Start and Shutdown

To turn on the C15, press the power button for around one second. It will take several seconds for the device to boot up and be ready to use. The most recent settings are loaded on startup. To shut down the C15, press the power button again for around a second. The shutdown process takes several seconds, during which it stores the current settings for the next startup, before the device turns off. A small LED next to the power inlet indicates the C15's status as follows:

steady on on/normal operation
slow flashing booting up
fast flashing shutting down
one flash every 2 seconds standby

A flickering LED indicates abnormal operation. For instance, it may mean that the supply voltage is too low.

Make sure not to disconnect the power supply while you are using the C15 (booting up, performance, shutdown), otherwise its data may be lost.
