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 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 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
a) Press the SET button. The US map and time zone will flash (“-5” is the default). The
time zone is displayed according to “GMT”; please see below table for explanation.
Press the “+” key to move the time zone West one hour until it reaches the your time
zone, then press the SET key to set the time zone and move to the next programming
step.
b) “DST On” will flash. Press the “+” key to toggle between the Daylight Saving Time
ON or OFF (for places that do not follow Daylight Saving Time changes). Press the
SET key.

c) “Sno” will show at the bottom of the screen, and a number will flash at the top. This
is the setting for the length of the alarm snooze. Press the “+” key to advance the
length from 0 (no snooze)) to 59 minutes. This sets the time the alarm is silenced after
pressing the SNOOZE key while the alarm is sounding. Press the SET key.
d) The hour will now flash. Press the “+” key to advance to the correct hour; be sure to
note the correct am/pm setting (“PM” will show for pm setting, nothing for the am
setting). Press the SET key.
e) The minutes will now flash. Press the “+” key to advance the minutes. By holding
the “+” key, the minutes will advance in five minute increments. Press the SET key.
f) The year will now flash. Press the “+” key to advance to the correct year. Press the
SET key.
g) The month will now flash. Press the “+” key to advance to the correct month. Press
the SET key.
h) The date will now flash. Press the “+” key to advance to the correct day. Press the
SET key.
i) The day of the week will now flash (Sun, Mon, etc.). Press the “+” key to advance to
the correct day of the week. Press the SET key.
j) “12” or “24” will now flash. Press the “+” key to select either 12 –hour or 24-hour
(military time). The programming is now complete.

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 the “ALM1” or “ALM2” key once, depending
on which alarm needs to be activated.
“Alarm 2”
activated
“Alarm 1”

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.
