If the heated sock is used in firmly closed or specially
■
fitted footwear with a very narrow shape, please
make sure that the sock is not wrinkled in the area
of the heating element. This could result in painful
pressure points.
Never use the heated sock in combination with other
■
heated products (heated insole, heated boot, etc.);
there is a risk of excessive heat.
The lithium packs must not be used in or under
■
water!
If used improperly, liquid may leak out of the battery;
■
avoid contact. In the event of accidental contact,
rinse with water. In the event of contact with eyes,
also seek medical assistance. Liquid leaking out of
the battery may cause irritation or burns.
Do not used batteries or devices if they have been
■
damaged or modified. Damaged or modified batteries
can behave unpredictably, which may lead to fires
breaking out or a risk of injury.
Only use qualified repair personnel for maintenance,
