Procedure:
1. Disassemble the analyzer as follows:
a. Remove the battery cover and the batteries, uncovering one of
the cover hold-down screws.
b. Remove and set aside all four cover hold-down screws.
c. With the analyzer on its back, remove the front cover, laying it
face down to the left of the body.
d. Carefully remove the circuit board, slipping off the battery con-
nector on top, and then laying the circuit board face down in the
top cover.
2. Gently pull CO sensor out of its socket (see Figure 5-3).
3. Properly dispose of the old CO sensor (see the instruction sheet that
comes with the new sensor).
4. It is recommended that the CO sensor gasket (see Figure 5-4) be

discard. Remove the paper backing from the new gasket and adhere
it to the case in the same position as the old one.
