ENGLISH

Congratulations upon your selection of this CASIO watch.

ξ Note that the product illustrations in this manual are intended for reference only, and so the actual product may appear somewhat different than depicted by an illustration.

This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.

Using the Crown

This watch has a lock-type crown.

High-speed Movement

To stop high-speed movement

 

When rotating the crown to move the hands of the watch, you can use the operations described below to move the hands at high speed, either forward or back. There are two high-speed levels: HS1 and HS2 (faster than HS1).

To start HS1 high-speed movement

While the crown is pulled out, rotate it rapidly three turns away from you (for forward movement) or towards you (for reverse movement). High-speed movement will continue even if you release the crown.

To start HS2 high-speed movement

While HS1 high-speed movement is in progress, again rotate the crown rapidly three turns in the same direction as the current HS1 movement (away from you for forward movement or towards you for reverse movement).

Rotate the crown in the direction that is opposite that of the current high-speed movement or press any button.

Note

ξIf you do not perform any operation for more than two minutes after pulling out the crown, crown operations will become disabled automatically. If this happens, push the crown back in and then pull it out again to re-enable crown operations.

ξYou can use high-speed hand movement when configuring time settings in the Timekeeping Mode, Alarm Mode, or Countdown Timer Mode.

ξButton operations become disabled after you perform a crown operation. If this happens, rotate the crown slightly. This should restore button operations.
