The radio tower icon will disappear if the
signal reception is unsuccessful.
About WWVB (Atomic Time) Radio Signal
Reception:
• A continuously displayed radio tower icon
indicates that the WWVB signal was received
successfully during the last attempt. If the
clock attempts to receive the WWVB signal
and is unsuccessful, the tower icon will not be
continuously displayed on the LCD.
• We recommend a minimum distance of 8 feet
(2.5 meters) to all sources of interference,
such as televisions or computer monitors
• Radio reception is weaker in rooms with
concrete walls (e.g.: in cellars) and in offices.
In such environments, place the system close
to the window.
Setup of Time and Display Options:
