Thermometer Display Icons and Alarms
The thermometer communicates to the user using the LCD display and audible beeps. When a probe cover is installed or the
batteries have been changed, the thermometer completes a system reset. The thermometer also performs a self-test to ensure
that the device is working correctly.

If System Error "1" and System Error "2" are shown, the room conditions are too unstable for the device to be used. Allow the
device to stabilize for 20 minutes before use.
If System Error 1 is shown, the thermometer has an internal
memory checksum error (self-diagnostic test failure). Install
a new probe cover to reset the unit. If the system error does
not clear, contact the service center.
If System Error 2 is shown, the thermometer is out of
calibration (e.g. a calibration variable is outside of the
expected range). Contact the service center.
For any other System Error, install a probe cover to reset the unit. If the system error does not clear, contact the service center.

Display Mode
The LCD shows the low battery icon. The low battery icon will stay on until the
batteries are changed or until the dead battery display appears. Once the low
battery icon is shown, about 100 readings can be taken.
The LCD shows the dead battery display. When any button is pressed this display
will flash 3 times and then the LCD will turn OFF. Once the dead battery icon is
shown, the batteries must be changed before the unit can be used.
