of the system to the unit. The indicator lights green when the AC power 
cord is connected to the wall outlet and the HS-MB1 is engaged.
Notes
● After completing all the connections, make sure there are no misconnections or 
improper wiring before plugging the Power Supply (HS-AC1) (supplied) into 
the wall outlet. Improper wiring or misconnections may cause damage to the 
unit.
● Use the Power Supply (HS-AC1) (supplied) for this model, as other AC adapters 
may cause a malfunction.
