When starting up, do not allow step 3 to be
switched on longer than a few minutes in each
case, otherwise too much heat can be produced
during operation – danger of burning.
Always set Powerpacks to level 1 or 2 to maintain
a comfortable level of warmth for your feet
(heating should be almost undetectable).
The optimum heat output is achieved when your
shoes and soles are dry.
USE AND FUNCTI ONS
The desired heat level can be set individually for
each Powerpack using the level switch (levels 1, 2,
3).
