Replacement reminder
Notification symbol
For maximum shaving performance, replace the shaving
heads every two years. The shaver is equipped with a
replacement reminder which reminds you to replace the
shaving heads. The shaver beeps, the replacement
reminder lights up and the arrows flash to indicate that
you have to replace the shaving heads.
Note: After replacing the shaving heads, you can reset
the replacement reminder by pressing the on/off button
for 7 seconds. If you do not reset the replacement
reminder, the shaver resets automatically after 9 shaves.
Overheating
If the shaver overheats during charging, the notification
symbol flashes. When this happens, the shaver stops
charging automatically. Charging continues once the
temperature of the shaver has decreased to the normal
level after approx. 10 minutes.
Blocked shaving heads
If the shaving heads are blocked, the notification symbol
continuously lights up red. The replacement reminder
and the cleaning reminder alternately flash white and the
shaver beeps. In this case, the motor cannot run because
the shaving heads are dirty or damaged. If the shaving
heads are dirty, you have to clean them. If the shaving
heads are damaged, you have to replace them.
Foreign object on wireless Qi charging pad
If there is a foreign (metal) object on the wireless Qi
charging pad during charging, the notification symbol on
the wireless Qi charging pad lights up. The wireless Qi
charging pad switches off automatically and restarts 5
minutes after the foreign object has been removed.
Do not place any foreign (metal) objects on the
wireless Qi charging pad. Only use the wireless Qi
charging pad to charge the shaver or another device
(e.g. smartphone) compliant with Qi charging.
