‐ Do NOT wash the watch with household cleanser. Please use soapless detergent, rinse
thoroughly and wipe with a soft towel ornapkin.
‐ While the watch is water resistant, wearing a wet band is not good for your skin.
‐
If your bands get wet—for example after sweating or showering—clean and dry them
thoroughly before putting them back on your wrist.
‐
Be sure your skin is dry before you put your bands back on.
‐ Do not bring your device into contact with any sharp objects, as this could cause scratches
and other damage.
‐ For light-colored arm bands, minimize direct contact with dark-colored clothing, as color
transfer can occur.
