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.
Position Alarm Clock
Position the alarm clock three feet from the electrical outlet
and six feet from other electronics for best WWVB reception.
