  • Page 15: Panel Controls

    Page 15 of 36 PANEL CONTROLS The panel on the SO-5000 clamp/power supply unit controls the main (coaxial) and auxiliary lights, the powered focus and zoom speeds, and provides an interface for connections to the foot control and battery. Refer to figure 9.

  • Page 16: Lamphouse

    LAMPHOUSE The lamphouse on the SO-5000 ophthalmic microscope produces a coaxial light which provides a red fundus reflex from the back of the eye. The intensity of the light may be controlled from the top panel of the power supply or by using the optional foot controls.

  • Page 17: Positioning The Microscope

    SO-5000 Ophthalmic Microscope User Manual Page 17 of 36 POSITIONING THE MICROSCOPE Note that the equipment must be located more than 25 cm away from any medical gas system or disinfection or degreasing system containing flammable vapour. The power supply must also be protected from liquid splashes and spills.

  • Page 18: Foot Controls

    SO-5000 Ophthalmic Microscope User Manual Page 18 of 36 FOOT CONTROLS The foot control enables the surgeon to focus the microscope, change the magnification level and change the light intensity by depressing pedals, thus enabling both hands to be kept free for surgery.

  • Page 19: Sterilisation

    SO-5000 Ophthalmic Microscope User Manual Page 19 of 36 The microscope may be focused in the upward direction by depressing the pedal (C) and focused downwards using the pedal (F). The drive system will stop automatically when the focus has reached its upper or lower limit.

    SO-5000 Ophthalmic Microscope User Manual Page 20 of 36 CARE AND MAINTENANCE CARE OF THE OPTICAL HEAD Cleaning the optical components. The eyepieces should be checked for cleanliness each time the instrument is used. Surface dust should be removed with a clean, soft brush. Fingerprints or grease may be removed by lightly wiping with a cotton cloth or lens tissue moistened with a 70:30 mixture of absolute alcohol (either ethanol or methanol) and ether.

  • Page 21: Main Lamp Replacement

    SO-5000 Ophthalmic Microscope User Manual Page 21 of 36 MAIN LAMP REPLACEMENT Always use protective gloves while replacing the lamp as lamp temperatures may be sufficiently high to burn skin should it come into contact with the glass capsule. Where possible, allow the lamp to cool before replacing it.

  • Page 22: Auxiliary Lamp Replacement

    SO-5000 Ophthalmic Microscope User Manual Page 22 of 36 AUXILIARY LAMP REPLACEMENT NOTE: The auxiliary light assembly and lamp may be extreme ly hot after extended use. Use a cloth or protective glove to protect hands from the hot surfaces while undertaking lamp maintenance or replacement if the lamp has been on recently.

  • Page 23: Focus Friction

    Page 23 of 36 FOCUS FRICTION The SO-5000 microscope system relies on a friction device to allow the microscope head to stay in position when it is not being focussed, yet still allow the head to be focussed manually or by the motor drive.

  • Page 24: Power Supply

    In many countries the mains voltage fluctuates widely. Low voltage can greatly reduce the light output, and high voltage can greatly reduce lamp life. The Scan Optics power supply automatically provides a constant voltage to the lamp for a wide range of mains power voltages.
