The transmitter uses 2 x AA,1.5V batteries. To install and replace the batteries, please follow
the steps below:
1. Remove the battery cover by pushing down towards bottom of transmitter and sliding
cover out.
2. Insert the batteries, observing the correct polarity (see marking inside battery
compartment).
3. Replace the battery cover on the unit.
TO INSTALL / REPLACE BATTERIES IN THE RADIO-CONTROLLED CLOCK
The radio-controlled clock uses 2 x AA,1.5V batteries. To install and replace the batteries,
please follow the steps below:
1. Insert finger or other solid object in the space at the bottom center of the battery
compartment and lift up to remove the cover.
2. Insert batteries observing the correct polarity (see marking inside battery compartment).
3. Replace compartment cover.
DO NOT SET THE CLOCK.
REPLACING BATTERY(S):
For best performance, batteries should be replaced at least once a year to maintain the best
running accuracy. Ensure that the batteries used are new and the correct size.
Please help in the preservation of the environment and return used batteries
to an authorized depot.

SETUP:
Alkaline batteries are recommended for use in both units.
NOTE: Do not set the clock until the outdoor temperature is displayed.
1. Place batteries in the outdoor transmitter first, then into the radio-controlled clock. DO
NOT PRESS ANY BUTTONS FOR 30 MINUTES.
2. After 15 minutes both the Indoor and Outdoor areas on your clock should have a
temperature showing. If not, remove both sets of batteries, wait 15 minutes and repeat
step one.
3. After 15 minutes have elapsed, the WWVB time code reception will automatically start.
This reception typically takes 10 minutes in good conditions. If after 10 minutes the
WWVB time has not been received, use the “SET” key to enter the set-up mode to
manually set the Time, Time Zone and Date (see manual settings below). The clock will
continue to search for WWVB each hour between 12am and 6am. When the clock has
successfully connected with WWVB, it will override the manually set time and date.
Note:
In the event of changing batteries of the unit, ensure that the batteries do not spring free from
the contacts. Press any button 20 times with the batteries removed. Always wait at least 10
minutes after removing batteries before reinserting, otherwise start up and transmission
problems may occur.
WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time
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 atomic clock. However, due to the nature
of the Earth’s Ionosphere, reception is very limited during daylight hours. The atomic 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 continually
measures every second of every day to an accuracy of ten billionths of a second a 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. This atomic clock regulates the WWVB
transmitter.
After 15 minutes the WWVB tower icon in the clock display will start flashing in the top center of
the LCD. This indicates the clock has detected a radio signal and is trying to receive it. When
6
the time code is received, the WWVB tower becomes permanently lit and the time will be
displayed.
If the tower icon flashes, but does not set the time or the WWVB tower does not appear at all,
then please take note of the following:
Recommended distance to any interfering sources like computer monitors or TV sets is a
minimum of 6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit close to a window and/ or point its
front or back towards the Fort Collins, Colorado, transmitter.
During nighttime, the atmospheric disturbances are usually less severe and reception is
possible in most cases. A single daily reception is adequate to keep the accuracy
deviation below 1 second.
Note:
In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time can be manually set (please refer to notes on Manual time setting).
FUNCTION KEYS
The radio-controlled clock has four easy to use keys:
SET key : To enter into the set mode for the following functions: time zone, DST
ON/OFF (daylight saving time), language, hour, minute, year, month, date,
weekday, ºC or ºF temperature
+ key : To toggle between the month and date, alarm and seconds display
To change any values in manual set mode
ALM key : To enter into the alarm set mode
To activate/deactivate the alarm
SNZ key : To activate the snooze function during alarm
To exit manual setting modes
LCD SCREEN DESCRIPTIONS
The radio-controlled clock's LCD is divided into 2 sections and once the batteries are inserted,
all the segments will light up briefly before displaying the information for time, date, indoor and
outdoor temperatures.

* When the signal is successfully received by the Weather Station, the icon will be switched on.
(If not successful, the icon will not be shown in LCD) So the user can easily see whether the
last reception was successful (icon on) or not (icon off).
If the signal reception is not successful on the first frequency (915MHz) for 30 seconds, the
frequency is changed to 920MHz and the learning is tried another 30 seconds. If still not
successful the reception is tried for 30 seconds on 910MHz. This will also be done for re-
synchronization.
MANUAL SETTINGS
Note: If the radio-controlled clock has already successfully received the WWVB time
signal and displays the correct time and date, then the Manual settings can be skipped.
After completion of the above described procedures in “Setting-up” the manual setting modes
can be entered by pressing and holding the SET key for 3 seconds. The following settings can
now be programmed:
Time zone
DST ON/OFF

TIME ZONE
The time zone can be set between the 0 to –12 hour or Greenwich Mean Time (GMT) range in
LCD2. To do this:
1. The time zone (LCD2) will start flashing (Default setting "-5“). Select the desired time zone by
pressing and releasing the + key.
Time zone settings: -12, -11, HAW, ALA, PST, MST, CST, EST, ATL, -3, -2, -1, GMT
2. Press and release the SET key to enter the “DST Settings“.
DST (DAYLIGHT SAVING TIME)
1. The ON digit will start flashing on LCD1. Set the DST ON or OFF by pressing the + key.
2. Press and release the SET key to enter the “Language Settings“.
Note:
The DST default is “ON”, meaning that the WWVB will automatically change the time according
to Daylight Saving Time in the spring and fall. For areas that do not recognize DST changes
(Arizona and parts of Indiana) turn the DST “OFF”.
LANGUAGE
The weekdays can be displayed in LCD1 with the pre-set languages: (US) English, Spanish (E)
and French (F).
1. Set the desired language for the weekday display in LCD1 by use of the + key.
2. Press and release the SET key to enter the mode “Manual Time Settings”.
MANUAL TIME
In case the radio-controlled clock is not able to detect the WWVB-signal (disturbances,
transmitting distance, etc.); the time can be manually set. The clock will then work as a normal
Quartz clock.
Note: the time will be displayed with an additional “ ”PM for the time from 12:00 noon until
11:59.
1. The hour digits will start flashing on LCD1.
2. Set the desired hours by pressing and releasing the + key followed by pressing the SET
key.
9
3. Now the minute digits will start flashing.
4. Set the desired minutes by pressing and releasing the + key. If the + key is held, the units
will increase by 5.
5. Press and release the SET key to move to the “Year Setting”.
Note: The unit will still try to receive the signal every day despite it being manually set. When it
does receive the signal, it will change the manually set time into the received time. During
reception attempts the WWVB tower icon will flash. If reception has been unsuccessful, then
the WWVB tower icon will not appear but reception will still be attempted the following hour.
WWVB time reception takes place from 12:00 am through 6:00 am each day (attempts WWVB
reception every full hour within this time frame). When the time signal is received for example at
1:00 am, the radio-controlled clock will not attempt to receive the WWVB signal for the
remaining hours until 6:00 am. Therefore, the next signal attempt will take place between 12:00
am and 6:00 am the next day. The other times WWVB reception takes place, are upon setup
and after manual time set exiting mode. Reception is generally not possible during daylight
hours due to the interference of the sun.
YEAR
The year can be selected sequentially from 2001 to 2029 and will then start over again (default
setting 2006). The year will only appear in the manual setting mode.
1. The year digits will start flashing on LCD2. Select the desired year by use of the + key.

alarm is now off.
SNOOZE SETTING
The snooze can only be activated during alarm time for a snooze duration of 10 minutes by
pressing the SNZ key on the back of the clock.
WEATHER FORECAST
The weather forecasting feature is estimated to be 75% accurate. The weather forecast is
based solely upon the change of air pressure over time. In areas where the weather is not
affected by the change of air pressure, this feature will be less accurate.
Weather Icons
There are 3 possible weather icons that will be displayed in the LCD 2:
Sunny—indicates that the weather is expected to improve (not that the weather will be sunny).
Sun with Clouds—indicates that the weather is expected to be fair (not that the weather will be
sunny with clouds).
Clouds with Rain—indicates that the weather is expected to get worse (not that the weather
will be rainy).
Alarm icon ((())) (ON)
12
The weather icons change when the unit detects a change in air pressure. The icons change in
order, from “sunny” to “partly sunny” to “cloudy” or the reverse. It will not change from “sunny”
directly to “rainy”, although it is possible for the change to occur quickly. If the symbols do not
change then the weather has not changed, or the change has been slow and gradual.
Weather Tendency Arrows
Other possible displays in LCD 2 are 2 weather tendency arrows, one that points up (on the left
side of the forecast) and one that points down (on the right side of the forecast). These arrows
reflect current changes in the air pressure. An arrow pointing up indicates that the air pressure
is increasing and the weather is expected to improve or remain good. An arrow pointing down
indicates that the air pressure is decreasing and the weather is expected to become worse or
remain poor. No arrow means the pressure is stable.
OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the radio-controlled clock every 4 seconds.
The radio-controlled clock will update the temperature display every 20 seconds.
The range of the outdoor temperature transmitter may be affected by the temperature. At cold
temperatures the transmitting distance may be decreased. Please bear this in mind when
positioning the transmitter. Also the batteries may be reduced in power during periods of
extreme cold temperatures.
915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The radio-controlled clock will receive the temperature data within 4 seconds. If the temperature
data is not being received 2 minutes after setting up (or the display shows “- - -”), then please
check the following points:
1. The distance of the radio-controlled clock or outdoor temperature transmitter should be at
least 6 feet (2 meters) away from any interfering sources such as computer monitors or
TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the same
signal frequency (915MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 915MHz signal frequency can also
cause interference.
