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.
