Battery Charge
Use the battery charge symbols to gauge the approximate level of charge left on the
batteries.
Notes
When in low battery mode, the thermometer does not store values. “Err”
appears on the display if attempted.
J
Batteries are at 5 %. Before taking further readings, the batteries must
be changed.
Changing the Batteries
Note
The batteries should be replaced in less than one minute after removal to
avoid manually re-initializing the thermometer clock and date.
To install or change the two AA batteries (see Figure 8):
1. Slide the locking tab on the battery door to the “unlock” position and then open the
handle.
2. Insert the batteries noting their correct polarity.
3. Close and lock the handle.
