10. Decide where to locate the ATX. Ideally it should be mounted in
the center of area to be covered. The ATX can either be wall
mounted or sat on a shelf. If the ATX does not receive the WWVB
signal in the next step, then consider installing it near a window
facing Boulder Colorado or under a skylight with a clear view of the
sky to receive the best signal from the WWVB.
11. Press and release the Reset button. The Display will blink once and
the red LED will flash. The WWVB reception indicator
will
scroll left to right indicating it is waiting for a signal.
BE PATIENT!!!
Because of other interfering radio transmissions,
reception often takes 24 hours to occur
If the ATX fails to receive the WWVB after 24 hours, press the RECV
button for 4 seconds to begin WWVB reception again and move the
ATX to another location with a clear line of site toward the sky.
Once the ATX receives the WWVB signal do not change its location.
Because it must continue receiving WWVB signals, the ATX must be
installed in the same area where WWVB signals are first received.
Once the WWVB signal is received, the indicator
will stop
scrolling. (To verify the WWVB signal has been received in the past
24 hours press the RECV button for 2 seconds and release.
The
indicator will flash 4 times indicating the signal has been received or
5 times if no reception has occurred).
