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 t he instrument and any product connecte d to it. To prevent potential hazards, please us e the instrument only specified by this manual.
Use Proper Power Cord.
Only the 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, it is e ssential t o connect the ea rth terminal of the power cord to the Protective Earth terminal before connecting any inputs or outputs.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has isobaric electric potential as the ground.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings an d markers on the instrume nt and check your manual for more information about ratings before connecting the instrument.
Use Proper Overvoltage Protection.
Make sure that no overvoltage (such as that caused by a t hunderstorm) can reach the product, or else the operator might be exposed to the danger of electrical shock .
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Do Not Insert Anything Into the Holes of Fan.
Do not insert anything into the holes of the fan to avoid damaging the instrument.
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.
II DSG800 User's Guide
RIGOL
Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by RIGOL authorized personnel before further oper at io ns. Any maintenance, adjustment or replacement especially to circuits or accessories must be performed by RIGOL authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause an increase of instrument temperature which would cause damage to the instrument. So please keep the instrument well ventilated and inspect the intake and fan regularly.
Do Not Operate in Wet Conditions.
In order to av oid short circuiting t o the interi or of the device or electric shock, please do not operate the instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damage to the device or personal injuries, it is i mportant to o perate the device away from an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in the air, please keep the surface of the device clean and dry.
Electrostatic Prevention.
Operate the instrument in an electrostat ic discharge protective environ ment to a void damage induced by static discharges. Always ground both the internal and external conductors of cables to release static before making connections.
Proper Use of Battery.
If a battery is supplied, it must not be exposed to high temperature or in contact with fire. Keep it out of the reach of children. Improper change of battery (note: lithium battery) may cause explosion. Use RIGOL specified batte ry only.
Handling Safety.
Please handle with care during transportation to avoid dam age to keys, knob interfaces and other parts on the panels.
