In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the power is shut off so
that the unit cannot operate.
These following two methods are available to prevent this. Take note of which to use during repairs.
Method 1.
Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the commander switch to the "ADJ" side.
Method 2.
Use the DC IN terminal. (Use the AC power adaptor.)

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-358D 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-358D board.
3) To page A, address 00 to 13, input the data noted down.
