How to Power ON / OFF
Since the TC419 does not have a built-in battery, it needs to be connected to a power source in order to power up. We suggest that you connect it to the USB port on the TV / PC / Receiver you're using the TC419 with, so that it turns on / off with your TV / PC.
If your TV does not have an USB port, you can power the TC419 up with your cellphone USB adapter, as long as the adapter supports 5V / 500 mA – 2A.
To power on, simply flip the TX/Bypass/RX switch to either TX or RX or Bypass position, depending on the mode you'd like to use.
In case it didn't automatically power ON... Press & hold the Power button for a couple seconds to turn it on.
