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,
