Placement for Maximum Accuracy
AcuRite sensors are sensitive to surrounding environmental conditions. Proper
placement of both the display unit and outdoor sensor are critical to the
accuracy and performance of this product.
Display Unit Placement
Place the display unit in a dry area free of dirt and dust.
Display unit stands upright for tabletop use or is wall-mountable.
Outdoor Sensor Placement
Sensor must be placed outside to observe outdoor conditions.
Sensor is water resistant and is designed for general outdoor
use, however, to extend its life place the sensor in an area
protected from direct weather elements.
Hang the sensor using the integrated hang holes or hanger, or
by using string (not included) to hang it from a suitable location,
like a well covered tree branch. The best location is 4 to 8 feet
above the ground with permanent shade and plenty of fresh air
to circulate around the sensor.
Important Placement Guidelines
• To ensure accurate temperature measurement, place units out of direct
sunlight and away from any heat sources or vents.
• Display unit and outdoor sensor must be within 330 ft (100 m) of each other.
• To maximize wireless range, place units away from large metallic items, thick
walls, metal surfaces, or other objects that may limit wireless communication.
• To prevent wireless interference, place both units at least 3 ft (.9 m) away
from electronic devices (TV, computer, microwave, radio, etc.).

minutes for synchronization to complete. Please refer to the troubleshooting
section of this manual if anything appears to be functioning improperly.

OPERATION
Using the Weather Forecaster
Learning Mode
Self-Calibrating Forecasting uses a unique algorithm to analyze changes in
pressure over a time period (called Learning Mode) to determine your altitude.
After 14 days, the Learning Mode icon disappears from the display screen. At
this point, the self-calibrated pressure is tuned in to your location and the unit is
ready for superior weather prediction.
Weather Forecast
AcuRite’s patented Self-Calibrating Forecasting provides your personal forecast
of weather conditions for the next 12 to 24 hours by collecting data from
the sensor in your backyard. It generates a forecast with pinpoint accuracy -
personalized for your exact location.

Troubleshooting
If the wireless signal indicator shows no bars:
• Relocate the display unit and/or the outdoor sensor.
The units must be within 330 ft (100 m) of each other.
•
Make sure both units are placed at least 3 feet (.9 m)
away from electronics that may interfere with the
wireless communication (such as TVs, microwaves,
computers, etc).
No outdoor sensor
reception
no bars
• Use standard alkaline batteries (or lithium batteries in
sensor when temperature is below -4ºF/-20ºC). Do not
use heavy duty or rechargeable batteries. NOTE: It
may take up to 20 minutes for display unit and sensor
to synchronize after batteries are replaced.
• Check that the batteries are installed correctly.
Batteries may need to be replaced.
• Reset the unit by pressing the reset button located on
the back of the display. Time and date will need to be
entered after a reset.

2. Make sure the A-B-C switch on both units match.
3. Reinstall the battery in the outdoor sensor.
4. Reinstall the battery in the display unit.
5. Let the units sit within a couple feet of each other
for about 20 minutes to gain a strong connection.
• Weather Forecast icon predicts conditions for the next
12 to 24 hours, not current conditions.
• Has Learning Mode icon disappeared from the
display unit? Learning Mode must complete before
forecast and pressure will be accurate.
• Allow unit to run continuously for 33 days. Battery
removal or resetting the display unit will restart
Learning Mode. After 14 days, forecast should be
fairly accurate, however Learning Mode calibrates for
a total of 33 days.
Inaccurate forecast
• Make sure both the display unit and sensor are
placed out of direct sunlight and away from any heat
sources or vents (see page 7).
