Placement for Maximum Accuracy
AcuRite sensors are sensitive to surrounding environmental conditions. Proper
placement of both the display and the 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. To ensure accurate
temperature measurement, place out of direct sunlight and away from heat
sources or vents. Display stands upright for tabletop use.
Important Placement Guidelines
Display and sensor must be within 330 feet (100 m) of each other.
MAXIMIZE WIRELESS RANGE
Place units away from large metallic items, thick walls, metal surfaces, or other
objects that may limit wireless communication.
PREVENT WIRELESS INTERFERENCE
Place both units at least 3 feet (.9 m) away from electronic devices (TV, computer,
microwave, radio, etc.).
Using The Weather Center
Learning Mode
Self-Calibrating Forecasting use 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
Problem Possible Solution
No outdoor sensor
reception
no bars
• Relocate the display and/or the 3-in-1 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 -20ºC/-4ºF). 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.
• Synchronize the units:
1. Bring both the sensor and display indoors and remove
power adapter/batteries from each.
2. Reinstall batteries in outdoor sensor.
3. Reinstall power adapter in display.
4. Let the units sit within a couple feet of each other for a few
minutes to gain a strong connection.
Outdoor
temperature
is ashing or
showing dashes
Flashing of the outdoor temperature may be an indication of
wireless interference:
• Make sure the A-B-C switch in the battery compartments of
both the display unit and sensor are switched to the same
letter. You may choose A, B or C; but both units must match
to sync up. Sometimes changing to a different channel can
help.
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.

Problem Possible Solution
Inaccurate
temperature or
humidity
• Make sure both the display unit and 3-in-1 sensor are
placed away from any heat sources or vents (see page 6).
• Make sure both units are positioned away from moisture
sources (see page 6).
• Make sure 3-in-1 sensor is mounted at least 5 ft off of
the ground.
• Calibrate indoor and outdoor temperature and humidity
(see page 10).
Inaccurate wind
readings
• What is wind reading being compared to? Pro weather
stations are typically mounted at 30 ft high or more. Make
sure to compare data using a sensor positioned at the
same mounting height.
• Check location of the sensor. Ensure it’s mounted a
minimum of 5 ft in the air with no obstructions around it
(within several feet).
•Ensure wind cups are spinning freely. If they hesitate or stop
try lubricating with graphite powder or spray lubricant.
Display screen
not working
• Check that the power adapter is plugged into the display
and an electrical outlet.
• Check that the batteries are installed correctly.
Batteries may need to be replaced.
• Reset the display by pressing the RESET button, located on
the back of the display unit in the battery compartment.
Date and time will need to be entered after a reset.
Inaccurate barometric
pressure
It may take up to 14 days for the pressure to calibrate to
your location.
The unit lost power
or batteries were
changed and the
time is not correct
The Intelli-Time battery needs to be replaced
(see page 10). Once the new battery is installed,
time and date will need to be set manually.
Troubleshooting

Care & 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.

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 at least 10 seconds. The display indicates
the current pressure mode selected,“AUTO” or “MANUAL”.
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.

Replace Intelli-Time®Clock Battery
Intelli-Time technology is powered by a pre-installed coin-cell battery that stores
the time and date settings. The battery has a shelf life of several years. To
replace the Intelli-Time battery:
1. Locate the coin cell battery compartment door on the back of the display.
Unscrew and remove the
compartment cover.
2. Insert 1 x CR2032 coin
cell battery into the
battery compartment,
as shown. Install battery
with “+” positive terminal
facing OUT.
3. Screw in the battery
cover.
