Your instrument was designed with protective covers to prevent exposure to dangerous voltage
and other electrical hazards. If you see either of the following symbols on your instrument,
there is a risk of electric shock in the vicinity of the symbol.
WARNING Do not block access to the power supply, AC power cord or power switch.
WARNING To avoid injury, only a qualified person using the appropriate measuring
device should check the line voltage, current and frequency.
CAUTION Only our trained and certified service representatives should attempt to service
a component that carries either of these symbols.
CAUTION If a protective cover on a system component appears damaged, turn off the
system and secure it against any unintended operation. Always examine the protective
cover for transport stresses after shipping.
CAUTION Even after this instrument has been disconnected from all voltage sources,
capacitors may remain charged for up to 30 seconds and can cause an electrical shock.
CAUTION To avoid a shock hazard, do not allow liquid to run into the power supply or
the back of the instrument.
CAUTION To avoid a shock hazard, do not attempt to remove the cover of the power
supply.
IMPORTANT Sample compartment windows can be damaged by exposure to liquid. Do
not allow liquids to come into contact with these windows.
Your instrument is protected by fuses that are built into the external power supply. These fuses
are not individually replaceable. If the fuses blow, you must replace the power supply.
