QUICK SETUP

1. The alarm clock is packed in the closed position. To open, flip open the cover.

2. 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. After the time and date are set, set to the correct

time zone.

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 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”

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.
