Panasonic ES-LV5U Operating Instructions Manual page 17

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 14.)
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 a full
charge.
Action
When the shaver is
extremely dirty, remove the
foil frame and wash with
water.
(See page 14.)
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
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.
