1. Hold down the “SET” button for 1 second (the selected time zone will
flash), press the “SET” button 9 more times, until the “12” or “24”
hour time display flashes in the time LCD.
2. Press and release the “Mode/+ ” button to toggle between 12 and 24-
hour time.
3. Press and release the “SET” button to confirm the 12/24-hour time
display, and to return to normal operation.
III. FEATURES & OPERATIONS
A. FEATURES
1. Radio-controlled time and date
2. Projection of time and/or remote temperature
3. EL
backlight
4. Six modes of date/seconds/temperature display
5. Indoor
temperature
6. Remote outdoor temperature
7. Dual
alarms
8. Adjustable snooze
9. Forecast icon based on changing air pressure
B. RADIO-CONTROLLED TIME AND DATE
1. The projection alarm will automatically search for the time signal
upon initial set-up and every night.
2. When the signal is being received, there will be a “tower” icon
flashing to the left of the time display.
3. When the time signal has been received successfully, the tower icon
will remain steady until midnight.
4. 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 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 Projection
alarm.
5. Due to the nature of the Earth’s Ionosphere, reception is very limited
during daylight hours. The Projection alarm will search for a signal
every night when reception is best.
6. The WWVB radio station receives the time data 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.
