Cleaning the unit
Regular dusting with a dry soft, non-abrasive cloth will generally keep the finish of the front panel and
chassis cover looking like new. Avoid the use of domestic cleaning products.
Dust or finger marks can be removed from the front panel using a soft, slightly damp cloth. Disconnect the
power cord before cleaning the unit. Ensure that no water is allowed to enter the case and do not reconnect
the power cord until you are certain that the unit is completely dry.
At no time should you allow any liquid to enter the unit; it may run into the electronic circuitry and cause
damage that will not be covered under the product warranty.
Note: Do not use abrasive cleaners on any part of the unit.
To clean the audio connectors
The audio sockets on the back of the unit are gold-plated and need no cleaning if gold-plated Phono plugs
are used. Otherwise, it is recommended that the end-user unplugs and reconnects the plugs at least once a
year.
Packaging Materials
We recommend that you retain all of the packing material and shipping boxes for the unit. They are custom
designed to reduce the likelihood of damage during shipping. We will accept no responsibility for any
damage occurring to the unit, or accessory, that is shipped in packing material other than the original
packing material.

Handling electrostatic discharge-sensitive devices
Any assembly or component part containing transistors or integrated circuits (ICs) should be considered
sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge
between objects.
Protect against ESD damage by equalising the charge so that the machine, the part, the work mat, and the
person handling the part are all at the same charge.
WHEN HANDLING ESD-SENSITIVE PARTS:
• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people.
• Wear a grounded wrist strap against your skin to eliminate static on your body.
• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even
when you are wearing a wrist strap.
• Use a grounded work mat to provide a static-free work surface.

ENGLISH
Whilst working inside the DH9300 we recommend that the PSU is covered with (?) to prevent contact with
the Power Supply Unit (PSU) which can cause an electric shock.

Replacing the CDROM drive
WARNING:
There is a risk of electrical shock, the power supply can deliver an electrical shock even when the
mains power is removed from the unit; be certain to observe all standard safety precautions.
CAUTION:
The motherboard front panel display socket carries additional power, do not under any circum-
stances attempt to connect a cable plugged in this socket into the hard disk drives or CDROM drive.
This will short circuit the attached device and/or motherboard rendering it inoperable.
TOOLS:
Pozi-driv No.1screwdriver Small flat bladed screwdriver
High Grab Adhesive PSU (Power Supply Unit) or another unit
PARTS USED:
MW00036-01 4x M3 (6mm) Black MW00038-01 4x M3 (6mm) Black

PROCEDURE:
Disassembly
1. Remove the Lid. (See page *DA_REMOVE_LID*)
2. Remove the CDROM drawer front (See page *DA_REMOVE_CDROM_FRONT*)
3. Carefully peel off the EMC tape from the CDROM which is fixed between the drive and chassis
front panel, try not to damage the tape as it can be reapplied again.
4. Using a Pozi-driv No.1 screwdriver, remove 2x M3 screws from each bracket that mount the
drive and brackets to the chassis. You may need to move the front panel and hard disks cables
aside for easier access.
5. Lift the drive up slightly at the rear to release the power cable from the cable retaining bunny
clip. Carefully remove the IDE ribbon (black connectors), Power and Audio cables from the rear

of the drive. Be careful not to touch the power supply unit as it may still hold charge or break
any of the attached cables.
6. Gently lift the CDROM along with the bracket out of the unit.
7. Remove 4x M3 screws securing the CDROM drive to the bracket.
8. The CDROM is glued to the mounting brackets with a high grab adhesive to prevent it from
slipping forwards or backwards whilst in transit. The brackets can be removed by carefully
prising them away from the drive using a thin flat bladed screwdriver.
Preparing a new CDROM drive
1. Brand new CDROM drives are supplied with their facia fitted, in order to use the drive this must
be removed first.
2. To remove the CDROM facia you must open the CDROM’s drawer to take off the drawer front.
This can be achieved by applying power to the unit and by pressing the eject button (See figure
1). The power can be supplied by either temporarily connecting the drive to the unit and turning
the unit on or by connecting the drive to an external PSU (Power Supply Unit). Make sure that
the power is disconnect after the drawer is opened and before proceeding to the next step.
3. The original CDRom drawer front is clipped on to the drawer in much the same way as it’s
replacement (See page *DA_REMOVE_CDROM_FRONT*) if using the plastic version. It can
be easily removed without the use any tools, simply lift the bottom of drawer front to release the
clips and gently slide it up, Please note: The CDROM drawer is likely to break if excessive force
is applied during this procedure.
4. Figure 3 shows the location of plastic tabs that fix the facia to the drive. You will need a flat-
bladed screwdriver to carefully prise the facia off
5. If the unit is going to be fitted with a metal CD drawer front then fit the original drawer front back
on again.

ENGLISH
Assembly
1. Ensure that the CDROM’s facia has been removed, if not then carefully prise off the facia with a
small flat bladed screwdriver (See ‘Preparing a new CDROM drive’ before this section).
2. Set the jumper on the rear of the drive to master, a diagram of the jumper settings can either be
found on a rear or top label.
3. In order to make sure the CDROM drive does not move from it’s position in transit, put two
small beads (3mm in diameter) of high grab adhesive in between the drives mounting holes
(perform on each side). See figure 1.
4. The CDROM bracket is not symmetrical, the flat edge fits to the front left hand side of the
chassis and the angled part is secured to the two mounting pillars opposite within the chassis.
Mount each side of the CDROM drive to the bracket using 2x M3 screws. See figure 2.
5. Gently place the drive into the chassis making sure that the foam EMC gasket (between the
front panel and CDROM drive) does not obscure the CDROM’s play and eject buttons. Not
correctly positioning the drive can also result in the EMC gasket pushing the front of the drive
up, mis-aligning the CDRom drawer front. See figure 3.
6 Align the drive holes with those on the bracket, making sure its flush against the front panel
metalwork then insert and tighten the 4x M4 screws. See figures 3 & 4.
7. Clean any excess adhesive that may have smeared above the bracket with a damp cloth.
8. Connect the IDE cable from Secondary IDE socket (marked PL9) on the motherboard to the
CDROM drive. Do not plug the IDE cable in to the socket marked ‘Front Panel’ as this will
damage the drive. (See page *DA_MOTHERBOARD_LAYOUT* for motherboard layout)
9. Connect the Power cable and Audio lead to the drive and ensure the power cable is neatly
retained by the bunny clips.
10. Replace / Fix the EMC tape from the front panel to the top of the CDROM drive See figure 6.
11. Finally, fit the CDROM drawer front, if required (See page *DA_FITTING_CDROM_FRONT*)
