Mechanism of radio signal reception
The radio-controlled watch displays the precise Time and Date by automatically receiving and synchronizing itself with the radio signal of an official standard frequency.
Time signal transmitted by a standard frequency is based on a super accurate “Cesium Atomic Clock” that may have a 1 second loss or gain per one hundred thousand years.
Automatic reception and manual reception
Automatic reception
This watch sets the time and date by automatically receiving a radio signal at a fixed time.
It automatically receives a radio signal before 2:00 AM, 3:00 AM and 4:00 AM.
When the reception is successful, the watch finishes the automatic reception.
Place the watch in a place where it can easily receive a radio signal (by the window, etc.).
Do not move the watch during the radio signal reception.
Manual reception
This watch can receive a radio signal arbitrarily at any time other than the automatic reception mode.
How to conduct manual reception
Radio signal reception results depend on the receiving environment. Environments in which it is difficult to receive a radio signal
The watch cannot receive a radio signal outside the radio signal reception range. Radio signal reception range indication
When the time zone is set for a region other than the radio signal reception range, radio signals cannot be received. Check the selection of time zone. Time zone display and time difference table
When the watch does not display the correct time and date even after successfully receiving a radio signal, refer to Troubleshooting. Misalignment of the time and hand positions, Misalignment of the date
