                  Systems 360



Similar to the UIQ-10 Public Address Set.


The main unit is designed to be worn in a horizontal position at the small of the back.  That leaves the front of the body free to carry an instrument in a marching band.

The wall-wart for changing the internal battery (Fig 4)  has a 120/230 VAC switch so can be used worldwide.  The output is 26.8 VDC center positive on a5.5 x 2.3mm power plug.

The battery is missing.  When powered the battery terminals show 10.8 VDC (red positive).  So, maybe it uses a "12 Volt" battery?
