DETAILED SETUP GUIDE
I. BATTERY INSTALLATION
A. The alarm clock requires one AA
Alkaline battery. Open up the
compartment insert the battery to activate.
It will start searching for a signal and set
to the correct time and date, usually not
until overnight.

II. PROGRAMMING
A. SETTING THE TIME
There are two methods by which the time
and date can be set: 1) Automatically via
WWVB reception, or 2) Manually.
B. WWVB (Radio-Controlled Time)
This method requires you to do nothing,
except wait for the signal to be received,
and to select a time zone. Reception
usually takes approximately 6-10 minutes
during optimal conditions. The best
conditions for reception is at night,
between midnight and 6:00 am—when
there is less atmospheric interference. To
keep your time as accurate as possible, the
alarm clock conducts a WWVB search
every night between these hours, and
overrides any manually set time. The
WWVB tower icon (appearing in the
TIME LCD) will flash when a signal-
search is in progress and a signal is being
received, and will remain steady when the
signal has been received. If the WWVB
time has not been received after 10

5
minutes of battery installation, you may
manually set the time or leave the time
function alone (reception will occur
regardless).
About Radio Controlled Time signal,
WWVB:
The NIST (National Institute of Standards
and Technology—Time and Frequency
Division) WWVB radio station is located
in Ft. Collins, Colorado, and transmits the
exact time and date signal continuously
throughout the United States at 60 kHz.
The signal can be received up to 2,000
miles away through the internal antenna in
the alarm clock. However, due to the
nature of the Earth’s Ionosphere,
reception is very limited during daylight
hours. The alarm clock will search for a
signal every night when reception is best.
The WWVB radio station derives its signal
from the NIST Atomic clock in Boulder,
Colorado. A team of atomic physicists is
continually measuring every second, of
every day, to an accuracy of ten billionths
of a second per day. These physicists

6
have created an international standard,
measuring a second as 9,192,631,770
vibrations of a Cesium-133 atom in a
vacuum.
C. PROGRAMMING
(includes manual time setting)
**To end the programming mode at any
time, simply press the SNOOZE button

III. SETTING THE ALARMS
La Crosse Technology’s travel alarm clock
has two separate alarms that can be set.
Each alarm has a distinctive sound and
operate independently.
A. Press and hold the “ALM1” (or
“ALM2” key) key for two seconds to enter
the setting mode. The alarm time will
flash. Press the “HOUR” key to advance
the hour of the alarm, and press the “MIN”
key to advance the minutes of the alarm. If
no button is pressed within fifteen seconds,
the alarm will set and will activate, and
the clock will revert to the normal
operating screen. The picture below shows
both alarms activated.
B. To activate/deactivate the alarm, press
“Alarm 1”
activated
“Alarm 2”
activated

10
the “ALM1” or “ALM2” key once,
depending on which alarm needs to be
activated.
C. When the alarm is sounding, pressing
the “SNOOZE” will turn it off for the time
that was selected in the programming
mode (section II.A.2.c.). The snooze is
activated by pressing back on the entire
unit while the cover is open. The actual
button is on the bottom of the unit and is
pressed by the cover when pushed back. If
the setting is “0”, the alarm will turn off
for 24 hours. During the snooze period, the
lower screen will show a countdown until
the alarm will sound again. If the snooze
bar is pressed again during the original
snooze period, the period will be reset.
Once the period is finished, the alarm will
sound again. Pressing any key other than
the snooze key will turn off the alarm for
24 hours.

IV. OPERATING SCREENS
A. The exact time will always be displayed
in the upper portion of the screen, and the
US map will show when the time zone is
set to the continental US (with the time
zone selected showing in black). The
lower portion of the screen has five
different screens that can be selected. The
default is “DAY, MONTH, DATE” as
shown below.
B. Press the “MODE” key to select which
screen to show. It will change in order as
follows:
1. DAY MONTH DATE
2. MONTH DATE YEAR
3. SECONDS

4. ALARM 1 TIME
5. ALARM 2 TIME
C. While in non-alarm mode, pressing the
“SNOOZE” bar will show the “ALARM1”
and “ALARM2” briefly in the lower
section.
V. TRAVELING
A. When traveling, it will only be
necessary to change to the appropriate
time zone. Please note that the clock will
only search for a signal when it is set
between “GMT-4 and GMT-10.The alarm
clock will set to any time zone from
“GMT” to “GMT-12”. Outside this range,
it will only be necessary to set the hour to
the correct hour, leaving the time zone set
to your local time zone. For example, if
you are traveling to Hong Kong, you will
need to manually set the hour to the local
time. When the clock is back in the US, it
will search for a signal and set to the
proper time according to the time zone
selected.

TROUBLESHOOTING
NOTE: For problems not solved, please
contact La Crosse Technology via e-mail or
phone, or visit our website,
www.lacrossetechnology.com
Problem: The time and date will not set
initially.
Solution: It usually takes overnight before
the clock can receive the signal due to the
interference the sun has on the WWVB
signal. Wait overnight for the signal.
Solution: Computer monitors and
televisions can cause interference with the
signal reception. Please keep the clock at
least six feet from electrical sources.
Solution: In some areas of the US, in
particular on the East and West coasts, the
signal is very weak. It may take up to 72
hours before a good signal is received. The
reception can be helped by placing the clock
in a window facing Colorado, with the back
towards Colorado.
Solution: Be sure the time zone is set to a
US time zone.
