2. In Case of an HDD Failure
When a HDD/VHS DUAL RECORDER AC cord is plugged into a power outlet, the boot loader is read from the
IC8204 (8M FLASH ROM), which activates the HDD and reads the system files in the HDD before getting ready
for operation. In consequence, the HDD/VHS DUAL RECORDER cannot be turned on if the HDD fails.
In case a failure of the HDD is in doubt, use the following procedure to switch the main power of the set ON using
the VHS section alone, by bypassing the HDD operation check.
(1) With the HDD/VHS DUAL RECORDER in the remote control
standby status, transmit code AE from the remote jig for more
than 2 seconds.
(2) The REC LINK button on the HDD/VHS DUAL RECORDER
blinks, indicating that the power supply can be switched ON.
(3) When the code AE is transmitted again from the remote jig,
the button stops blinking and its function is canceled.
