4.2 Voice output pin precautions
The Cinderella voice output (connector CON5) is a differential output due to speaker amplifier IC
specifications. Care must be taken to avoid short-circuiting the voice output signal to other signals
(especially GND) when connecting devices, as this may damage the speaker amplifier IC.
In particular, avoid connecting devices with power supplies, such as PCs.
