by your dealer or CASIO distributor at the first sign of low power
(frequent display of RECOV indicator).

static pressure indicated on its case (50, 100, or 200 meters), and

• Your water-resistant watch has been tested in accordance with the
International Organization for Standardization regulations ISO2281
and FTC (USA) "GUIDE FOR THE WATCH INDUSTRY,'' Guide 5.
• Some water-resistant watches come with leather bands. Be sure to
dry a leather band thoroughly whenever it becomes wet. Wearing of
the watch with a wet band may reduce the life of the band and cause it
to discolor. It may also cause skin irritation.
