What to do when a user forgets a password
This camcorder has the forced log insertion function. A password is inputted, and this function is set up. When this function was set up, this
camcorder doesn't move if the memory stick which memorize a correct logo isn't inserted. To release the forced logo function, the correct
password must be input.
This password is memorized in the IC1105 (EEPROM) on VC-242D board. Therefore, when a user forgets the password, replace the IC1105.
This IC1105 memorizes the HRS METER data (Hour meter data: page A, address 00 to 13), too. Therefore, replace the IC1105 in the
following order to copy the HRS METER data.
Replacing procedure:
1) Note down the data of page A, address 00 to 13.
2) Replace IC1105 (EEPROM) on VC-242D board.
3) To page A, address 00 to 13, input the data noted down.
(Refer to "HRS METER (Hours meter)" of "5-4. SERVICE MODE")
