Battery Installation
Low battery warning:
When the “low battery warning” symbol appears on the
display, it means the batteries will need to be replaced soon
(see Figure 1).
The thermometer still operates properly until both symbols
of “Lo” and “ ” are shown on the display.
Battery installation:
1. Gently slide the battery cover downward to open it (see
Figure 3).
2. Remove the old batteries and discard them safely and
properly.
3. Insert two new AAA alkaline batteries, taking care to
insert them in the correct position as indicated.
4. Gently slide the battery cover back into position.
