APPLICATION FOR ADJUSTMENT (SEUS)
The application for adjustment (SEUS) is used for changing the
calculation coefficient in signal processing, EVR data, etc. The SEUS
performs bi-directional communication between the personal
computer (PC) and the unit using the USB signal. The resultant
data of this bi-directional communication is written in the non-
volatile memory.
