Safety Requirement
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.
Use Proper Overvoltage Protection.
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.
Use Proper Fuse.
Please use the specified fuses.

DSG800 User Guide III
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered on.
Do Not Operate With Suspected Failures.
If you suspect that any damage may occur to the instrument, have it inspected by
RIGOL authorized personnel before further operations. Any maintenance,
adjustment or replacement especially to circuits or accessories must be performed by
RIGOL authorized personnel.
Provide Adequate Ventilation.
Inadequate ventilation may cause an increase of temperature in the instrument,
which would cause damage to the instrument. So please keep the instrument well
ventilated and inspect the air outlet and the fan regularly.
Do Not Operate in Wet Conditions.
To avoid short circuit inside the instrument or electric shock, never operate the
instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere.
To avoid personal injuries or damage to the instrument, never operate the
instrument in an explosive atmosphere.
Keep Instrument Surfaces Clean and Dry.
To avoid dust or moisture from affecting the performance of the instrument, keep the
surfaces of the instrument clean and dry.
Prevent Electrostatic Impact.
Operate the instrument in an electrostatic discharge protective environment to avoid
damage induced by static discharges. Always ground both the internal and external
conductors of cables to release static before making connections.
Use the Battery Properly.
Do not expose the battery (if available) to high temperature or fire. Keep it out of the
reach of children. Improper change of a battery (lithium battery) may cause an
explosion. Use the RIGOL specified battery only.
Handle with Caution.
Please handle with care during transportation to avoid damage to keys, knobs,
interfaces, and other parts on the panels.
