Select "GS-1+" from the GS-1 Editor app.
The Bluetooth indicator on the GS-1 stops
blinking and remains lit when pairing is finished.
If connected correctly, it will be in the following
state.

NOTE
¹ You cannot use the GS-1 Editor and the
FS-1-WL Editor at the same time.
¹ Do not tap "FS-1-WL+" in GS-1 Editor app while
connecting.
The FS-1-WL remembers the information
for the last Bluetooth device to which it was
connected.
When connecting to a different device after
connecting to the GS-1, or when turning
off the power while the Bluetooth indicator
is blinking white (not connected), or when
doing a factory reset of the FS-1-WL, the unit
does not pair automatically.
In this case, you must start from step 1 to
configure the settings.
