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 and the clocks will not synchronize
properly. It is required for proper operation that you install the
ATX in a location that can receive the WWVB signal.
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.
Q. When does the ATX listen for the WWVB radio signal?
A. The ATX listens for the WWVB radio signal 2 minutes and 40
seconds after every hour. The strength of the last signal
reception can be determined by the signal strength indicator
( ) on the display.
