Read All Warnings and Cautions
Read the following warnings and cautions before removing and
replacing any assemblies in the oscilloscope.
HAZARDOUS VOLTAGES !
Read the safety summary at the back of this book before proceeding.
Maintenance is performed with power supplied to the oscilloscope and with the
protective covers removed. Only trained service personnel who are aware of the
hazards involved should perform the maintenance. Whenever possible, perform the
procedures with the power cord removed from the oscilloscope.
AVOID ELECTRICAL SHOCK !
Hazardous voltages exist on the LCD assembly and power supply. To avoid
electrical shock:
1 Disconnect the power cord from the oscilloscope.
2 Wait at least three minutes for the capacitors in the oscilloscope to discharge
before you begin disassembly.
Read the Safety Summary at the back of this manual before you begin.
REMOVE POWER TO AVOID DAMAGE !
Remove power before you begin to remove and replace assemblies. Do not remove
or replace assemblies while the oscilloscope is turned on, or damage to the
components can occur.
AVOID DAMAGE TO ELECTRONIC COMPONENTS !
ELECTROSTATIC DISCHARGE (ESD) can damage electronic components. When
doing any of the procedures in this chapter, use proper ESD precautions. As a
minimum, you should place the instrument on a properly grounded ESD mat and
wear a properly grounded ESD strap.
