Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made
by qualified maintenance personnel. Do not replace components with the power cable connected. Under certain conditions
dangerous voltages may exist even though the power cable was removed; therefore, always disconnect power and
discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE.
