1. Go to: Setting -> Output Settings-> Speaker Configuration and press «Scan», confirm that there is no TANA L-1 in scan result.
2. Find out a status of TANA L-1: to read status indicators properly, check TANA L-1 Quick Start Guide.
If there is a solid orange LED indicator on the top of TANA L-1, reboot TANA SL-1 and try scanning again If an orange LED indicator is blinking on the top of TANA L-1, then probably the speakers are connected to each other, but TANA L-1 can't reach TANA SL-1. Try to change location to make a TANA SL-1 reachable.
If there is no orange indicator and you still can't find TANA L-1 in «Speaker Configuration», tap fast on the standby button to get the light in the buttons on TANA L-1. As soon as you can see light, press and hold all 3 buttons for 5 seconds until you see solid orange LED. Then try to scan speakers in «Speaker Configuration» again.
