Before You Call-Troubleshooting; Calibration Check Procedure - Chattanooga LIGHTFORCE FXi LTC-1510-L-B6 Gebrauchsanleitung

If there are scratches on the massage ball:
There will be minor scratches on the massage ball resulting from normal use. These will
not affect the efficacy of the laser treatment. Figure 27 shows a massage ball treatment
head with a ball that has some minor scratches.
Recommendation: If scratches in the large massage ball become significant
(Figure 28), replace the massage ball treatment head.
5.2. Before You Call—Troubleshooting
If you are having a problem with your laser system, please check the list below of common conditions that can occur that you may be able to
resolve without having to contact Customer Care.
The laser system will display error messages to caution the operator to fault conditions. If any of the following errors occur, the laser system will
remain in Standby mode, or return to Standby mode, produce an audible warning and display the related message describing the fault condition.
The following are examples of these fault conditions:
Optical fiber is not inserted,
•
• Remote interlock is removed,
Finger switch is depressed.
•
To proceed, correct the error and press the exit button.
The system continuously monitors the output current of the diodes to ensure they are within the factory calibration settings. If it is detected that
the electrical current levels exceed the upper or lower limits that would result in power levels outside of the ±20% thresholds, the laser will stop
emission and require system reset.
When the laser pulse rate is CW (Continuous Wave), the laser output power is the same as the power setting on the display within operating
•
tolerances.
• When the laser pulse rate is not CW (e.g. 10 Hz), the average output power is 50% of the power setting on the display, within operating
tolerances.
The laser system will not enter or remain in Emission if the laser system is overheating. If temperatures exceed safety limits:
There will be an audible warning.
•
• There will be an error message: Laser temperature is out of range.
Press the exit button and reset the system. Make sure that the ambient temperature of the laser system is within the operating temperature range
of the device. If the problem still exists, contact Customer Care for further troubleshooting.
If the laser system will not turn on:
• Make sure that the power cord is correctly attached and plugged into a functioning power outlet.

Calibration Check Procedure

The instructions below provide steps for performing a calibration "check" that may be performed with certified, NIST traceable equipment. This
procedure is recommended to be performed once a year but is not required unless there is evidence of significant damage or diminished output.
If during the execution of this procedure, the stated requirements are not met, then factory maintenance and re-calibration may need to be
performed on the device. Factory calibration must be performed by certified Service Personnel.
Caution: Calibration is a service procedure to be done only by certified Service Personnel. Adjustment to any internal components by
anyone other than certified Service Personnel voids any existing manufacturer's warranty on the Laser System.
Warning: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous
radiation exposure. Avoid eye or skin exposure to direct or scattered radiation when open.
Laser Power Calibration Check Instructions
Warning: ALWAYS wear laser safety goggles when performing the laser calibration check procedure and follow all laser safety
guidelines.
Equipment Needed: Certified traceable power meter and detector (Figure 29) with appropriate wavelength
and power measurement capabilities
Step 1. Turn off the laser.
Step 2. Inspect and attach optical fiber and power cord as directed. Make sure the optical fiber is
clean and free of any dust, fluid or other contaminants.
Step 3. Turn on the laser system and enter Standby mode.
Step 4.
Increase the power setting until it reaches the maximum wattage setting.
Step 5. Place the laser in Ready mode.
Step 6. Using the aiming beam, direct the distal end of the fiber into the active area of the power
meter. Keep the fiber tip 2-3 cm away from the surface of the active area of the power detector.
Step 7. Activate the laser and record the value in watts from the power meter display. The laser power
reading should be within ± 20% of the power setting.
a. If the results are outside the 20% range, ensure that: all of the light from the fiber is entering the detector, the fiber is
connected correctly, and the fiber is not damaged. Replace with a new fiber if necessary and repeat.
b. If the results are still outside the 20% range, discontinue this procedure and contact Customer Care for assistance.
