6. I recently purchased the G2 Linbell. There are 38 ring tones. I chose one ring tone that I liked and it works. After one day, the ring tone reverted back to the first tone. I wish to know how I can choose the ring tone that I like and keep it there.
   To adjust and keep the desired ringtones, you should: 1. Firstly choose the ringtone you like; 2. Pairing the device once again. How to Pair: Keep pressing any key on the side of the receiver about 3-5seconds until the light goes on. Then press the transmitter, the bell rings, which means the pairing is finished. Note: You can do this repeatedly every time you want to change the ringtones.
