The measurement functions built into this watch are not intended for
use in taking measurements that require professional or industrial
precision. Values produced by this watch should be considered as
reasonably accurate representations only.
Though a useful navigational tool, a GPS receiver should never be used as
a replacement for conventional map and compass techniques. Remember
that magnetic compasses can work at temperatures well below zero, have
no batteries, and are mechanically simple. They are easy to operate and
understand, and will operate almost anywhere. For these reasons, the
magnetic compass should still be your main navigation tool.
CASIO COMPUTER CO., LTD. assumes no responsibility for any loss or
any claims by third parties that may arise through the use of this watch.
