Notes on the time signal reception

Receiving the time signal

There are three ways to receive the time signal:

Methods Explanations

Automatic reception

On demand reception

Recovery automatic

reception

The second hand indicates the reception result (OK/NO). (See page 9.)

Receives the signal at 2:00 a.m. every day. If reception is unsuccessful, the watch tries to receive at 3:00 a.m. and 4:00 a.m.

Receive the signal manually when you want to adjust the time and date. See page 22.

Receives the signal automatically after charging when the watch stops due to insufficient charge.

• The time signal reception function cannot be deactivated.

• Even when this watch receives a time signal successfully, the accuracy of the displayed time will be dependent on the reception environment and internal processing.

• If the watch is not able to receive the signal, it will operate normally within an accuracy range of ±15 seconds per month.

When receiving the time signal

Remove the watch and place it on a stable surface where it can receive the signal better, such as next to a window.

• The reception antenna is located at the 9:00 position of the watch. Place the watch with the 9:00 position facing toward the station.

• Do not move the watch during time signal reception.

• The watch will not receive a time signal when in a low charge state as indicated by the second hand moving in two second increments (the insufficient charge warning). Charge the watch before reception.
