ADDITIONAL EQUIPMENT (not included) 1) Three fresh 1. 5V AA batteries (optional for alarm clock) 2) Two fresh 1. 5V AA batteries (for remote sensor) FEATURES OF PROJECTION ALARM Operation of these features is in section III. Radio-controlled time and date Projection of time and/or remote temperature EL backlight Six modes of date/seconds/temperature display Indoor temperature Remote outdoor temperature Dual alarms Adjustable snooze ABOUT WWVB (Radio Controlled Time) 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. [. . . ] Press and release the "SET" button to confirm the calendar settings, and to advance to select either 12 or 24-hour time display. H. 12/24-HOUR SETTING/ SELECTING °F OR °C Note: Setting to the 24 hour mode (also known as Military Time) will also change the temperature to display in °C instead of °F. Press and release the "+" button to toggle between 12 and 24 hour time. Press release the "SET" button to confirm the 12/24-hour time display, and to return to normal operation. 8 IV. Radio-controlled time and date Projection of time and/or remote temperature EL backlight Six modes of date/seconds/temperature display Indoor temperature Remote outdoor temperature Dual alarms Adjustable snooze B. The projection alarm will automatically search for the time signal upon initial set-up and every night. When the signal is being received, there will be a "tower" icon flashing to the left of the time display. When the time signal has been received successfully, the tower icon will remain steady until midnight. 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. 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. 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. 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 temperature is displayed in °F or °C, depending on the time format (12 or 24 hour mode). The indoor temperature will take time to adjust to the surrounding temperature as the sensor is inside the case. If the remote temperature is placed next to the projection alarm, more often than not the temperature will not be exact with one another. 4. defect, but simply reflects the difference in measuring methods. The remote temperature is designed for changing temperature at a wide range. [. . . ] Problem: 1) Be sure correct time zone and daylight saving time are Solution: selected. "--. -" appears in outdoor temperature LCD Problem: 1) Check batteries in remote Solution: 2) If batteries are replaced in remote, the unit must be re-started. "OFL" appears in the outdoor temperature LCD Problem: 1) Remote temperature is out of range, move closer. 3) Interference from an outside source (cordless telephone, etc. ) 4) Contact La Crosse Technology.
