Disassembly
1. Power off the instrument. Remove the two screws that
secure the battery cover on the back of the console.
Open battery cover and remove batteries, if installed.
2. On the back of the console at the corners, pull back the
rubber gasket and loosen the four screws that hold the
top and bottom of the case together. The screws should
remain captive under the gasket. Gently separate the
two halves of the enclosure.
3. Attach the anti-static wrist strap snugly around your
wrist and attach the clip to earth ground (e.g., a com-
puter chassis that is plugged in or other appliance
chassis that is plugged in). This will help prevent dam-
age from static electricity during installation.
4. Disconnect the power cable connector (circled below)
from the main PC board.
