Safety Requirement
General Safety Summary
Please review the following safety pre cautio ns ca refully 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 specif ied in this manual to use the instrument properly.
Use the BNC Output Connector Properly.
The BNC output connector on the front panel only allows to output the signal but not
to input the signal.
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 th rou gh t he Protective Earth lead of the p ower cord. To
avoid e lectr ic 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 hi gh volta ge. Imp roper w ay of connection could resul t in
dangerous vo l t ages 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 ratin gs and ma rkers on the instrume nt and
check your manual for more information about ratings before connecting the
instrument.
Use Proper Overvoltage Protection.
Ensure that no over voltage (su ch as that cause d by a bolt of lightni ng) 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.
II DG900 User's Guide
RIGOL
Use Proper Fuse.
Please use the specified fuses.
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 maintenan ce,
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 Product Surfaces Clean and Dry.
T o a void dust or moisture from af fecting the pe rformance of the inst rument, keep th e
surfaces of the instrument clean and dry.
Prevent Ele c tr o static Impa ct.
Operate the instrume nt i n an el ectr ostatic dischar ge protect ive envi ron ment to a vo id
damage induced by static discharges. Always ground both the internal and external
conductors of cables to release st a t i c before making connections.
Use the Battery Properly.
Do not expose the bat tery (if av ailable) t o 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.

Care and Cleaning
Care
Do not store or le ave the instrument where it may be exposed to direct sunlight for
long periods of time.
Cleaning
Clean the instrument regularly according to its operating conditions.
1. Disconnect the instrument from all power sources.
2. Clean the external surfaces of the instrument with a soft cloth dampened with
mild detergent or water . Avoid havin g any water or o ther objects into the chassis
via the heat dissipation hole. When cleaning the LCD, take care to avoid
scarifying it.
To avoid damage to the instrument, do not expose it to caustic liquids.
To avoid short-circuit resulting from moistu re or personal injuries, ensure
that the instrument is completely dry before connecting it to the power

To Prepare for Use
To Connect to AC Power
Please use the power cord provided in the accessories to connect the signal
generator t o th e AC power source , as shown i n th e figure below . T he r ated AC pow er
source supported by the signal generator is (100-127 V, 45-440Hz) or (100-240 V,
45-65Hz), and its maximum input power shall not exceed 30 W. When the signal
generator is connected to the AC power source via the power cord, the instrument
automatically adjusts itself to within the proper voltage range, and you do not need
to select the voltage range manually.
To avoid electric shock, ensure that the instrument is correctly
