Safety Symbols
Some adjustments described in the manual, are made with power supplied to
the instrument, and protective covers removed. Energy available at many
points may, if contacted, result in personal injury.
Any adjustment, maintenance, and repair of the opened instrument under
voltage should be avoided whenever possible. When inevitable, this has to be
carried out by a skilled person who is aware of the hazard involved. Do not
attempt internal service or adjustment unless another person, capable of
rendering first aid and resuscitation, is present. Do not replace components
with power cable connected.
Do not operate the instrument in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.
Do not install substitute parts or make any unauthorized modification to the
instrument.
Capacitors inside the instrument may still be charged, even though the
instrument has been disconnected from its source of supply. Dangerous
voltages, capable of causing serious personal injury, are present in this
instrument. Use extreme caution when handling, testing and adjusting.
When working with solvents please observe appropriate safety procedures
(e.g. goggles, safety gloves and protective clothing) as described in the material
handling and safety data sheet by the solvent vendor, especially when toxic or
hazardous solvents are used.
