Congratulations upon your selection of this CASIO watch.

• Keep the watch away from audio speakers, magnetic necklaces, cell phones,

and other devices that generate strong magnetism. Exposure to strong magnetism can magnetize the watch and cause incorrect direction readings. If incorrect readings continue even after you perform bidirectional calibration, it could mean that your watch has been magnetized. If this happens, contact your original retailer or an authorized CASIO Service Center.
