Applications

This watch has built-in sensors that measure direction and temperature.

Measurement results are indicated by the watch's hands and displays. These features make this watch

useful when hiking, mountain climbing, 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 mountain climbing or other activities in which losing your way can create a

dangerous or life-threatening situation, always use a second compass to conﬁ rm direction readings.

Important!

• Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other

activities, always be sure to take along another 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 bidirectional

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.)
