The NIST atomic clock is one of the most precise clocks in the world, accurate to 10 billionths of one second. The NIST’s atomic clock contributes to the international group of clocks calculating the Coordinated Universal Time (UTC)—the official world time. RADIO CONTROLLED TIME A radio controlled time device is often confused with an atomic clock. However, a radio controlled time device receives its time information from the atomic clock each day through an internal antenna. The radio controlled time device searches for an exact time signal every night when the signal from the WWVB is the strongest. The signal can be received up to 2,000 miles away through a radio controlled time device. For more information regarding the NIST, WWVB, atomic clock, and radio controlled time, please visit the NIST official website: 3 I. QUICK SET-UP GUIDE Hint: Use good quality alkaline batteries and avoid rechargeable batteries. 1. We recommend beginning the set-up procedure at night when the WWVB signal is easiest to receive. 2. It is also highly recommended to set the projection alarm in a window or other area free of interference in the area of your home that is closest to Colorado (the source of the WWVB signal). NOTE: The above steps are not required but can help the projection alarm receive the signal faster. 3. Install the batteries in the projection alarm clock. 4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES. NOTE: It is important to not press any buttons after inserting batteries as this will interrupt the WWVB search sequence. In this time the display will show the indoor temperature. If the station does not display the indoor temperature after the 15 minutes please retry the set-up as stated above. After the indoor temperature displays for 15 minutes you may place the projection alarm in your desired location. To complete the set-up of your temperature station after the 15 minutes have passed, please follow the steps beginning on page 6. 4 II. DETAILED SET-UP GUIDE battery cover AC adapter receptacle A. BATTERY INSTALLATION 1. Remove the battery cover on the backside of the projection alarm. 2. Observe the correct polarity, and install 2 AA batteries. 3. In addition to or instead of installing batteries, the AC adapter can be used. Simply plug the adapter into the receptacle on the underneath side of the alarm clock, and then plug in the adapter. 4. Replace the battery cover. 5. The projector will activate and remain on if the alarm clock is plugged in. If only batteries are used, the projector will only be activated when a button is pressed. The projection is a red light, not harmful under normal usage, although care should be taken to not look directly into the light. Notes: • After the batteries have been installed, the LCD will activate, and you will hear a beep. • The indoor temperature will be displayed, and the time will appear as “12:00 AM”. • The WWVB search is automatically initiated, and a tower icon appears and flashes with the time colon (no tower icon will appear if the WWVB is too weak to be detected, and the time display will start from 12:00 AM). • While the WWVB search is being conducted various numbers will appear in the time display. • After 15 minutes, the projection alarm will either display the WWVB time, or discontinue the search if the time is not found. If the search is cancelled the time will continue from 12:00 AM. • The projection alarm will conduct a WWVB search every hour until the first signal is found. • Once the WWVB time is found, a search is automatically conducted nightly at midnight. • If the signal is found at midnight, the tower icon will remain, if not, another search will take place every hour (until 6:00 AM) until the signal is found successfully. • If no signal is found during this period, the tower icon will not appear, and the clock will search again at midnight the next night. • The radio-controlled time receiver is located on the bottom side of the projection alarm. When using the AC adaptor be sure to keep the adapter cord away from the bottom side of the unit; as it can cause weakened reception of the radio controlled signal. 5 III. PROGRAM MODE To enter the Program Mode, hold down the “MODE/MIN” button for 3 seconds, until the time zone flashes at the bottom of the display. The Program Mode Guide is laid out in a manner that allows you to program each function separately, or you can follow the instructions entirely to program the projection alarm. Complete programming is usually done for the initial set-up, and will require you to skip step 1 and 2 of programming sections D-H. To exit the setting mode simply wait approximately 10 seconds for the projection alarm to automatically return to normal operation. A. PROGRAMMING SEQUENCE 1. Time Zone Setting 2.
