zone button once. Replace battery cover.

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 the DST indicator to 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.
