The overheat protection function has been activated: When the epilator stops working and the speed setting indications and the charging light start flashing red, the overheat protection has been activated. Let the appliance cool down. The lights stop flashing after 30 seconds. When the appliance has cooled down, switch on the epilator again. If the lights start flashing again, the epilator has not yet cooled down sufficiently.
The rechargeable batteries are empty: When the charging light lights up red continuously, the batteries are empty and you need to charge the appliance. You can also run the appliance from the household power when the batteries are empty.
The travel lock is active: Press and hold the on/off button for 3 seconds until the speed setting indications flash white 2 times. The travel lock has been deactivated and you can press the on/off button to switch on the appliance. You can also insert the appliance plug into the inlet outlet and the adapter into a wall outlet to deactivate the travel lock.
The overload protection is activated because something got caught between the rotating tweezers or because you pressed the appliance too hard onto your skin: When the overload protection has been activated, the speed setting indications flash red. Turn the tweezers with your thumb until you can easily remove the item that is blocking the rotating tweezers. Then switch on the appliance again. Do not press the appliance too hard onto your skin. If this advice didn't help you, please contact your local Philips dealer.
