away from dust, dirt and moisture. Clean ventilation ports regularly with a
gentle puff of air.
Calibration
The indoor / outdoor temperature and humidity readings, and barometric
pressure can be calibrated on the display unit to improve accuracy. Calibration
can improve accuracy when sensor placement or environmental factors impact
the data accuracy.

T
”, “SET”, and “
V
”
buttons simultaneously for at least 5 seconds.

“ buttons to calibrate the data value higher or lower from the actual
reading.
3. To save your adjustments, press and release the “SET” button to adjust the
next preference. The “ ” icon will remain illuminated next to calibrated
values.
The preference set order is as follows:
OUTDOOR TEMPERATURE
OUTDOOR HUMIDITY
INDOOR TEMPERATURE
INDOOR HUMIDITY
BAROMETRIC PRESSURE (must be set to MANUAL mode to calibrate)*
*To change from AUTO to MANUAL pressure mode and vice versa, press
AND HOLD the “SET” button for at least 10 seconds. The display indicates
the current pressure mode selected,“AUTO” or “MANUAL”.
After 10 seconds of inactivity, the display will save the adjustments and exit
calibration mode. Note: Calibrations will be erased if the display is reset or if
batteries are removed and the power adapter is unplugged.
