BATTERY REPLACEMENT
Only use 3.6V lithium batteries. Before replacing the battery, remove the
data logger from the PC. Follow steps 1 through 4 below:
1. Use a pointed object (eg. a small screwdriver) to open the casing.
Lever the casing off in the direction of the arrow.
2. Pull the data logger from the casing.
3. Replace/insert the battery into the battery compartment observing
the right polarity. The two displays briey light up for control purposes
(alternating green/yellow/green).
4. Slide the data logger back into the casing until it snaps into place.
Now the data logger is ready for programming.
