When servicing this chassis, under no circumstances should the origi-
nal
design be modified or altered without permission from the Zenith
Radio
Corporation. All components should be replaced only with types
Identical
to
those
In the original circuit. Special
components
are used
to prevent
shock and fire hazard
.
These critical components are shad-
ed
on
the
schematic and parts list for easy Identification.
FOR
X-RADIATION, FIRE OR SHOCK
HAZARD PREVENTION, CERTAIN SPE-
