Have you missed out charging?
When the batteries are completely empty and the
shaver stops, you can give the shaver a quick
charge (sufficient for one cordless shave):
- Charge the shaver until the red pilot light goes out.
Shaving directly from the mains supply
(wall socket)
- If you wish you can connect the shaver to a wall
socket using the mains cord and shave directly
from the mains supply.
