For example Eastern Time will display “ET” when the Eastern Time Zone is selected 5. Press and release the “SET” button to confirm the time zone setting and to advance to the DST (Daylight Saving Time) setting. -4h Atlantic Time -5h Eastern Time (default setting) -6h Central Time -7h Mountain Time -8h Pacific Time -9h Alaskan Time -10h Hawaiian Time -11h, -12h Next two time zones West of HAW 0h Greenwich Mean Time -1h, -2h, -3h Three time zones West of GMT E. DST (DAYLIGHT SAVING TIME) SETTING 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”. 1. Hold down the “MODE/MIN” button for 3 seconds, the time will flash in the Time LCD. 2. Press and release the “SNOOZE” button twice to advance to the DST setting. 3. “DST” will appear in the indoor temperature/humidity LCD and “ON” or “OFF” will flash in the time LCD. 4. Press and release the “MODE/MIN” button to toggle between DST ON and OFF.. 5. Press and release the “SNOOZE” button to confirm the DST setting and complete the set-up sequence. 7 IV. FEATURES & OPERATIONS A. FEATURES 1. Radio-controlled time 2. Projection of time and/or remote temperature 3. LED backlight 4. Display of indoor temperature/humidity or alarm time 5. Indoor temperature and humidity 6. Remote outdoor temperature 7. Time alarm B. RADIO-CONTROLLED TIME 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. 7. For more detail, visit To listen to the NIST time, call (303) 499-7111. This number will connect you to an automated time, announced at the top of the minute in “Coordinated Universal Time”, which is also known as Greenwich Mean Time (GMT). This time does not follow Daylight Saving Time changes. After the top of the minute, a tone will sound for every second. 8. It is possible that your projection alarm may not be exactly on the second due to the variance in the quartz. However, the clock will adjust the quartz timing over the course of several days to be very accurate; under 0.10 seconds per day. C. PROJECTION OF TIME AND REMOTE TEMPERATURE 1. When plugged into an AC outlet, the projection alarm will continuously project the time and remote temperature. 2. When operating on batteries alone, the projection alarm will only project when the snooze button is pressed or the alarm is sounding. 3. The projection will auto-focus for display from three to six feet away. A dark surrounding will be necessary to clearly see the projection. 4. The projection alarm will automatically toggle between the time and outdoor temperature when projecting; either when the “SNOOZE” button is pressed or continuously when using the AC adaptor. 5. The direction of the display can also be rotated 360° in 90° increments by pressing the directional button. There is no display on the LCD that signifies the direction. 6. The projector case can be rotated 180° to further help orient the projected display. 8 D. EL BACKLIGHT 1. The projection alarm has an EL backlight designed for night-viewing. This will light up for 4 seconds whenever the snooze button is pressed. 2. The EL backlight cannot be turned on constantly; this would drain the batteries. E. INDOOR TEMPERATURE 1. The projection alarm measures indoor temperature with an internal sensor. 2. This temperature is displayed in °F. 3. The indoor temperature will take time to adjust to the surrounding temperature as the sensor is inside the case. 4. If the remote temperature is placed next to the projection alarm, more often than not the temperature will not be exact with one another. This is not a defect, but simply reflects the difference in measuring methods. The remote temperature is designed for chang...
