General Safety Summary
Please review the following safety precautions carefully before putting the instrument into operation so as
to avoid any personal injury or damage to the instrument and any product connected to it. To prevent
potential hazards, please follow the instructions specified in this manual to use the instrument properly.
Use Proper Power Cord.
Only the exclusive power cord designed for the instrument and authorized for use within the local country
could be used.
Ground the Instrument.
The instrument is grounded through the Protective Earth lead of the power cord. To avoid electric shock,
connect the earth terminal of the power cord to the Protective Earth terminal before connecting any input
or output terminals.
Connect the Probe Correctly.
If a probe is used, the probe ground lead must be connected to earth ground. Do not connect the ground
lead to high voltage. Improper way of connection could result in dangerous voltages being present on the
connectors, controls or other surfaces of the oscilloscope and probes, which will cause potential hazards for
operators.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings and markers on the instrument and check your manual for
more information about ratings before connecting the instrument.

Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise,
the operator might be exposed to the danger of an electric shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Do Not Insert Objects Into the Air Outlet.
Do not insert objects into the air outlet, as doing so may cause damage to the instrument.
