Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out
of your purchase, be sure to carefully read this manual and keep it on hand
for later reference when necessary.
Applications
The built-in sensors of this watch measure altitude, barometric pressure,
temperature and underwater depth. Measured values are then shown on the
display. Such features make this watch useful when hiking, mountain
climbing, skin diving, or snorkeling, or when engaging in other such outdoor
activities.
For a watch with the elapsed time bezel
Rotate the elapsed time bezel to align the
mark with the minute hand.
After that, the number of minutes that elapse is
indicated by how far the minute hand has moved
from
