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

Install or Replace Batteries
AcuRite recommends high quality
alkaline or lithium batteries in
the outdoor 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. Take
note of the A-B-C switch
setting inside the battery
compartment for display unit
setup.
2. Insert 2 x AA batteries into
the battery compartment, as
shown. Follow the polarity
(+/-) diagram in the battery
compartment.
3. Replace the battery cover.

Intelli-Time®Clock
Intelli-Time products are pre-programmed with the correct time and date.
Intelli-Time technology instructs the time and date to set themselves. All you
need to do is select your Time Zone and Daylight Saving Time preferences. The
clock will then automatically set itself and change for Daylight Saving Time.
Set the Time, Date & Units
Press the “ ” button, located on the back of the display unit, 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 “ “ or
“ “ buttons (press and HOLD to fast adjust).
To save your adjustments, press and release the “ ” button again to adjust
the next preference. The preference set order is as follows:
TIME ZONE ( PST MST CST EST AST HAST AKST)
DST (Daylight Saving Time ON or OFF)*
CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
TEMPERATURE UNITS (ºF or ºC)
PRESSURE UNITS (inHg or hPa)
*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 10 seconds.
Enter setup mode at any time by pressing the “ ” button.
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 “BACKLIGHT” button.
When display is powered with the power adapter, backlight remains on at
100% brightness. Press “BACKLIGHT” button once to dim to 60% brightness;
press again to dim to 30%, press a 3rd time to enter “AUTO DIM” mode.
AUTO DIM MODE: Automatically adjusts display brightness based on time of day & year.
MARCH 11- NOVEMBER 4 6:00 a.m. - 9:00 p.m. = 100% brightness
9:01 p.m. - 5:59 a.m.= 30% brightness
NOVEMBER 5 - MARCH 10 7:30 a.m. - 7:00 p.m.= 100% brightness
7:01 p.m. - 7:29 a.m. = 30% brightness

Placement for Maximum Accuracy
AcuRite sensors are sensitive to surrounding environmental conditions. Proper
placement of both the display unit and outdoor 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.
Display unit stands upright for tabletop use.
Outdoor 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 hang holes or 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
• To ensure accurate temperature measurement, place units out of direct
sunlight and away from any heat sources or vents.
• Display unit and outdoor sensor must be within 330 ft (100 m) of each other.
• To maximize wireless range, place units away from large metallic items, thick
walls, metal surfaces, or other objects that may limit wireless communication.
• To prevent wireless interference, place both units at least 3 ft (.9 m) away
from electronic devices (TV, computer, microwave, radio, etc.).
Setup is Complete
The sensor will now synchronize with the display unit. It may take a few
minutes for synchronization to complete. Please refer to the troubleshooting
section of this manual if anything appears to be functioning improperly.

Using the Weather Station
Learning Mode
Self-Calibrating Forecasting uses 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
No outdoor sensor
reception
no bars
If the wireless signal indicator shows no bars:
• Relocate the display unit and/or the outdoor 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 -4ºF/-20ºC). Do not
use heavy duty or rechargeable batteries. NOTE: It
may take up to 20 minutes for display unit and sensor
to synchronize after batteries are replaced.
Display screen
not working
• Check that the batteries are installed correctly.
Batteries may need to be replaced.
• Reset display by pressing the RESET button, located
on the back of the display unit. Date and time will
need to be entered after a reset.
Outdoor
temperature
is ashing or
showing dashes
Flashing of the outdoor temperature is generally an
indication of wireless interference.
1. Bring both the sensor and display unit indoors and
remove at least one battery from each.
2. Make sure the A-B-C switch on both units match.
3. Reinstall the battery in the outdoor sensor.
4. Reinstall the battery in the display unit.
5. Let the units sit within a couple feet of each other
for about 20 minutes to gain a strong connection.
