DETAILED SETUP GUIDE
I. BATTERY INSTALLATION
A. The battery compartment is located on
the back of the travel alarm.
B. Remove the battery cover.
C. Insert one AA battery (alkaline
recommended) into the battery
compartment making sure to observe the
correct polarity.
D. Replace the battery cover and do not
press any buttons for 10 minutes while the
travel alarm searches for the WWVB time
signal.

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

5
signal has been received. If the WWVB
time has not been received after 10
minutes of battery installation, you may
manually set the time or wait for the
WWVB reception.
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

6
accuracy of ten billionths of a second per
day. These physicists have created an
international standard, measuring a second
as 9,192,631,770 vibrations of a Cesium-
133 atom in a vacuum. For more
information please see the NIST website at
www.boulder.nist.gov/timefreq/stations/wwvb.htm.

“ALM2” key) key for two seconds to
enter the setting mode.
b) The alarm time will flash.
c) Press and release the “HOUR” key to

the minutes of the alarm.
Note: If no button is pressed within
fifteen seconds, the alarm will set and
activate, and the clock will revert to the
normal operating screen. The picture
below shows both alarms activated.
Activating the Alarms
To activate/deactivate the alarm, press
and release the “ALM1” or “ALM2” key
once, depending on which alarm needs to
be activated.
Activating the SNOOZE function
When the alarm is sounding, pressing the
top of the unit gently backwards will
“Alarm 1”
activated
“Alarm 2”
activated

12
activate the snooze for the time that was
selected in the programming mode. 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
is activated 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 will turn off the alarm for 24
hours.
III. 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.

13
B. Press and release 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.

14
IV. 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 sometimes 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.

16
Solution: Be sure the time zone is set to a
US time zone.
