Band
●
Tightening the band too tightly can cause you to sweat and make it difficult
for air to pass under the band, which can lead to skin irritation. Do not fasten
the band too tightly. There should be enough room between the band and
your wrist so you can insert your finger.
●
Deterioration, rust, and other conditions can cause the band to break or
come off of your watch, which in turn can cause band pins to fly out of
position or to fall out. This creates the risk of your watch falling from your
wrist and becoming lost, and also creates the risk of personal injury. Always
take good care of your band and keep it clean.
●
Immediately stop using a band if you ever notice any of the following: loss
of band flexibility, band cracks, band discoloration, band looseness, band
connecting pin flying or falling out, or any other abnormality. Take your
watch to an authorized CASIO service center or to your original retailer for
inspection and repair (for which you will be charged) or to have the band
replaced (for which you will be charged).
Temperature
●
Never leave your watch on the dashboard of a car, near a heater, or in any
other location that is subject to very high temperatures. Do not leave your
watch where it will be exposed to very low temperatures. Doing so can
cause malfunction.
●
Leaving your watch in an area hotter than +60°C (140°F) for long periods
can lead to problems with its display panel. The display panel may become
difficult to read at temperatures lower than 0°C (32°F) and greater than
+40°C (104°F). Watch operation that is stopped due to high temperatures
will not resume until watch cools sufficiently. Wait for a while to allow the
watch to cool.
Use in Cold Environments
●
Under cold conditions, the operating time provided by a battery is shorter
than normal, even if the battery is fully charged.
●
Extreme cold can cause Wi-Fi operation to shut down automatically to
protect the watch’s system.
