Note:
1) Before troubleshooting or servicing, be sure to obtain customer approval for the following:
a) The recorded contents on DVD/HDD may be lost depending on the details and situation of
fault (defect).
b) The date/time and various settings, including video recording mode, designated by customer
after purchase, may be reset to the defaults before purchase (factory settings).
2) Perform "4-7-2 System reset procedure" after repair is completed: Note that system reset will
erase all error codes that will be necessary for troubleshooting.
3) Take notes of settings on received product in the Memo columns, referring to "Table 4-7-1 List of
items to be reset": These notes will be necessary not only for reset, but for checking any defects
that occur under the particular setting conditions.
