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. 10 C. Projection of Time 1. When plugged into an AC outlet, the projection alarm can continuously project the time. 2. When operating on batteries alone the projection alarm will only project when a button is pressed. 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 direction of the display can be rotated 360° in 90° increments by pressing the directional button. There is no display on the LCD that signifies the direction. 5. The projector case can be rotated 180° to further help orient the projected display. 6. The intensity of the projection can be adjusted to three different settings as well as turned “off” by pressing the light Intensity button. When turned off, the projection will only come on when a button is pressed. The intensity cannot be set for the projected display when set to “off”. 7. When only batteries are used, the intensity setting is set to “off” with no other options. .......... Light Intensity Projection Direction D. LCD Light 1. The projection alarm has an LCD light designed for night viewing. This will light up for 2 seconds whenever a button is pressed. 2. The LCD light cannot be turned on constantly; this would drain the batteries and burn out the light. E. Indoor Temperature 1. The projection alarm measures indoor temperature with an internal sensor. 2. This temperature is displayed in °F or °C, depending on the time format (12 or 24 hour mode). When in 12-hour format the temperature will be in °F. When in 24-hour mode the temperature will be in °C. 3. The indoor temperature will take time to adjust to the surrounding temperature as the sensor is inside the case. 11 12 F. Time Alarm The projection alarm has two separate alarms for time, “ALM1” and “ALM2”. The alarms have a different sound; ALM1 increases in volume after 25 seconds, and again after 50 seconds. ALM2 is a constant volume. The total duration is 96 seconds for each alarm. 1. Setting the Alarm a) Press and hold “ALM1” or “ALM2” for two seconds until the alarm time is flashing. b) Press and release “ALM1/HOUR” to advance the hour. c) Press and release “ALM2/MIN” to advance the minute. d) The time will display “PM” if set to PM, and nothing if set to AM. e) “(((1)))” or “(((2)))” will be displayed to the right of the time when the alarm is activated. f) The projection alarm will revert to normal operation when no buttons are pressed for 15 seconds. g) The alarm is now set and activated. 2. Activating/Deactivating the Alarm a) After entering the alarm setting mode the alarm is activated (either ALM1 or ALM2). b) To toggle between activating and deactivating the alarm, press either the “ALM1” or “ALM2” briefly. c) “(((1)))” or “(((2)))” will be displayed to the right of the time display when the alarm is activated. d) When the snooze bar is pressed, the display will scroll through the Alarm 1 and Alarm 2 times in the lower right. 3. Turning Alarm Off (While Sounding) a) While either alarm is sounding press and release the “SNOOZE” bar to disable the alarm for the set duration (Section II. D.). b) If the duration is set to “0” the alarm will be disabled for 24 hours. c) After the “SNOOZE” bar is pressed the lower left will display the time remaining on the snooze. d) The “SNOOZE” bar may be pressed at any time to restart the snooze duration. e) To disable the alarm for 24 hours press any button other than “SNOOZE” or projection keys. Alarm 2 activated G. Changing the Display Mode (Day, Seconds, and Temperature) There are six possible display modes to view the day, seconds, and temperature. To change the display (starting at the default of day, date, year): 1. Press and release the “MODE/+” button. 2. The display should now show month, day, year. 3. Press and release the “MODE/+” button again. 4. The display will now show seconds. 5. Press and release the “MODE/+” button again. 6. The display will now show alarm1 time. 7. Press and release the “MODE/+” button again. 8. The display will now show alarm2 time. 9. Press and release the “MODE/+” button again. 10. The display will now show indoor temperature. 11. Press and release the “MODE/+” button again. 12....
