BATTERY INSTALLATION AND REPLACEMENT
Remove the cover
Hold the sensor firmly by the hex area at the bottom. Rotate the top cover counter-clockwise from the locked
index mark on the cover to the unlocked mark. Carefully lift the cover off in a straight direction to avoid
damage to internal components.
Avoid touching any portion of the PC boards or electronic components.
Insert the battery
Follow these steps:
•
Push the battery removal strip into the battery compartment so the new battery will sit on top of it.
•
Hold the battery spacer so the narrow end covers the negative (-) battery contact electrode (nearer
to the hex end of the device).
•
Insert the battery (negative end first) so it traps the spacer between the negative battery contact and
the negative electrode on the battery.
•
Slowly push the positive electrode end of the battery into the battery compartment until it’s fully
seated.
•
Holding the battery in place, slowly extract the spacer from the negative electrode.
•
A one second flash from the LED will indicate that the battery has been inserted properly.
