USE AN EXTERNAL FAN TO AVOID OVERHEATING COMPONENTS !
When you remove the oscilloscope cover and main shield, use an external fan to
provide continuous air flow over the heat sinks. Air flow over the heat sinks is
reduced when the cover and main shield are removed, which leads to higher than
normal operating temperatures. Have the fan blow air across the system board
where the heat sinks are located. Otherwise, damage to the components can
occur.
If the cover of a 7000 Series oscilloscope is removed but the main shield remains
installed and the bottom holes are not blocked, the instrument will cool properly.
HAZARDOUS VOLTAGES EXIST — HIGH VOLTAGE IS PRESENT ON POWER
SUPPLY HEAT SINKS !
The power supply heat sinks of the oscilloscope 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!
