5.2.2 Disassembly Instructions

Turn the instrument off and disconnect the temperature
probe before removing the bottom cover.
When disassembling the instrument, handle the PC
board by the edges. Body oil, dirt, and moisture can
degrade the circuit performance. Keep the PC board
clean and free of contaminants.
1. Place the unit face down on a bench or other similar surface and
remove the screws from the bottom cover.
2. Separate the bottom cover form the rest of the instrument by grasp-
ing the top of the case (above the display) and gently lifting it
away from the display.
3. Remove the battery.
4. Remove the standoff that secures the PC board to the case.
(It is located in the center of the PC board.)
5. Remove the switch cover for the Model 866 and for the
Model 865.
6. Lift the PC board out of the top cover (front panel).
When removing the LCD from the PC board, be careful not to
spread the four retaining hooks on the clear plastic bezel too far.
Plastic bezel hooks may fracture.
7. The LCD is held in place on the PC board by a shock resistant-
mounting and is assembled as shown in Figure 5-2.
8. To reassemble the unit, reverse the above procedure.
