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 when the remaining
battery capacity is low. If this
happens, recharge the shaver.
Apply oil. (See page 32.)
The shaving sensor may not
respond when there is not
enough oil on the blades.
Problem
The shaving sensor
responds even though
the shaver is not in
contact with the skin.
Operating time is short
even after charging.
Action
Clean the beard trimmings
from the shaver.
When the shaver is
extremely dirty, remove the
foil frame and wash with
water.
(See page 32.)
Replace the system outer
foil and/or inner blades.
Expected life of system
outer foil and inner blades:
System outer foil:
Approximately 1 year
Inner blades:
Approximately 2 years
Apply oil.
This can be improved by
cleaning every time after
shaving.
When the number of
operations per charge starts
to decrease, the battery is
nearing the end of its life.
