fixation arm

The computer screen is mounted together with the keyboard fixa tion arm on its fixation arm. The other
end of the monitor fixation arm is mounted beneath the tabletop (see Pic. 15a and Pic. 15).

There are two possible ways for mounting the monitor unit onto the table:

1. Premounting of monitor arm, keyboard arm, and monitor before assembly of the whole unit onto
the lift table.
This is recommended if several persons are installing the device together.

2. Premounting of monitor arm and lift table before assembly of keyboard arm and monitor.
This might be more comfortable if there is a single person installing the device. It is easy to
adjust the monitor fixation arm with one hand while looking beneath the tabletop and mounting
the screws. Handling the whole premounted unit with one hand while adjusting the screws
beneath the table needs more strength.

Avoid touching the surface of the screen.

5.8 Cleaning

If necessary, clean the mirror of the slit lamp

.
We recommend to remove dust using compressed air, which is commercially available in aerosol cans.
Fingerprints can be removed with a small amount of ethanol and lens cleaning tissue. Contact
Heidelberg Engineering support for a detailed description for the cleaning of mirror and glass fiber head.

If necessary, clean the computer monitor

.
Again, the best way to remove dust is compressed air. In order to remove fingerprints use special
cleaners for TFT computer screens, e.g. a special tissue with alcohol free cleaning fluid.

For information on maintenance, please refer to the SL-OCT Operation Instructions.

Start the acquisition. Adjust the rod until a horizontal bright white line is visible in the upper third of the
OCT display (see Pic. 69).

If the OCT image of the rod is not shining bright or located at a wrong position in the B-scan, refer to
section 8 Appendix A Troubleshoot.

Pic. 69 Measuring the slit lamp’s test rod

When the test image of the rod is correct, stop the data acquisition and remove the test rod from the slit
lamp. Cover the holding of the rod with the protective cover again.

Now the installation process of the SL-OCT device is finished.

7 Disassembly of a SL-OCT unit

This section contains special notes for the disassembly of the SL-OCT unit. Basically the disassembly is
the installation procedure in backwards order.

If packages for the unit are lost, contact Heidelberg Engineering for replacement. In any case the original
cardboard boxes must be used for transportation of the SL-OCT unit.

Please slightly screw all screws and washers after disassembly in their screw holes again. Loose screws
in the cardboard boxes may damage the SL-OCT unit!

Removing the fiber connection
Attention: Do not buckle the glass fiber!

Do not touch the head of the fiber!

Before opening the fiber connection on top of the scanner-box, be sure that the protection cap for the
fiber plug is ready to hand. As soon as the plug is disconnected, protect the fiber head with the cap (see
Pic. 55a).
If necessary there are replacement caps in the package of the OCT-box.

Packaging the slit lamp into the cardboard box
Attention: Do not touch the mirror!

First, remove the eyepieces from the slit lamp’s microscope.
Mount the protective caps onto the connectors on top of the scanner-box. If necessary, there are
replacement caps in the package of the OCT-box.
Protect the slit lamps mirror with a lens cleaning tissue as shown in Pic. 52.
Protect the slit lamp against vibrations with the transport protection also shown in Pic. 52.

Lower the slit lamp as low as possible by turning around the control lever.

Opening the plastic clip

Use a screwdriver for slotted head screws for opening
the clip as shown in Pic. 70. Block the locking
mechanism with the screwdriver and part the slit of
the clip.

Removing the flexible plastic tube
Attention: Do not buckle the glass fiber! Handle the fiber with care.

The flexible plastic tube consists of two pieces that are clipped together. First remove the outer part.
Then take both cables – glass fiber and scanner cable – in one hand and pull them out of the slit of the
inner tube.

Putting the column into the cardboard box

After the tabletop is removed from the column, connect mains and lower the column as low as possible.
Attention: Be very careful because cables in the open control console are alive!
The column must be telescoped to the lowest position before it can be put into the cardboard box.

Removing the wheels from the foot

First disassemble the column from the foot.
For removing the wheels from the foot, a solid screwdriver for slotted head
screws at least 6 mm is required. Place the foot on a table near the table’s
edge. Insert the screwdriver between nut and top of the wheel as shown in Pic.
71 and lever the wheel from the pin (see arrow).
