1 -1 Safety Precautions
1.
When reinstalling the chassis and its
assemblies, be sure to restore all protective
devices, including: nonmetallic control knobs
and compartment covers.
Make sure there are no cabinet openings
through which people — particularly children —
might insert fingers and contact dangerous
voltages. Such openings include excessively
wide cabinet ventilation slots and improperly
fitted covers and drawers.
Design Alteration Warning:
Never alter or add to the mechanical or
electrical design of the ECR. Unauthorized
alterations might create a safety hazard. Also,
any design changes or additions will void the
manufacturer's warranty.
Components, parts and wiring that appear to
have overheated or that are otherwise
damaged should be replaced with parts that
meet the original specifications. Always
determine the cause of damage or overheating,
and correct any potential hazards.
1-2 Servicing Precautions
the following areas: sharp edges, and
especially the AC and high voltage supplies.
Always inspect for pinched, out-of-place, or
frayed wiring. Do not change the spacing
between components and the printed circuit
board. Check the AC power cord for damage.
Make sure that leads and components do not
touch thermally hot parts.
Product Safety Notice:
Some electrical and mechanical parts have
special safety-related characteristics which
might not be obvious from visual inspection.
These safety features and the protection they
give might be lost if the replacement
component differs from the original - even if
the replacement is rated for higher voltage,
wattage, etc.
Components that are critical for safety are
indicated in the circuit diagram by shading,
(<1) or (A\).Use replacement components that
have the same ratings, especially for flame
resistance and dielectric strength specifications.
A replacement part that does not have the
same safety characteristics as the original might
create shock, fire or other hazards
precautions.
1. Servicing precautions are printed on the
cabinet. Follow them.
2. Always unplug the unit's AC power cord from
the AC power source before attempting to:
(a) Remove or reinstall any component or

assembly, (b) Disconnect an electrical plug or
connector, (c) Connect a test component in
parallel with an electrolytic capacitor.
Some components are raised above the printed
circuit board for safety. An insulation tube or
