each other, there is no need to re-pair at next use.
Every time the BTS001 is turned on, it will connect to the last connected

off the Bluetooth function of the last connected devices first and then try
re-pairing with the new device according to steps 1～6 mentioned above.
Pairing the BTS001 with a Bluetooth transmitter
You can connect the BTS001 to a Bluetooth transmitter to enjoy music
wirelessly. Take the QLink Bluetooth transmitter for example. The pairing
steps are as follows:
1) Keep BTS001 and Bluetooth transmitter within 1 meter when pairing;
2) Enter BTS001's pairing mode (refer to "How to enter pairing mode);
3) Turn on the Bluetooth transmitter. It will search for Bluetooth devices
automatically and send a pairing request;
4) When BTS001 requests to enter a PIN No., the transmitter will response
"0000" automatically;
5) After successful pairing and connecting, the blue LED of the BTS001
flashes once every 2 seconds.
Remarks:
The pairing password of BTS001 is "0000". So, the BTS001 can only
pair with Bluetooth transmitters whose pairing password is "0000", too.
If pairing still fails after several tries, refer to the Bluetooth transmitter's
user's manual for further information.

phone with HFP profile, the other one is the device with the A2DP profile. If
