This is a Safety Class 1 instrument (provided with a protective earth
terminal) and has been manufactured and tested according to
international safety standards.
Before operation, you should review the instrument and manual for
safety markings and instructions. You must follow these to ensure safe
operation and to maintain the instrument in safe condition.
Some circuits are powered whenever the instrument is connected to the
AC power source. To disconnect from the line power, disconnect the
power cord either at the rear power inlet or at the AC line power source
(receptacle). One of these must always be accessible. If the instrument
is in a cabinet, it must be disconnected from the line power by the
system's line power switch.
To avoid hazardous electrical shock, do not perform electrical tests when there
are signs of shipping damage to any portion of the outer enclosure (covers,
panels, and so on).
Hazardous laser radiation.
Invisible laser radiation.
