SETUP
Set the A-B-C Switch
The A-B-C switch is located inside
the battery compartment. It can
be set to A, B or C. However,
you must select the same letter
choices for both the sensor and
the display in order for the units
to synchronize.
Install or Replace Batteries
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.
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.

Atomic Clock
AcuRite atomic clocks use a radio-controlled signal (RCC) 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
The display will automatically enter SET MODE after the unit has powered on.
Enter SET MODE at any time by pressing the “SET” button, located on the back
of the display. 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 SET MODE at any time by pressing the “SET” button.
* If you live in an area that observes Daylight Saving Time, DST should be set
to ON, even if it is not currently Daylight Saving Time.
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.
Display Backlight Settings
This weather station’s color display features three different lighting settings:
High (100%) brightness, Medium (60%) brightness and Low (15%) brightness.
When the display is powered with the power adapter (recommended), the
backlight remains on at 100% brightness by default. Adjust the backlight
brightness by pressing and releasing the “+” or “_” buttons.
Using battery power alone, the backlight is available momentarily for 10
seconds by pressing and releasing the “+” or “_” buttons.

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 Placement
Place 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 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 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.).
Setup is Complete
The 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 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 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 a few
minutes for display and sensor to synchronize after batteries
are replaced.

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

If your AcuRite product does not operate properly after trying the
troubleshooting steps, visit www.AcuRite.com or call
[phone] for assistance.
Inaccurate forecast
• 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.
Inaccurate
temperature
• Make sure both the display and sensor are placed out
of direct sunlight and away from any heat sources or
vents (see page 8).
Atomic signal or time
syncing problems
• Press the SIGNAL button on the back of the display to
manually search for the atomic clock signal.
