Clean your
watch after each use as described here. If you have problems
charging your watch, you can also clean the contact points on your
watch and the USB charging clip.
Caution:
During cleaning, do not press on the glass or
buttons too hard to avoid damaging them and causing the watch to
malfunction. Do not use benzine, thinner, alcohol, harsh detergent,
or any other organic solvent or you may damage your
product.
