searching. If there is no WWVB reception, the alarm clock will
search the WWVB time signal every 2 hours until the WWVB
time is received. After reception, this alarm clock will only
search for the atomic signal after midnight (UTC 7:00, 8:00,
9:00, 10:00, and 11:00)
POSITION THE ALARM CLOCK
Position the alarm clock six feet from other electronics for
