Q. What do I do if the time does not correct on the ATX after WWVB
reception indicator scrolls?
A. Make sure you selected “Master” mode, then move the ATX closer
to a window facing Boulder, Colorado or under a skylight with an
unobstructed view of the sky. Allow 24 hours for reception.
Reception is best at night when there are fewer radio interferences.
Install the ATX in the same place where it finally received WWVB.
Q. Can I set the time on the ATX manually?
A. If you manually set the time on the ATX, Daylight Savings changes
will not occur unless you also set the Manual Spring and Fall Month
and Week describes on pages 5-7. It is recommended that you
install the ATX in a location that can receive the WWVB signal.
Q. If I manually set the Daylight Savings settings will the WWVB signal
affect the ATX?
A. No, the manual Daylight Savings settings override the automatic
WWVB signal for Daylight Savings.
Q. What do I do if my ATX does not update for Daylight Savings Time?
A. Make sure the ATX has a clear view of the sky or faces toward
Boulder, Colorado to insure it receives the WWVB signal.
Q. When does the ATX transmit the time to the secondary wall clocks?
A. The ATX transmits once per hour during the 58th minute between
the 50th and 59th second. When the TRANS button is pressed, the
ATX transmits every 10 seconds for one hour.
