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)

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.

Placement for Maximum Accuracy
(100 meters)
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 wallmountable.
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.

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.

conrm you have cleared the record.
Troubleshooting
Problem Possible Solution
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.
• Check that the batteries are installed correctly.
Batteries may need to be replaced.
• Reset the 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.

Troubleshooting
Problem Possible Solution
Outdoor

Inaccurate forecast
Inaccurate
temperature
or humidity
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.
• 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.
• 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 both units are positioned away from
moisture sources (see page 8).

away from dust, dirt and moisture. Clean ventilation ports regularly with a
gentle puff of air.
Outdoor Sensor Care
Clean with a soft damp cloth. Do not use caustic cleaners or abrasives
Calibration
Calibrate Temperature & Humidity
The indoor / outdoor temperature and humidity readings can be calibrated on
the display unit to improve accuracy. Calibration can improve accuracy when
sensor placement or environmental factors impact your data accuracy.
1. To access calibration mode, press AND HOLD the “ ”, “ ”, and “ ”
buttons (located on the back of the display unit) for at least 5 seconds.
2. Once in calibration mode, the preference you are currently setting will blink
on the display.
3. Press the “ “ or “ “ buttons to calibrate the data value higher or lower
from the actual reading.
4. Press the “ ” button to conrm the calibration adjustment.
The “ ” icon will remain illuminated next to calibrated values.
5. The next adjustable data will begin ashing, indicating it is ready to be
calibrated. Repeat Steps 1 - 4 to calibrate additional data.
After 20 seconds of inactivity, the display will save the adjustments and exit
calibration mode. Note: Calibrations will be erased if the display is reset or if
batteries are removed and the power adapter is unplugged.
Calibrate Barometric Pressure
The weather station default pressure mode is “AUTO”. In auto mode, the
pressure will calibrate itself over a 14 day Learning Mode. Barometric pressure
can be manually calibrated:
1. Press AND HOLD the “ ” button (located on the back of the display unit)
for at least 10 seconds to enter manual pressure mode.
2. The un-calibrated pressure will be displayed. Press AND HOLD the “ ”,
“ ”, and “ ” buttons for at least 5 seconds.
12
3. Press the “ “ or “ “ buttons to calibrate the pressure higher or lower.
4. Press the “ ” button to conrm the calibration adjustment.
Note: The “ ” icon will remain illuminated next to the calibrated value.
After 20 seconds of inactivity, the display will save your adjustments and exit
calibration mode. Note: Calibration will be erased if the display is reset or if
batteries are removed and the power adapter is unplugged
To exit manual pressure mode and return to auto mode press and hold the
“ “ button for at least 10 seconds.
Replace Intelli-Time Battery
This device comes with
a factory installed
“CR2032” coin-cell
battery that powers the
Intelli-Time memory.
If the display unit sits
without power for a long
period of time, the coincell battery may need to
be replaced to ensure
the Intelli-Time feature
functions properly.
Install battery with “+” positive
terminal facing OUT.
