Sensor Setup
Set the A-B-C Switch
The A-B-C switch is located inside the
battery compartment. Slide to set the
channel to A, B or C.
NOTE: If being used with a
companion product that has an A-B-C
channel, you must select the same
letter choice for both the sensor and
the product it is being paired with in
order for the units to synchronize.
Install or Replace Batteries
AcuRite recommends high quality
alkaline or lithium batteries in
the wireless sensor for the best
product performance. Heavy duty
or rechargeable batteries are not
recommended.
The sensor requires lithium batteries
in low temperature conditions. Cold
temperatures can cause alkaline
batteries to function improperly. Use
lithium batteries in the sensor for
temperatures below -4ºF / -20ºC.
1. Slide off the battery compartment
cover.
2. Insert 4 x AA batteries into the
battery compartment, as shown.
Follow the polarity (+/-) diagram
in the battery compartment.
3. Replace the battery cover.

Placement for Maximum Accuracy
AcuRite sensors are sensitive to surrounding environmental conditions. Proper
placement of the sensor is critical to the accuracy and performance of this
product.
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 hanger, or by using string
(not included) to hang it from a suitable location, like a well
covered tree branch. The best location is 4 to 8 feet above the
ground with permanent shade and plenty of fresh air to circulate
around the sensor.
Important Placement Guidelines
• Sensor must be within 330 feet (100 meters) of a companion unit
(sold separately).
MAXIMIZE WIRELESS RANGE
Place unit away from large metallic items, thick walls, metal surfaces, or other
objects that may limit wireless communication.
PREVENT WIRELESS INTERFERENCE
Place unit at least 3 feet (90 cm) away from electronic devices (TV, computer,
microwave, radio, etc.).
LOCATE AWAY FROM HEAT SOURCES
To ensure accurate temperature measurement, place sensor out of direct
sunlight and away from any heat sources.
LOCATE AWAY FROM HUMIDITY SOURCES
To ensure accurate humidity measurement, locate sensor away from humidity
sources. Avoid installing the sensor near indoor pools, spas, or other bodies of
water. Water sources may impact humidity accuracy.
Lightning Detection
The sensor detects cloud-to-cloud, cloud-to-ground and intra-cloud lightning.
When lightning is detected, the sensor will beep and the strike indicator will
ash for each of the rst 10 strikes. After 10 strikes, the sensor will enter silent
mode but will continue to ash. The sensor will stay in silent mode for 2 hours
after the last lightning detection.
