Note: After the batteries have been installed all the LCD’s (Liquid Crystal
Display) will briefly light up. Then the indoor temperature, the date as “1/
1” and the weekday as “MON” will be displayed. Also, the time will
appear as “-:--” for approximately 1 minute. Then 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).
While the WWVB search is being conducted various numbers will appear in
the time display. The numbers “0”, “1”, or “8” will appear in the hour
position and the seconds will appear in the minute display. The Atomic
Clock will either display the WWVB time, or discontinue the search after 10
minutes if the time is not found. When the search is cancelled “-:--”will
appear in the time LCD. The Atomic Clock 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 (up to 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 12:00 am the next night.
