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 units to synchronize.
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 for step 2.
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.

2. Insert 3 x AA alkaline batteries
into the battery compartment,
as shown. Follow the polarity
(+/-) diagram in the battery
compartment.
3. Replace the battery cover.
PLEASE DISPOSE OF OLD OR DEFECTIVE BATTERIES IN AN ENVIRONMENTALLY SAFE
WAY AND IN ACCORDANCE WITH YOUR LOCAL LAWS AND REGULATIONS.
BATTERY SAFETY: Clean the battery contacts and also those of the device prior to battery installation. Remove batteries from equipment which is not to 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 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.
This AcuRite 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: 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 for 5 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 (flashing) item, press 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 (PST MST CST EST)
DST (Daylight Saving Time ON OR OFF)
CLOCK HOUR
CLOCK MINUTE
CALENDAR YEAR
CALENDAR MONTH
CALENDAR DATE
You will automatically exit SET MODE if no buttons are pressed for 30 seconds. Enter
basic 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.
Please note: The “WIND SPEED” history chart only displays data in “mph”.
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 speed 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, 2’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.
