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.
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 7.1CH INPUT and MULTI 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.
