After pairing, you can use B-Speech® TX4 with the Bluetooth receiver. If you wish 
to use B-Speech® TX4 with another receiver, you need to pair them also.
In this case, B-Speech® TX4 will not re-connect with the previous device until you 
pair them again.

The pairing process

1. Before pairing, please check that both devices are fully charged.

2. Check that both devices are within 3 meters of each other.

3. Turn the Bluetooth receiver on and make sure it is in pairing mode. (If in doubt, 

read your receiver user guide).

4. Turn the TX4 on by pressing the On / Off button. The red and blue LED flashes 

alternating for 6 seconds; the TX4 is in pairing mode.

5. Both devices should now find each other and pair. The red and blue LED on the TX4 

flashes slowly at same time when the pairing is successful.

Playing music

1. Insert the connector of the turned on B-Speech® TX4 into the 3,5 mm socket of the 

source device.

2. Make sure the receiver is turned on and within10 meters of the B-Speech® TX4.

3. The red and blue LED from the B-Speech® TX4 indicates that a Bluetooth 

connection exists by flashing slowly at same time.

4. If the connection disappears, the sound is disrupted or breaks down: Move the 

receiver nearer to the TX4. Put the receiver in search mode and it will connect again 

automatically. If the connection does not automatically follow, start the pairing process 

again.

Please note:

1. If for any reason the B-Speech® TX4 does not play any music, it should be restarted.

(See chapter about pairing.)

2. Normally, the connection between the transmitter and the receiver is established 

once the pairing process is done.

The connection can break for the following reasons:

- The distance between the devices is greater than 10 meters or an obstacle stands 

between the devices.

- One or both of the devices have been turned off or must be recharged.

To start the search or pairing function again put the Bluetooth receiver in search mode 

or start the pairing process.
