Philips sonic toothbrush FlexCare 900 - Manual (Page 15)

Question Answer
You may need to replace the UV light bulb (see chapter
‘Replacement’).
Why does the toothbrush seem to
lose power during brushing?
You may be in the Max Care brushing routine. If this is the case,
the routine alternates between the Clean and Massage modes
throughout the 3-minute brushing cycle. The Clean and Massage
modes have a different sound and brush movement.
Do I need a special charger if I
travel with my Sonicare?
Travel tip: the Sonicare charger and the UV sanitizer can be used
with common worldwide voltages between 100-240V AC, at
either 50 or 60Hz. A simple plug adapter is all that is required.
