Replacing the shaving heads
2yrs
For maximum shaving performance, we advise you
to replace the shaving heads every two years.
Replace damaged shaving heads immediately.
Always replace the shaving heads with original
Philips shaving heads ( 'Ordering accessories').
Replacement reminder
The replacement reminder indicates that the
shaving heads need to be replaced. The shaving
unit symbol lights up continuously, the arrows
flash white and you hear a beep when you switch
the shaver on or off.
1 To replace the shaving heads, remove the
shaving heads from the shaving head holder
one by one. See chapter Thorough Cleaning for
the instructions on how to remove the retaining
rings and shaving heads.
Note: The shaving heads are locked by a blue or
an orange retaining ring. Follow the correct
instructions.
2 To reset the replacement reminder, press and
hold the on/off button for approx. 7 seconds.
Wait until you hear two beeps.
