To improve reception
Reception is governed in large part by where the
radio-controlled clock antenna is set up and
which direction it is pointed in.
Location of radio-controlled clock
antenna setup:
If the installation is within a building made of
reinforced concrete, reception will be weaker the
farther the antenna is from a window. To
improve reception, place the antenna as closes as
possible to the window.
Direction the antenna faces:
Reception changes depending on the direction
that the antenna is facing. Look at the display
window to check reception, and turn the antenna

so that it faces in the direction where reception is
most stable.
Reception may be poor when the antenna is placed
on a metal surface such as that of a steel desk.

a large volume of traffic.
Location of transmitting source
Time signals are transmitted from the following
location:
