Controlling music playback
When the AM04 is powered on and connected to a mobile phone, press and hold the volume up and down keys
simultaneously for 2 to 4 seconds to access the music playback screen.
During music playback, press and hold the volume up or down key for 2 to 4 seconds to switch between songs,
or press and hold the volume up and down keys simultaneously for 1 second or more to pause or continue the
playback.
Deep sleep mode
The Bluetooth range for the AM04 is 10 meters (32.8 feet). If this range is exceeded or there are too many
obstacles between the AM04 and a Bluetooth capable device, the AM04 may disconnect from the device.
Within 60 minutes of disconnection, if the AM04 comes within the Bluetooth range or obstacles are removed,
the AM04 automatically connects to the two devices to which it most recently connected. If the AM04 remains
disconnected for more than 60 minutes, it automatically enters deep sleep mode (a powered-off state). To use
the AM04 again, press and hold the function key for 2 to 4 seconds to power it on.
