D. General Reference for Receiving Areas
The following provides a general reference for those areas where the watch is able to
receive standard time radio waves. These areas may vary as a result of changes in radio
rave reception conditions depending on the time period, seasonal variations and weather.
Since this map only provides a general reference of the areas where radio waves can be
received, there may be locations where radio waves cannot be received even if they are
within the range shown on the map.
Standard time radio wave

Location of transmitter

Although the standard time radio waves used by radio wave watches are transmitted
nearly continuously 24 hours a day, transmission may be interrupted for reasons such as
maintenance and inspections. This watch will continue to keep the correct time at an
accuracy of within ±15 seconds per month even if it is unable to receive standard time
radio waves.
