Attention
※ If the driver's heartbeat signal is too faint for the
DFD-100 to detect, the DFD-100 will switch off 1 minute
after it loses the heartbeat signal.
※ Bad signal quality means the detected signal is
abnormal within 30 seconds continuously, such as: shake
body long time or wrong detected position.
