the utility outlets
in
CONVEX equipment cabinets. Unauthorized connection voids
all agencies' emissions certification.
The Elite 3
and related assemblies are sensitive to static
electricity. Although some devices such as metal-oxide
semiconductors areextremely sensitive, all semiconductors, as
well as some resistors
and capacitors, may be damaged or
degraded by exposure to static electricity.
Electrostatic damageto electronic devices
may becaused by the
direct discharge of a charged conductor or by exposure to the
static fields surrounding charged objects.
To avoid electrostaHc damage, service personnel must observe
the following precautions when servicing equipment:
Preface xiii

xiv Elite 3 Disc Drive Service Guide
• Ground yourself to the peripheral cabinet or a grounded
service area whenever working on the Elite 3 or related
assemblies, or whenever electronics will
be exposed.
Connect yourself to ground with a wrist strap. Connection
maybe made to any grounded metal assembly
in the
peripheral cabinet. Remember that you
and the electronic
devices must bothbe grounded to avoid potentially
damaging static discharges.
• Tumoff power before removing or installing power cords.
• Shut downConvexOS before cabling drives to the IDC
bulkhead.
• Do not remove any circuit boards from the drive.
• Never use an ohmmeter on any Elite 3 c.ircuit board.
