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 unit 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.

PLEASE DISPOSE OF OLD OR DEFECTIVE BATTERIES IN AN ENVIRONMENTALLY SAFE
WAY AND IN ACCORDANCE WITH YOUR LOCAL LAWS AND REGULATIONS.
BATTERY SAFETY: Clean the battery contacts and also those of the device prior to battery installation. Remove batteries from equipment which is not to
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 re, 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.
Display Unit Setup

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 unit will automatically start in SET mode after batteries have been
installed. Enter SET mode at any time by pressing the “SET” button, located
on the back of the display unit. 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.
* If you live in an area that observes Daylight Savings Time, DST should be set
to ON, even if it is not currently Daylight Savings 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 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.).
Setup is Complete
The sensor will now synchronize with the display unit. 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 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.

showing dashes
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.

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 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
temperature
• 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).
Atomic signal or time
syncing problems
• Press the SIGNAL button on the back of the display to
manually search for the atomic clock signal.
