Usage Features
The unit is operated via a keypad and features an optional phoropter arm and lens drawer.
Keypad:
The keypad allows for:
- Power On/Off: The on/off button lights up blue when in standby and green when in use.
- Chair Height Adjustment: Buttons to raise and lower the chair.
- LED Light Control: Switch on the LED light strip and adjust its brightness (reduce/increase).
Ophthalmology Chair (OC-8):
The chair features a vertical lifting group for height adjustment, controlled by the keypad. It also includes a hand brake for locking and unlocking its rotation. The chair offers 30° rotation for patient access, two armrests, and a reclining footrest.
Tabletop:
The tabletop has two types of movement:
- Rotation: The tabletop can turn 90°, ranging from the rest position to the work position. If instruments are installed, care must be taken not to turn it beyond its maximum length.
- Horizontal Sliding: The tabletop can slide horizontally to position the instruments (first or second instrument). Mechanical fixing ensures the position of the tabletop. A safety sensor prevents the chair lifting group from moving upwards if there is contact with the legs, allowing it to lower to free the legs.
Phoropter Arm (Optional):
The phoropter arm has various adjustments for precise positioning to the patient's face:
- Regulation Force: Adjusted by loosening a safety screw and turning an Allen wrench.
- Maximum Vertical Rotation: Limited by turning a screw; tightening reduces rotation.
- Vertical Position: Locked or unlocked using a handle.
- Lock Vertical Sliding: A slider locks the vertical position.
- Horizontal Position: A slider moves the phoropter horizontally.
- Horizontal Direction: A slider locks the horizontal position.
Lens Drawer (Optional):
This trolley is designed to hold test lenses in its drawer and provides a support tray for other items.
Maintenance Features
For correct maintenance, contact TOPCON's official dealer for work requiring trained technicians. However, some user-level maintenance actions are outlined:
Safety Precautions for Maintenance:
- Always disconnect the device from the mains before carrying out any operations.
- Do not flood or wet the device with water, as it contains electronic components.
- Never use household detergents or foam for cleaning.
Cleaning:
- Clean devices with a damp cloth and mild detergent.
- Avoid abrasive cleaners, powders, scouring pads, steel wool, or sandpaper, as these can damage the tabletop finish and reduce its chemical and stain resistance.
- The laminate of the tabletop is chemically resistant to bleach, ammonium chlorides, and other antimicrobials.
- Do not apply cleaning products directly to the device.
- For disinfection, use specific products from the market or an aqueous solution with an alcohol base and components of quaternary ammonium, observing the action and drying time.
- For disinfection of hard-to-reach areas, small objects, or small areas in the proximity of the patient that have been contaminated and are not likely to be disinfected by heat or immersion in a solution, apply the disinfectant as a spray.
- It is recommended to use neutral products to avoid damage to sensitive parts.
- Apply cleaning products on a clean cloth and then clean the device with the cloth.
Corrective Maintenance (User Level):
Thermal repair of superficial scratches on the tabletop:
This procedure is only valid for the tabletop.
- Put a paper towel on the scratched surface.
- Spray the paper towel with water.
- Iron the paper towel at maximum temperature.
- Caution: The iron should be at its maximum temperature.
- Warning: Do not iron for more than 5 seconds. In addition, during ironing, the iron must be kept in constant motion on the paper towel.
- Remove the paper towel and dry the surface.
- Repeat the operation as many times as necessary.
- Caution: It is not possible to repair with this procedure scratches that have penetrated the protective surface of the tabletop.
Lifting motor of the chair not operational:
If the lifting motor is not operational due to thermal protection from overload or continuous use without respecting the work cycle (2 minutes of work within a range of 18 minutes), perform the following checks:
- Wait for the reset: if the fault is due to an overload of the lifting group, wait until the temperature drops.
- Check the corresponding fuses.
- Warning: Before replacing fuses, disconnect the unit from the power supply.
- Check that the supply voltage matches the specifications of the unit.
- Check the correct connection of the power supply wiring.
If these checks do not resolve the fault, contact the technical support team.
