What should I do if I’m unable to pair speakers together?

Setting up:
*Make sure the power to the main Houston unit is switched ‘OFF’.
*Connect both speakers to mains power supply using the 2 adaptors provided and ensure the On/Off switches on both speakers are set to ‘ON’.
*At this point you will see a flashing RED light on the LEFT speaker and a flashing BLUE light on the RIGHT speaker.
*Wait for a few seconds and you should hear a ‘bing bong’ sound. This indicates that the speakers have now linked together (can take 30 seconds to 1 minute the first time).
*You should now have the light on one speaker as a solid colour and the other speaker light will still be flashing. This indicates that the speakers are linked together and the flashing speaker is now searching for the main Houston unit.
*At this point you need to power ‘ON’ the main Houston unit and wait again for a ‘bing bong’ sound. This indicates that the speakers have now connected to the main unit.
*You can now start to use the unit on whichever function you wish..
