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

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 3-in-1 sensor requires lithium
batteries in low temperature
conditions. Cold temperatures
can cause alkaline batteries to
function improperly. Use lithium
batteries in the 3-in-1 sensor for
temperatures below -4ºF / -20ºC.
1. Press the release lever and
pull off the lower housing of
the sensor.
2. Remove the battery
compartment cover.
3. Insert 4 x AA batteries into
the battery compartment, as
shown. Follow the polarity
(+/-) diagram in the battery
compartment.
4. Replace the battery cover and
lower housing of the sensor.

Atomic Clock
AcuRite atomic clocks use a radio-controlled signal 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
Press and hold the “SET” button, located on the front of the display unit, for
3 seconds 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 “+”
button (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 ( EST AST HAT AKT PST MST CST )
DST (Daylight Saving Time ON or OFF)*
CLOCK HOUR
CLOCK MINUTE
CALENDAR YEAR
CALENDAR MONTH
CALENDAR DATE
*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 30 seconds.
Enter setup mode at any time by pressing and holding the “SET” button.
Select Measurement Units
To select between U.S. standard units or imperial units, press the “SCALE”
button.
Measurement U.S. Standard Units Imperial Units
Temperature Degrees Fahrenheit (ºF) Degrees Celsius (ºC)
Barometric Pressure inHg (inches of mercury) hPa (Hectopascal)
Wind Speed Miles per hour (mph) Kilometers per hour (kph)

Placement for Maximum Accuracy
AcuRite sensors are sensitive to surrounding environmental conditions. Proper
placement of both the display unit and the 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. To
ensure accurate temperature measurement, place out of direct
sunlight and away from heat sources or vents. Display unit stands
upright for tabletop use or is wall-mountable.
3-in-1 Sensor Placement
The 3-in-1 sensor is designed to remain outdoors all year long.
Choose an open location with no obstructions above or around
the sensor for the most accurate measurements.
Important Placement Guidelines
Display unit 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.).
LOCATE AWAY FROM HEAT SOURCES
Position sensor away from heaters, air conditioners, chimneys, exhaust vents,
asphalt and concrete (surfaces that radiate heat).
LOCATE AWAY FROM HUMIDITY SOURCES
Avoid installing the sensor near pools, spas, or other bodies of water. Water
sources may impact humidity accuracy.
LOCATE AWAY FROM SPRINKLER HEADS
DO NOT install the sensor where it will be sprayed by a sprinkler system. This
may force water inside the sensor.
LOCATE AWAY FROM WIND OBSTRUCTIONS
DO NOT mount the sensor with obstructions around it.
Consider a location that is a wide open area, with few
structures around to ensure accurate wind measurement.

3-in-1 Sensor Installation Guidelines
INSTALLATION HEIGHT Mount the sensor at least 5 feet (1.5 meters) off the
ground (higher is better for wind measurement) in an open area. Secure to
fence post, 4”x4” wood, 3/4” pole, etc. (not included)
LEVEL INSTALLATION Use a bubble level (not included) to ensure level
installation for accurate wind measurement.
Top or Side Mount
1. Insert the mounting base into
the hole on the bottom of the
sensor.
2. Use one of the screws included
in the hardware bag to fasten
the lower sensor housing to the
mounting base.
3. Make sure the sensor is level
using a bubble level.
4. Fasten mounting base to a post
or railing using 2 screws.
Pole Mount
1. Insert pole (we recommend 3/4”
schedule 40 PVC / 25.8 mm O.D.,
not included) or similar item all the
way into the hole on the bottom of the
sensor. Note: Mounting base is not
used.
2. Use one of the screws included in the
hardware bag to fasten the lower
sensor housing securely to the pole.
3. Make sure the sensor is level using a
bubble level.
The 3-in-1 sensor is now ready to use.
Basic Setup is Complete
The 3-in-1 sensor will now synchronize with the display unit. It may take a few
minutes for synchronization to complete. If both or one of the units appear to
be functioning improperly, please refer to the troubleshooting section.
