Heeding maintenance considerations

Safety and handling

Observe these warning and caution advisories when performing instrument
maintenance.
Warning:
solvents, changing tubing, or operating the instrument. Know the
physical and chemical properties of the solvents you use, and consult
their Material Safety Data Sheets.
Caution:
• To avoid damaging electrical parts, never disconnect an electrical
assembly while power is applied to the instrument. To completely
interrupt power to the instrument, set the power switch to Off,
and then unplug the power cord from the AC outlet. After power is
interrupted, wait 10 seconds before disconnecting an assembly.
• To prevent circuit damage due to static charges, touch no
integrated circuit chips or other system instruments that require
no manual adjustment.
Warning:
panels to complete any instrument maintenance procedures. Doing so
exposes potentially dangerous voltages.
