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.
