Problem
Makes a loud sound.
►Shaver
Problem
The power switch
does not turn ON.
Action
During cleaning:
The self‑cleaning
recharger makes a loud
sound due to the cleaning
of the blades.
After cleaning:
The self‑cleaning
recharger makes a loud
sound due to the removal
of water droplets in order
to speed drying.
The sound after cleaning is
different from the sound
during cleaning. The water
level has dropped and it is
removing water droplets
from the blades after
cleaning. This does not
indicate a problem.
Action
Unlock the switch lock. (See
page 16.)
Problem
The shaving sensor
does not respond.
Action
Depending on the beard
thickness or the amount of
beard trimmings in the
shaver head, the shaving
sensor may not react and the
driving sound may not
change. This is not abnormal.
The shaving sensor may not
respond depending on the
type and quantity of the
shaving gel. This is not
abnormal.
The shaving sensor may not
respond when the remaining
battery capacity is low. If
this happens, recharge the
shaver.
Apply oil. (See page 18.)
The shaving sensor may not
respond when there is not
enough oil on the blades.
