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

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. Take note of the A-B-C
switch setting inside the battery
compartment.
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.

WIND UNITS (MPH or KPH)
You will automatically exit SET MODE if no buttons are pressed for 10 seconds.
Enter setup mode at any time by pressing the “ ” 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.
Display Backlight Settings
This weather station’s color display features three different lighting settings:
High (100%) brightness, Medium (60%) brightness and Low (30%) brightness
Using battery power alone, the backlight is available momentarily for 10
seconds by pressing the “ ” button.
When display is powered with the power adapter, backlight remains on
at 100% brightness. Press “ ” button once to dim to 60% brightness;
press again to dim to 30%, press a 3rd time to enter “AUTO DIM” mode.
AUTO DIM appears below time.

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.
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 speed measurement.

3-in-1 Sensor Installation Guidelines
INSTALLATION HEIGHT Mount the sensor at a minimum height of 5 feet (1.5 meters)
off the ground, in an open area. Higher is better for wind measurements - the
National Weather Service recommends 33 feet high!
MOUNTING OPTIONS The included mounting bracket is designed to screw directly
onto wooden posts or surfaces that are 2”x4” or larger. The sensor can also be
mounted directly to 3/4” steel or
PVC pipe (available at hardware
stores and home centers).
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. Fasten mounting base to a post
or railing using 2 screws.
Pipe Mount
1. Insert pipe 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 pipe.
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.
