BATTERY SAFETY: 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.

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.
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 & Units
Press and release the “ ” button, located on the front of the display, 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 “ ” button again to adjust the next
preference. The preference set order is as follows:
TIME ZONE (EST, CST, MST, PST, AKT, HAT, AST)
AUTO CHANGE for DST? (Daylight Saving Time ON or OFF)*
CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
TEMPERATURE UNITS (ºF or ºC)
BAROMETRIC PRESSURE UNITS (hPa or inHg)
ATOMIC CLOCK FUNCTION (ON or OFF)
*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.
You will automatically exit SETUP MODE if no buttons are pressed for 10 seconds. Enter
setup mode at any time by pressing the “ ” button.

Placement for Maximum Accuracy
AcuRite sensors are sensitive to surrounding environmental conditions. Proper
placement of both the display and the 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
(1 to 2 meters) 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 (90 cm) away
from electronic devices (TV, computer, microwave, radio, etc.).

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

OPERATION
Using the Weather Station
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.

Barometric Pressure
Subtle variations in barometric pressure greatly affect the weather. This
weather station displays the current pressure with an arrow icon to indicate
the direction the pressure is trending (FALLING, STEADY, or RISING).
High & Low Records
Today’s high and low records are displayed for indoor and outdoor temperature
and humidity. Today’s records automatically clear at 12:00am midnight
every day. View today’s high and low records by pressing and releasing the
“” button.
To manually clear a HIGH or LOW record, press and HOLD both the “ “ and
““ buttons simultaneously for 3 seconds while viewing the record you wish to
clear. Dashes display to conrm you have cleared the record.
