Measurement condition
GND and the speaker output (- side) becomes
a short state on the oscilloscope.
Wrong connection example
Caution in the measurement
Audio Power Amp. (IC5002: LA4628) on the AUDIO AMP Assy is BTL system, and, 
as for the power amplifier and the speaker output, 
±
 poles becomes hot for the 
ground. Therefore be careful not to connect the measuring instrument as the following 
figures. (Power amplifier may be damaged.)
