Procedure:

Preparation

Before installing the internal HDD, a few modifications need to be
made, this to secure the NAGRA -V before the machine is closed once
the option is installed.

Bend to 2 ribbon cables of the Time Code option (if installed) as close
as possible to the bottom of the Nagra-V. This to prevent that they
would be smashed by the internal HDD option.

For the same reason, bend the ribbon cable between the box motherboard
and the LF output PCB as close as possible to the LF output PCB.

Move the camera return cable so that it sits downward to the bottom
of the machine and as most as possible behind the LF output PCB.

Reduce the pin size to maximum 1 mm versus the LF output PCB. Add
some solder to remove any sharp edges.

If on the upper deck
motherboard, the connector J2 is installed, cut all the pins as short as
possible or unsolder the connector. Disconnect the speaker connector.
By removing 10 nuts and 1 screw, remove the upper deck motherboard by
also removing the EDI ribbon cable from the PC104 PCB and the external
HDD as well as the HDD power connector.

On the deck, remove the left 10 mm spacer this
to install afterwards easily the ribbon cable.

Installation

By using double-sided glue tape, add the insulator (0131 030 009) on the
PC104 PCB
