1-1 Safety Precautions

1) Before returning an instrument to the customer, always
make a safety check of the entire instrument, including, but
not limited to, the following items:

(1) Be sure that no built-in protective devices are defective
     or have been defeated during servicing.
     (1) Protective shields are provided to protect both the
     technician and the customer. Correctly replace all
     missing protective shields, including any remove for
     servicing convenience.
     (2) When reinstalling the chassis and/or other
     assembly in the cabinet, be sure to put back in place
     all protective devices, including, but not limited to,
                                                                                        AC Leakage Test
