4. Operating Instructions
The CX249-23 features a double control system, allowing operation via both a sensor and physical switches.
4.1 Controls
- Power Button: Press to turn the light ON/OFF.
- Light Intensity Adjustment: Use the designated buttons to increase or decrease the light intensity steplessly. The light intensity can exceed 30000 Lux.
- Color Temperature Adjustment: Adjust the color temperature within the range of 4000K-6400K to suit procedural needs and reduce eye strain during long operations. The optimized color temperature range is 5500K-6500K, similar to natural light.
- Sensor Control: Wave your hand within the inductive distance (0-90mm) to activate or deactivate the light without physical contact. The interaction range for the sensor is 20-80mm.
4.2 Positioning the Light
The CX249-23 offers free movement across 3 axes, allowing precise positioning of the light to the desired area.
- Vertical Adjustment: Adjust the light head up or down along its vertical axis.
- Horizontal Rotation: Rotate the light head horizontally to cover the treatment area.
- Angular Tilt: Tilt the light head to direct the beam precisely.
The light is factory calibrated at 700mm (average arm length) to produce a precise 80x160mm rectangular light pattern with uniform intensity. Illumination outside this pattern is significantly lower to prevent glare in the patient's eyes.
5. Maintenance and Cleaning
Regular maintenance ensures the longevity and optimal performance of your dental operating light.
- Cleaning Handles: The handles of the CX249-23 are removable for easy cleaning and sterilization. Detach the handles, clean them with a suitable disinfectant, and reattach securely.
- General Cleaning: Wipe down the exterior surfaces of the light head and arm with a soft cloth dampened with a mild, non-abrasive disinfectant. Avoid spraying liquids directly onto the light.
- Lens Cleaning: Gently clean the LED lens with a soft, lint-free cloth to ensure maximum light output.
- Inspection: Periodically inspect all moving parts and connections for any signs of wear or damage.
