Before attempting to use any buttons on the control plate, ensure that the
power switch on the back of your FS-252 is flipped to the "On" position. Next,
hold the Gear button for two seconds to power on the unit. Once the power
LED is illuminated, click the Gear button to cycle through modes.
Works as an ordinary BT
speaker. Use the Bluetooth
button to pair with your phone.
Same as BT, but this mode
rebroadcasts that BT audio to up
to 4 more speakers via SKAA!
It’s a fully-functional SKAA
receiver. Feed it audio with any
SKAA hardware transmitter, or
any other FS-252 in Relay
mode.
Plug in any 3.5 mm stereo
audio source into the AUX jack,
or any RCA line level source into
the Line In input on the back.
Same as AUX, but this mode
rebroadcasts that AUX audio to
up to 4 more speakers via SKAA!

Connecting a Bluetooth Source
Cycle to Bluetooth mode by clicking the Gear button. When in Bluetooth
mode, the Bluetooth LED will be illuminated.
Enter pairing mode on the Bluetooth device you want to connect to
the FS-252 and select the FS-252 from the discoverable devices list.
This diagram represents the Bluetooth behavior of the FS-252
8/18

Connecting a Bluetooth Source
Initialization
Initialization begins when the user enters BT Mode or BT Relay Mode from
any other mode, by clicking the Gear button. Initialization also begins if
the user powers on the FS-252 in either BT Mode or BT Relay mode.
Pairing List
The Paired List contains up to eight of the most recent hosts which have
successfully paired and connected with the FS-252.
Button
Clicking the button toggles between the Attempt Connection state and
the Pairing state. From the Connected state, a two-second press and hold
of the button will force the FS-252 to drop the connection to its currently
connected device and enter the Pairing state. A ten-second press & hold of
the button will clear the Paired List and enter the Paring state.
Timeouts
From Initialization, the FS-252 attempts to connect to the most recently
connected host for ten seconds. After ten seconds, if a successful
connection has not been established, the FS-252 will enter the Pairing
state.
If the connected host goes out of range, the FS-252 attempts to reconnect
to that host for 60 seconds. After 60 seconds, if a successful connection
has not been established, the FS-252 will enter the Pairing state.
