2 SAFETY SUMMARY
2.1 SYMBOLS
This safety requirement symbol (located on the rear panel) has
been adopted by the International Electro-technical Commission,
Document 66 (Central Office) 3, Paragraph 5.3, which directs that
an instrument be so labeled if, for the correct use of the instrument,
it is necessary to refer to the instruction manual. In this case it is
recommended that reference be made to the instruction manual
when connecting the instrument to the proper power source. Verify
that the correct fuse is installed for the power available.
The CAUTION symbol denotes a hazard. It calls attention to an
operational procedure, practice or instruction that, if not followed,
could result in damage to or destruction of part or all of the
instrument and accessories. Do not proceed beyond a CAUTION
symbol until its conditions are fully understood and met.
The NOTE symbol is used to mark information which should be
read. This information may be very useful to the operation when
with the subject covered in this section.
The HINT symbol is used to identify additional comments which are
outside of the normal format of the manual, however can give the
user additional information about the subject.
