Philips Sonicare 7800 - Manual (Page 16)

Solution
Recharge your Sonicare for at least 24 hours.
Verify your Sonicare is plugged into a live electrical outlet and not into
an outlet controlled by a light switch.
You may need to re-attach or replace the brush head.
You may experience a slight tickling/tingling sensation when using
Sonicare for the first time. As you become accustomed to brushing
with Sonicare, this sensation will diminish.
Sonicare should produce a gentle hum during operation.Tightening the
brush head nut can eliminate excessive rattling. If rattling does not stop,
you may need to replace the brush head.
This can be avoided by keeping the brush head properly oriented, with
the brush head placed on the gumline at an angle of 30 to 40 degrees.
The handle may need recharging.
The Easy-start feature may be on and needs to be deactivated (see
'Special features').

your Sonicare').
