  6. Titmusi400 Vision ScreenerStep 1: Unpacking

  7. Unpacking • If received in case, remove instrument from case using handle • Unlock the handle (use BOTH hands)

  8. Unpacking • Unlock bottom lock using one hand to pull tab and other hand to raise instrument • Lift and remove membrane panel. Not tabs to mount back

  9. Unpacking • Remove internal packing foam • Turn knobs so that white dot matches purple dot (USE BOTH HANDS TO TURN KNOBS)

  14. Titmusi400 Vision ScreenerStep 3: Testing

  15. Operating Far/Near Lever • Operator can sit on any side of instrument • Pull to move far/near lever towards you, push away to move away from you • FAR (mountain), NEAR (book)

  16. Far Vision Testing • Lever in FAR position • Ensure drum assembly is in FAR position. White dot on knob should match purple dot

  17. Near Vision, Natural Line of Sight • Lever in NEAR position, test at optimal line of sight • Turn BOTH knobs so the progressive lens wearer can see most clearly (natural line of sight – looking downwards)

  18. Using intermediate lens • Ensure lever is in FAR position • Place intermediate lens with label facing the front • DO NOT turn knob when int. lens is in the instrument

  19. Patient Seating • Ensure patient is comfortably seated – straight back, forehead placed on headrest • INCORRECT position – back not straight, neck tilted backwards

  20. Patient Seating • Patient correctly seated will activate the head sensor • When head sensor is activated, slides can be seen (clicking sound of the shutters opening) • If a patient tends to move his/her head a lot, shutters will open/close. In this case, override the sensor

  21. Height adjustment • Instrument is designed for patient comfort in order to test efficiently and accurately • Can fit children or adults, standing or seated • To raise/lower the instrument – use BOTH hands on the knobs

  22. Preparation for testing • Place instrument on table of sufficient height • Unlock handle, bottom lock and raise instrument • First connect panel to instrument as shown using panel cord. Then connect power cord to instrument and turn switch ON. • Test all membrane switches on membrane panel to ensure proper operation • Ensure lenses are clean, use cleaning towlettes or fog cloths

  23. Preparation for testing • Place record forms near instrument • Avoid positioning the instrument near strong glaring light to prevent glare while testing • Ensure patient is comfortably seated • Raise the instrument for comfortable viewing, based on patient height • Ensure lever is in FAR position • Ensure drum assembly is in FAR position. White dot on knob should match purple dot.

  25. Care and Maintenance • Clean viewing lenses as needed, use towlettes supplied in accessory case • Clean headrest between tests using a disinfectant solution.

  26. Care and Maintenance • Exterior of instrument may be cleaned with a soft cloth dampened in mild solution of soap and water • Test slides are in a completely enclosed module, hence cleaning is rarely required • Use dust cover to protect instrument when not in use • Slide illumination lamp has a life of over 10,000 hours. Membrane panel will indicate if it needs replaced.
