J49

  • 1-2 = select 5VA power

  • 2-3 = select 12V power

power via a 0.2A resettable fuse (polyfuse).

 

the default setting is GND (0v) on pin 13

Note : units built before April 2024 may have had pin 13 set to +5V at the factory

if 0v is required use pins 5,6,18,19 instead

Switch #4 on the main board is to enable or disable headset detect
