Install or Replace Batteries

AcuRite recommends high quality alkaline batteries for the best product performance. Heavy duty or rechargeable batteries are not recommended. The outdoor sensor requires lithium batteries in low temperature conditions. Cold temperatures can cause alkaline batteries to function improperly. Use lithium batteries in the outdoor sensor for temperatures below -4ºF / -20ºC.

Outdoor Sensor

  1. Slide off the battery compartment cover.
  2. Insert 2 x AA batteries into the battery compartment, as shown. Follow the polarity (+/-) diagram in the battery compartment.
  3. Replace the battery cover.


  1. Remove the battery compartment cover.
  2. Insert 3 x AAA batteries into the batter+
  3. y compartment, as shown. Follow the polarity (+/-) diagram in the battery compartment.
  4. Replace the battery cover.

Select Degrees Fahrenheit or CelsiusTo select between degrees Fahrenheit (ºF) or Celsius (ºC) temperature units, press the “ºC/ºF” button located on the back of the display inside the battery compartment area.


Clean the battery contacts and also those of the device prior to battery installation. Remove batteries from equipment that will not be used for an extended period of time. Follow the polarity (+/-) diagram in the battery compartment. Promptly remove dead batteries from the device. Dispose of used batteries properly. Only batteries of the same or equivalent type as recommended are to be used. DO NOT incinerate used batteries. DO NOT dispose of batteries in fire, as batteries may explode or leak. DO NOT mix old and new batteries or types of batteries (alkaline/standard). DO NOT use rechargeable batteries. DO NOT recharge non-rechargeable batteries. DO NOT short-circuit the supply terminals.

Set the Time & DatePress and HOLD the “SET” button for 3 seconds to enter set mode. Once in set mode, the preference you are currently setting will blink on the display. To adjust the currently selected (flashing) item, press and release the “▲” or “▼“ buttons (press and HOLD to fast adjust).

Placement for Maximum Accuracy

AcuRite sensors are sensitive to surrounding environmental conditions. Proper placement of both the display and outdoor sensor are critical to the accuracy and performance of this product.

Display PlacementPlace the display in a dry area free of dirt and dust. Display 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 areaprotected 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 heat sources or vents.
  • Display and outdoor sensor must be within 165 ft (50 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.).

Setup is CompleteThe sensor will now synchronize with the display. It may take a few minutes for synchronization to complete. Please refer to the troubleshooting section of this manual if anything appears to be functioning improperly.

Using the What-to-Wear Weather Forecaster

Learning Mode

Self-Calibrating Forecasting use 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.

Weather TrendSubtle variations in barometric pressure greatly impact the weather. This weather forecaster displays an arrow icon to indicate the direction the pressure is trending (FALLING, STEADY, or RISING).What-to-WearIncludes 20 different clothing recommendations based on the weather forecast:High & Low RecordsToday’s high and low records are displayed for outdoor temperature and indoor temperature and humidity. Today’s records automatically clear at 12:00am midnight every day.To view today’s HIGH (MAX) recorded values, press and release the “▲” button. The “MAX” icon appears on the display next to the high records. To view today’s LOW (MIN) recorded values, press and release the “▼“ button. The “MIN” icon appears on the display next to the low records.

Problem Possible Solution



No outdoor sensor reception

no bars

If the wireless signal indicator shows no bars:

• Relocate the display and/or the outdoor sensor.

The units must be within 165 ft (50 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).

• 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 a few minutes for display and sensor to synchronize after batteries are replaced.


Outdoor temperature is flashing or

showing dashes

Flashing of the outdoor temperature is generally an indication of wireless interference.

1.  Bring both the sensor and display indoors and remove at least one battery from each.

2.   Reinstall the battery in the outdoor sensor.

3.   Reinstall the battery in the display.

4.   Let the units sit within a couple feet of each other for a few minutes to gain a strong connection.


Inaccurate temperature or humidity

•  Make sure both the display and sensor are placed out of direct sunlight and away from any heat sources or vents (see page 6).

• Make sure both units are positioned away from moisture sources (see page 6).




Inaccurate forecast

•  The Weather Forecast icon predicts conditions for the next 12 to 24 hours, not current conditions.

• Has Learning Mode icon disappeared from the display? 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 will restart Learning Mode. After 14 days, forecast should be fairly accurate, however Learning Mode calibrates for a total of 33 days.

Display screen not working • Check that the batteries are installed correctly. Batteries may need to be replaced.
