1.The year digits will start flashing on LCD2. Select the desired year by use of the + key.
2.Press and release the SET key to switch to the “Month Setting”.
MONTH SETTING
1.The month digits on LCD2 will start flashing. Set the desired month by use of the + key.
2.Press and release the SET key to move to the mode “Date Setting”.
DATE SETTING
1.The digits for the date will start flashing on LCD2 (Default setting 1). Set the desired date by use of the + key.
Note: The date can only be set in conjunction with the selected month. For example, it is not possible to set the date 30 if the month of February is selected.
2.Press and release the SET key to move to “Weekday setting”.
WEEKDAY SETTING
1.The weekday symbols will be displayed on LCD2 in the pre-set language and flashing. Set the desired weekday by use of the + key.
2.Press and release the SET key to enter the mode “ºC or ºF Temperature Setting”.
°C OR °F TEMPERATURE SETTING
1.The characters “°F” or “°C” will start flashing on LCD2 (Default setting °F). By use of the + key select “°C” for temperature display in degrees Celsius or “°F” for degrees Fahrenheit.
2.Press and release the SET key to exit the setting mode and switch back to the normal display mode.
EXIT THE MANUAL SETTING MODES
•To return to the normal display mode from anywhere in manual setting mode simply press the ALM key anytime.
•If no keys are pressed for at least 15 seconds in setting mode, the radio-controlled clock will automatically switch back to normal display mode.
CHANGING THE DISPLAY MODE (DAY, ALARM AND SECONDS)
There are 3 possible display modes to view the day, alarm and seconds.
The indoor temperature/outdoor temperature/month&date/weekday are the default.
To change the display:
1.Press the + key. The display should now show the indoor temperature/ outdoor temperature/ alarm/ weekday.
2.Press the + key a second time and the display will now show the indoor temperature/ outdoor temperature/ seconds/ weekday.
3.Press the + key a third time and the display will return to the normal display.
ALARM SETTING
To enter into the alarm setting mode:
1.Hold the ALM key for 4 seconds. The hour digits start flashing.
2.Press and release the + key to set the hour.
3.Press and release the ALM key to set the minutes. The minute digits start flashing.
4.Press and release the + key to set the minutes.
5.Press and release again the ALM key to exit the Alarm setting mode or wait for 15 seconds automatic timeout.
TO DEACTIVATE THE ALARM:
Alarm icon (((•))) (ON)
The alarm will be automatically ON when the alarm time is set. To deactivate the alarm (OFF), press and release once the ALM key in normal mode display. The alarm icon will disappear, the 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
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 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).
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.
