• If the receiver detects the WWVB signal the SIGNAL indicator will remain ‘On’.
When the receiver receives and decodes the complete information stream from
WWVB the clock display will suddenly begin scrolling for a few seconds and
then the display will show the correct Month, Date, Day, and Time in the Eastern
Time Zone. If you live in the eastern Time Zone there is nothing else to do. Your
unit is now synchronized with the U.S. Atomic Clock and the SIGNAL indicator
will remain ‘On’.
• If you live in a different time zone you should now adjust the display to your own
time zone by holding the TIME ZONE button and pressing the “+” button to
select your own zone as follows:
ZONE 02 — CENTRAL TIME
ZONE 03 — MOUNTAIN TIME
ZONE 04 — PACIFIC TIME
You only need to adjust the Time Zone setting once and the unit will remember
your zone automatically.
Note:
If AC power is interrupted and the back up batteries are exhausted the
clock will again default to “ZONE 01” when the power is restored.
Failure To Receive The WWVB Signal
• If the internal receiver fails to receive the WWVB signal, the receiver shuts ‘off’
and the display changes from “ZONE 01” to “12:10 (AM) Monday 1 01” and
the clock continues running at that point.
• After 50 minutes the receiver automatically switches ‘On’ again and listens for
the WWVB signal for another ten minutes. This cycle will be repeated indefinitely
until the WWVB signal is successfully received and the correct time is displayed.
Note:
Remember that if the Radio is turned ‘on’ the WWVB receiver turns ‘Off’
automatically. So if you turn the radio ‘On’ before the WWVB signal is received
you must manually turn ‘On’ the WWVB receiver again after you turn the Radio
‘Off’. Turn ‘On’ the WWVB receiver by pressing the “+” and “–” buttons together.
The SIGNAL indicator will flash 4 times to confirm that the receiver is ‘On’ again.
