WARNING
HAZARDOUS VOLTAGES EXIST — REMOVE POWER FIRST !
The procedures described in this section are 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 procedures. Whenever possible, perform the procedures with the power
cord removed from the oscilloscope. Read the safety notice at the back of this book before proceeding.

HEAT SINKS !
The power supply heat sinks of the 6000L Series oscilloscopes are at a high potential. This presents an
electric shock hazard. Protect yourself from electric shock by keeping this area covered or by not coming
in contact with the heat sinks when the power cord is attached to the oscilloscope!
CAUTION
