3, when the razor head symbol, the faucet symbol and the exclamation mark blink at the same time, it means that the razor head is blocked. In this case, the motor will not run because the razor head is too dirty or damaged. If this happens, the shaver head must be cleaned or replaced. When the travel lock is activated, the lock symbol appears on the display. When the battery is about to run out of power (there is only 5 minutes or less left to shave), the charging indicator at the bottom will flash orange.
