Note : Step4, 5 is to check if CPU software is capable of DSP code. "Software Type No" is to show what "DSP Code Group" CPU is capable of. And vice versa. Step 8 is to manage the 16 codes for DSP. � When the unit is once turned into Service Mode, the unit keeps this mode until the main power is turned off. (Turning into stand-by mode does not make it quit from Service Mode.) When the unit quits from Service Mode, Information in the memory is also cleared and the unit returns to the status when it is out from the factory.

Personal notes:

Product Reset
To reset the back up memory of the unit into the default status, follow the procedure below. 1. Turn of the unit and press SELECT and S-DIRECT button simultaneously more than 1.5 seconds. 2. After "DEFAULT" is displayed on FLD, power is turned off once and turned of again, EEPROM is cleared to the default status, µ-com is reset and the unit returns to the normal status. (Software Serial Number will not be cleared.) Note : When the unit is shipped from the factory, the procedure above must be done to set the unit to initial status after the tests.
