Set Up 1: Connect the Medley Pebble to your TV / Audio Source

The transmitter dock must be connected to a power source via the provided
power cable in order to function. Plug the transmitter dock into a nearby wall
outlet with the provided 5V/500mA-2A rated USB adapter.
Once the transmitter dock is connected to its power source, you can connect
it to your TV. You can choose one of 2 different ways to do this:

OPTION 1 Optical port (recommended)

Plug the provided optical audio cable into the TV’s optical OUT or “OPT OUT”
port, then plug the other end into the transmitter dock’s optical port in the
“INPUT FROM TV” section.

NOTE: Most TVs support audio output through only one digital output
port at a time, so if your TV’s HDMI ARC port is in use, the optical port may
be disabled. You can either unplug the HDMI ARC, or try connecting the
transmitter via RCA / AUX.

OPTION 2 AUX 3.5mm port

Plug the provided AUX 3.5mm audio cable into the TV’s AUX 3.5mm output
port, then plug the other end into the transmitter dock’s AUX 3.5mm port in
the “INPUT FROM TV” section.
