3-2-5. Adjusting Remote Commander

The adjusting remote commander is used for changing the
calculation coefficient in signal processing, EVR data, etc.
The adjusting remote commander performs bi-directional
communication with the unit. The resultant data of this bi-
directional communication is written in the EEPROM.
Precautions upon using the adjusting remote
commander
Mishandling of the adjusting remote commander may erase
the correct adjustment data at times. To prevent this, it is
recommended that all adjustment data be noted down
