Get Started

1. Remove round battery cover to access clock movement and

battery compartment(s).

2. Insert 1 AA battery into the movement at the center of the clock.

3. OPTIONAL: For extended battery life, install two additional

batteries, one on either side of the movement.

4. Select your specific time zone by firmly pressing the correct time

zone button once. Replace battery cover.

5. The default time zone is Pacific Time. If the clocks sets and the

hours are off, hold the correct time zone button for 5 seconds to

correct.

Position Clock

•Indoor:Choose a location 6 feet or more from electronics such as

cordless phones, wireless gaming systems, televisions, microwaves,

routers, baby monitors, etc., which can prevent signal reception.

•Position near an exterior wall that faces Ft. Collins, Colorado for

WWVB time signal reception.

•The antenna is available for signal reception when the front or back

of the clock faces Colorado.

•Outdoor:Choose a location with an overhang to protect the clock

from the overhead sun or standing snow or rain.

•A shaded location will prevent inaccurate temperature readings.

Mount the clock on a wall with the hanging hole on the back of the

clock. Be sure the battery cover is on snug.

Manual Set Time

On rare occasions in certain areas, the clock may not be able to receive

the radio controlled time signal due to the strength of the signal or the

geographic location. In this case, the clock can be set manually and

used as a regular quartz wall clock.

Note:Allow up to five nights for the clock to receive the WWVB signal

before manually setting the time.

Set the clock manually:

1. Remove battery for 15 minutes and press the Time Set tab 20 times.

2. After 15 minutes, insert the battery and allow the clock to spin to

12:00, 4:00 or 8:00.

3. Hold the Time Set Tab and the hands will spin. Continue holding

until the correct time is achieved.

Note: You can only set the clock manually for about 2 minutes after the

battery is inserted. If the clock receives the WWVB time signal, this

signal will override manually set time.

Temperature and Humidity

The La Crosse Technology®atomic wall clock has two analog sensors

that measure surrounding temperature and humidity. The temperature

information is displayed in degrees Fahrenheit and Celsius, and humidity

data is displayed in percentage.

The thermometer and hygrometer have been calibrated at the factory.

To check the sensors accuracy, tune to your local weather forecast

information broadcast for the latest weather information. The sensors

may be adjusted.

To manually adjust the sensors, gently turn the temperature or humidity

sensor adjustment on the back of the clock until desired setting has been

reached. Daylight Saving Time

The National Institute of Standards and Technology and WWVB encode

a special DST “bit” in the WWVB transmission for DST. Your clock will

read this information and automatically advance the hands one hour in

the spring and eleven hours in the fall.

Arizona: If you live in an area that does not recognize DST, you must

press the DST button one time only to turn OFF.

Signal Interference

In some cases, the signal is affected by weather conditions and electrical

interferences, or the location of the clock itself may result in poor

reception. If the clock has not synchronized to the correct time within a

few days of activation, you may need to move the clock to a different

location.
