AM700 Audio Measurement Set Service Manual
Figure 6–37: Power supply and monitor board cover plate screws and cables (CRT
display version)
WARNING. The CRT is fragile and is under a high vacuum. Use a protective face
mask for safety when removing the CRT from the instrument. Place the CRT face
down on a soft surface in a protected area to prevent accidental breaking of the
CRT.
CAUTION. Be careful not to bump the connector end of the CRT against the front
casting when removing it from the instrument. The evacuation nipple is fragile
and very exposed to breaking it accidently.
8. Pull the CRT from the AM700 and set the CRT face down in front of the
instrument to allow room to disconnect the high voltage lead from the CRT.
