Problem
Action
Operating time is
short even after a full
charge.
Although the shaver can be
used for about 2 weeks after
a full charge (assuming
dry‑shave usages for 3
minutes per day), the usable
number of days might be
lower depending on how the
shaver is used (for example,
when used for wet shaving).
Apply oil.
Clean the shaver.
When the number of
operations per charge starts
to decrease, the battery is
nearing the end of its life.
Shaver does not
operate even after
charging.
Use the appliance in an
ambient temperature
approximately 5 °C or higher.
The battery has reached the
end of its life.
The shaver will not operate
with the AC adaptor
connected. Please use the
shaver after it has been
sufficiently charged and the
AC adaptor disconnected.
