WARNING
This manual contains safety information which the user must follow to ensure safe operation of this
instrument. WARNING information is intended to protect the operator; CAUTION information is
intended to protect the instrument. The following general safety precautions must be observed during all
phases of operation, service, and repair of this instrument. Failure to comply with these precautions or
with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and
intended use of the instrument.
Warning statements precede potentially dangerous procedures throughout this manual. The instruc-
tions contained in the warnings must be followed. The following warning statements are found in this
manual:
Use a proper power source. This instrument is intended to be operated from a single-phase power
source. A suitable power source is one where both current-carrying conductors are ungrounded, since
over-current protection (fuse) is provided in both conductors. Operation from a grounded power source
is not recommended. If the fuse in the grounded conductor opens, the power-source voltage appears on
the internal primary wiring causing a possible shock hazard during troubleshooting.
Ground the instrument. This instrument has a three-wire power cord with a three-terminal polarized
plug for connection to the power source and safety-earth. The safety-earth terminal of the plug is directly
connected to the instrument frame. For electric-shock protection, insert this plug only in a mating outlet
with a safety-earth contact or otherwise connect the frame to a safety-earth system. Failure to complete
the ground system may allow the chassis of this instrument to be elevated above ground potential and
pose a shock hazard.
WARNING
Avoid live circuits. Dangerous voltages exist at several points throughout this instrument. When the
instrument is operated with the covers removed, do not touch exposed connections or components.
Some transistors have voltages present on their cases. Disconnect power before cleaning the instrument
or replacing parts.
Avoid contact with chemicals.
Handle silicone grease with care. Avoid getting silicone grease in eyes.
Wash hands thoroughly after use.
WARNING
Use care when handling the crt.
Protective clothing and safety glasses should be worn when handling
a crt. Avoid striking it on any object which might cause it to crack or implode. When storing a crt, place it
in a protective carton or set it facedown in a protected location on a smooth surface with a soft mat under
the faceplate to protect it from scratches.
