SETUP
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.
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.
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 and release the SET button to enter SETUP MODE. Once in setup 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 SET button again to adjust the
next preference. The preference set order is as follows:
DST* (Daylight Saving Time ON or OFF)
TIME ZONE (NST AST EST CST MST PST AKT HAT)
CLOCK HOUR
CLOCK MINUTE
CALENDAR MONTH
CALENDAR DATE
CALENDAR YEAR
TEMPERATURE SCALE (ºF or ºC)
BAROMETRIC PRESSURE SCALE (inHg or hPa)
*If you live in an area that observes daylight saving time, DST should be set to
ON, even if it is not currently Daylight Savings Time.
You will automatically exit SETUP MODE if no buttons are pressed for 8
seconds. Enter setup mode at any time by pressing the SET 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 “ ” 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 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 or is wall-mountable.
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 165 ft (50 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.

OPERATION
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.
Moon Phase
Track the phases of the moon, conveyed through simple lunar phase icons:
Barometric Pressure
Subtle variations in barometric pressure greatly affect the weather. This
weather station displays the current pressure with an arrow icon to indicate
the direction the pressure is trending (FALLING, STEADY, or RISING).

High & Low Records
Today’s high and low records are displayed for indoor temperature and humidity
and outdoor temperature. Today’s records automatically clear at 12:00am
midnight every day. View today’s high or low records by pressing and releasing
the “▲” or “▼” buttons. Press and release again to view current readings.
To manually clear all of today’s LOW recorded values, press and release the
“▼” button to view low records, then press and hold the “▼” button for 2
seconds. Dashes display to conrm you have cleared the LOW records.

Troubleshooting
Problem Possible Solution
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 165 ft (50 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.
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. Reinstall the battery in the outdoor sensor.
3. Reinstall the battery in the display unit.
4. Let the units sit within a couple feet of each other for
about 20 minutes to gain a strong connection.
Inaccurate forecast
• Weather Forecast icon predicts conditions for the next 12
to 24 hours, not current conditions.
• Has Learning Mode icon disappeared from the display
unit? Learning Mode must complete before forecast and
pressure will be accurate.
• Allow unit to run continuously for 33 days. Battery
removal or resetting the display unit will restart Learning
Mode. After 14 days, forecast should be fairly accurate,
however Learning Mode calibrates for a total of 33 days.
Inaccurate
temperature
or humidity
• Make sure both the display unit and sensor are placed
out of direct sunlight and away from any heat sources or
vents (see page 8).
• Make sure the display unit is positioned away from
moisture sources (see page 8).
To manually clear all of today’s HIGH recorded values, press and release the
“▲” button to view high records, then press and hold the “▲” button for 2
seconds. Dashes display to conrm you have cleared the HIGH records.
