6. Gently rock and pull the modules apart.
7. Refer to Figure 4.3 on page 144 to locate the battery on the
controller board. Hold the controller board with the
battery side facing down a few inches above a table or
bench top. Pull up on the battery’s spring tab and allow the
battery to slip out of its housing and to the table top. Do
not use a metal object (screwdriver, etc.) to remove the
battery; this can short the + and – terminals. Replace
battery with Duracell DL2032 (3 volt) only; contact
Watlow Anafaze. Use of another battery may present a
risk of fire or explosion. See
Battery Safety on page 11 for
safety instructions.

children.
9. Install the new battery.
10. Reassemble the controller.

locked.
