The A-B-C switch is located inside
the battery compartment. It can
be set to A, B or C. However,

the display unit in order for the
units to synchronize.

AcuRite recommends high quality
alkaline or lithium batteries for

the best product performance.

Heavy duty or rechargeable

batteries are not recommended.

The sensor requires lithium
batteries in low temperature

conditions. Cold temperatures
can cause alkaline batteries
to function improperly. Use
lithium batteries in the sensor for
temperatures below -4ºF / -20ºC.

1. Slide off the battery

compartment cover. Take
note of the A-B-C switch

setting inside the battery

compartment for part 2.

2. Insert 2 x AA batteries into

the battery compartment, as
shown. Follow the polarity
(+/-) diagram in the battery

compartment.

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

Atomic Clock

AcuRite atomic clocks use a radio-controlled signal to synchronize to the
correct time broadcast by the National Institute of Standards and Technology
(NIST) Radio Station WWVB, located near Fort Collins, Colorado. WWVB
broadcasts the current time and date with split-second accuracy.

The atomic clock and calendar will maintain the correct time and date, and
automatically update for daylight saving time to provide the most accurate
timekeeping standard possible.

Please note: Signal reception is normally better at night and when the weather
is clear. The atomic signal generally takes a few hours to synchronize, so it is
important to manually set the time and date after powering on the display.

Set the Time & Date

Press the “SET” button, located on the back of the display unit, to enter SET
MODE. Once in set mode, the preference you are currently setting will blink on
the display.

To adjust the currently selected (ashing) item, press and release the “+” or
“–“ buttons (press and HOLD to fast adjust).

To save your adjustments, press and release the “SET” button again to adjust
the next preference. The preference set order is as follows:

TIME ZONE ( PST MST CST EST AST HAST AKST)
DST (Daylight Saving Time ON or OFF)
CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR

You will automatically exit SET MODE if no buttons are pressed for 30 seconds.
Enter setup mode at any time by pressing the “SET” button.

Select Degrees Fahrenheit or Celsius

To select between degrees Fahrenheit (ºF) or Celsius (ºC) temperature units,
press the “ºF/ºC” button located on the back of the display unit.

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

No outdoor sensor

reception

no bars

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).

• 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.

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

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

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.

• 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).

the troubleshooting steps, visit www.AcuRite.com or call
