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

choices for both the sensor and

the display unit in order for the

units to synchronize.

Install or Replace Batteries

AcuRite recommends high quality

alkaline or lithium batteries 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.

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.

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 re, 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.

Atomic Clock

AcuRite atomic clocks use a radio-controlled signal (RCC) to synchronize to the

correct time broadcast by the National Institute of Standards and Technology

(NIST) Radio Station WWVB, located near Fort Collins, Colorado. WWVB

broadcasts the current time and date with split-second accuracy.

The atomic clock and calendar will maintain the correct time and date, and

automatically update for daylight saving time to provide the most accurate

timekeeping standard possible.

Please note: Signal reception is normally better at night and when the weather

is clear. The atomic signal generally takes a few hours to synchronize, so it is

important to manually set the time and date after powering on the display.

Set the Time & Date

The display unit will automatically start in SET mode after batteries have been

installed. Enter SET mode at any time by pressing the "SET" button, located

on the back of the display unit. 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 "SET" 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

You will automatically exit SET MODE if no buttons are pressed for 30 seconds.

Enter setup mode at any time by pressing the "SET" button.

* If you live in an area that observes Daylight Savings Time, DST should be set

to ON, even if it is not currently Daylight Savings Time.

Select Degrees Fahrenheit or Celsius

To select between degrees Fahrenheit (ºF) or Celsius (ºC) temperature units,

press the "ºF/ºC" button located on the back of the display unit.

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 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 Forecaster

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.

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.

If your AcuRite product does not operate properly after trying the

troubleshooting steps, visit www.AcuRite.com or call

(877) 221-1252 for assistance.

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

• Make sure both the display unit and sensor are

placed out of direct sunlight and away from any heat

sources or vents (see page 7).

Atomic signal or time

syncing problems

• Press the SIGNAL button on the back of the display to

manually search for the atomic clock signal.
