from the Line-in jack on
G-TUBE to your audio device and initiate playback.
NOTES:
For the best audio performance and minimal distortion, avoid turning
the volume on your external audio source all the way up.
If a Line-In cable is connected, G-TUBE will default to Line-in mode.
If the PAIR button is pressed while the 3.5mm Line-in cable is still connected to
the Line-in jack, G-TUBE will switch to Bluetooth pairing mode.
To return to Line-in mode, simply reconnect a cable to the Line-in jack.
If no Line-in cable is connected to the Line-in jack, G-TUBE will default to
Bluetooth mode and begin searching for a Bluetooth pairing device.
