Important!
•
The watch’s water depth measurement function is intended to be used as a backup depth gauge.
•
Whenever you use the digital compass of this watch for serious diving or other activities, be sure to
always take along another underwater compass to confi rm readings. If the readings produced by the
digital compass of this watch are different from those of the other compass, perform directional
calibration of the digital compass to ensure more accurate readings.
•
Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of a
permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or
electrical household appliances (TV, computer, cellphone, etc.)
Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure direction, barometric pressure, temperature, and water depth.
Measured values are then shown on the display. Such features make this watch useful when diving or
when engaging in other such outdoor activities.
Warning !
•
The measurement functions built into this watch are not intended for taking measurements that
require professional or industrial precision. Values produced by this watch should be considered
as reasonable representations only.
•
When engaging in diving or other activities in which losing your way can create a dangerous or
life-threatening situation, always use a second underwater compass to confi rm direction readings.
•
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss
suffered by you or any third party arising through the use of your watch or its malfunction.
