BATTERIES

The thermometer incorporates visual low battery indication

as follows.

Battery OK: Measurements are possible.

Battery Low: Battery needs to be replaced, measurements

are still possible.

Battery Exhausted: Measurements are not possible.

When the low battery icon indicates the battery is low, the

batteries should be replaced immediately with a CR2032

lithium cell battery using the below steps.

The battery is located under the twist cover in the rear of the

device. Using a coin or flat head screwdriver, twist the cover

counterclockwise. Remove the cover and remove the bat-

tery. Insert one CR2032 (3V) lithium cell battery according to

the diagram located in the battery slot.

It is important to allow the thermometer to power off

before replacing the batteries otherwise the thermometer

may malfunction. Dispose of used batteries promptly and

keep away from children.
