*1 Ten items tested under military specification MIL-STD-810G (nine items tested for the WSD-F30, for which
solar radiation testing was not performed): •Shock: Tested to meet MIL-STD-810G Method 516.7 Procedure IV.
•Vibration: Tested to meet MIL-STD-810G Method 514.7 Procedure I. •Humidity: Tested to meet MIL-STD-810G
Method 507.6 Procedure II. •Solar radiation: Tested to meet MIL-STD-810G Method 505.6 Procedure II.
•Low-pressure transport: Tested to meet MIL-STD-810G Method 500.6 Procedure I. •Low-pressure operation:
Tested to meet MIL-STD-810G Method 500.6 Procedure II. •High-temperature transport: Tested to meet
MIL-STD-810G Method 501.6 Procedure I. •Low-temperature transport: Tested to meet MIL-STD-810G
Method 502.6 Procedure I. •Temperature shock: Tested to meet MIL-STD-810G Method 503.6 Procedure I-C.
•Ice accretion: Tested to meet MIL-STD-810G Method 521.4 Procedure I. (The device has been tested to perform
under test conditions, but is not guaranteed to operate under all conditions in actual use. Not guaranteed against
damage or accidents.) *2 Casio test conditions. *3 The values provided here are based on measurement
conditions defined by Casio. Actual values might vary depending on factors such as the environment in which the
customer uses the watch, the app being used, the smartphone to which the watch is connected, and the system
configuration. *4 Color display auto OFF: When “Always have screen ON” is disabled in the screen settings. When
the watch is not in use, the display switches to monochrome to extend battery life. (Enabled by default for the
WSD-F30.) *5 Regular color display: When “Always have screen ON” is enabled in the screen settings. When the
watch is not in use, a color display with lower brightness and activity is used. (Enabled by default for the
WSD-F20.) *6 For measurements obtained from the ACTIVITY apps for cycling and trekking. *7 For
measurements obtained every minute over 8 hours in one day by using the Extend mode app. *8 When using the
watch only in Timepiece mode or when using the watch and sensors only in Multi-Timepiece mode, Wear OS by
Google is disabled. *9 Actual altitude and elevation above sea level will not match due to the use of GPS-based
altitude information. *10 Default: OFF. *11 Devices that support Bluetooth
®
and on which the Wear OS by Google
app downloaded from Google Play can be installed. *12 Functions available for use when connected through
iOS are restricted.
Safety Precaution
Be sure to read the instruction manual
before using this device to ensure safe,
proper use.
Warning
Do not use any power supply/voltage,
charging cable or AC adapter other than
