Set the Time, Date and 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:
Auto DST (Daylight Saving Time ON of OFF)*
CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
TEMPERATURE UNITS (ºC or ºF)
BAROMETRIC PRESSURE UNITS (hPa or inHg)
*If you live in an area that observes DST, DST should be set to ON, even if it is
not currently Daylight Saving Time.
You will automatically exit SET MODE if no buttons are pressed for 10 seconds.
Enter setup mode at any time by pressing the “ ” button.
Display Backlight Settings
This weather station’s colour display features three different lighting settings:
High (100%) brightness, Medium (60%) brightness and Low (15%) brightness.
Using battery power alone, the backlight is available momentarily for 10
seconds by pressing the Backlight button.
When display is powered with the power adapter, backlight remains on at
100% brightness. Press Backlight button once to dim to 60% brightness; press
again to dim to 15%, press a 3rd time to enter AUTO DIM mode.
NOTE: Pressing and holding the “ ” button for 5 seconds will disable the
backlight. Once any button is pressed, the backlight will return to your selected
setting.
AUTO DIM MODE: Automatically adjusts display brightness based on time of day.

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 and 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 hole 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
1 to 2 metres (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 100 m (330 ft) 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 90 cm (3 ft) away
from electronic devices (TV, computer, microwave, radio, etc.).
(330 feet)
90 cm
(100metres maximum)
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.

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 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.
Moon Phase
Track the phases of the moon, conveyed through simple lunar phase icons:
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).

Programmable Alarms
This display features programmable alarms that sound an alert to notify you
when a value (for temperature or humidity) has been reached or exceeded.
When an alarm is triggered, the display emits an audible beep and ashes data
in the affected category. You can customize the alarms by turning ON or OFF
the alarms you’d like activated or deactivated, and by inputting your own values
to trigger the alarm.

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 100 m (330 ft) of each other.
• Make sure both units are placed at least 90 cm
(3 feet) away from electronics that may interfere with
the wireless communication (such as TVs, microwaves,
computers, etc).
• Use standard alkaline batteries. 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.
Display screen
not working
• Check that the power adapter is plugged into the
display and an electrical outlet.
Outdoor
temperature
is ashing 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. Make sure the A-B-C switch on both units match.
3. Reinstall the batteries in the outdoor sensor.
4. Reinstall the batteries in the display.
5. 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 8).
• Make sure both units are positioned away from
moisture sources (see page 8).
If your AcuRite product does not operate properly after
trying the troubleshooting steps, email

Care and Maintenance
Display Care
Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives. Keep
away from dust, dirt and moisture. Clean ventilation ports regularly with a
gentle puff of air.
Outdoor Sensor Care
Clean with a soft damp cloth. Do not use caustic cleaners or abrasives.
Calibration
The indoor / outdoor temperature and humidity readings, and barometric
pressure can be calibrated on the display to improve accuracy. Calibration can
improve accuracy when sensor placement or environmental factors impact the
data accuracy.
1. To access calibration mode, press AND HOLD the “ “, “”, and “ “
buttons simultaneously for at least 5 seconds.
2. To adjust the currently selected (ashing) item, press and release the “ “
or “ “ buttons to calibrate the data value higher or lower from the actual
reading.
3. To save your adjustments, press and release the “ ” button to adjust the
next preference. The “ ” icon will remain illuminated next to calibrated
values.
The preference set order is as follows:
OUTDOOR TEMPERATURE
OUTDOOR HUMIDITY
INDOOR TEMPERATURE
INDOOR HUMIDITY
BAROMETRIC PRESSURE (must be set to MANUAL mode to calibrate)*
*To change from AUTO to MANUAL pressure mode and vice versa, press
AND HOLD the “ ” button for 10 seconds. The “ ” icon will appear
next to the barometric pressure to indicate that MANUAL mode has been
activated. Press and HOLD the “ ” button for 10 seconds to return to AUTO
mode.
After 20 seconds of inactivity, the display will save the adjustments and exit
calibration mode. Note: Calibrations will be erased if the display is reset or if
batteries are removed and the power adapter is unplugged.
