A:Answer When pairing the LG 220W Hi-Fi Entertainment System with Bluetooth® Connectivity, Model # OM4560 to another Bluetooth device, if asked for a PIN code, enter (0000) as instructed on page 19 of your owner's manual for this unit. You can connect this unit with up to 3 Bluetooth devices simultaneously but if while the unit was not paired with your phone, you paired it with another device as the third device, it will not be able to pair with your phone and you will need to delete one of the devices from the paired units. You may also want to try unpairing it with your phone and try pairing it again...^IFV
