1.3 Device calibration
The detailed steps of power calibration can be viewed through video
https://youtu.be/ubTiRSZhYTA
Connect the device and the power meter, as in the figure below.
Use an external power meter and put the handpiece on a distance of 2-3 cm to the head of the
power meter.
Follow the procedure.（Taking H1 interface as an example, S3 power calibration process is the
same）

Step 1: Input the password 03986086 to enter the engineer interface. As shown below
Step 2: Click POWR Calibration to enter the power calibration interface. As shown below
Note：First, we need to calibrate the threshold, that is, the power value at 0.5W, and then we
will calibrate the debugging power step by step.
Step 3: Click the SET Threshold button to enter the 0.5w threshold setting interface. As shown
below

Threshold calibration steps
① Enter the power calibration interface, click ，emit 0.5W, check the actual output
power.
② Enter the interface, Based on the default value, adjust the value according to the
actual output power.（There is no limit value for downward adjustment, and upward
adjustment cannot exceed twice the default value, each adjustment data recommended
increase or decrease 1-2, if the value difference is too large, increase or decrease 5-8）
Example：
1、If you click 0.5w, the actual light output is 0.4. In the threshold adjustment interface, add 1 to
the initial value, and check the actual power again, and so on;
2、If you click 0.5w, the actual light output is 0. In the threshold adjustment interface, add 5 to the
initial value, and check the actual power again, and so on;
3、If you click 0.5w, the actual light output is 0.6. In the threshold adjustment interface, decrease 1
from the initial value, and check the actual power again, and so on;
4、If you click 0.5w, the actual light output is 1. In the threshold adjustment interface, decrease 8
from the initial value, and check the actual power again, and so on;
Step 4: Return to the power calibration interface, select the power to emit light, fill in the ‘Real’
option with the number on the power meter, and click the CONFIRM button. Repeat this step for
each line

Step 5: After recording the measured power value, click the ‘Restore’ button, wait for the "bee----"
sound, then click ‘All Down’, at this time, the power calibration data issuance process will be
displayed. After the process is over, select the power to emit light again, record the re-measured
value, and check whether the power is within the error range.
If the power re-measured value is within the error range, the calibration is complete. If the power
re-measured value is out of the error range, repeat the fourth and fifth steps until the power output is
within the error range.
Enter the treatment interface, set different wavelengths and powers, and check whether the power
input is within the error range. If it is out of range, perform fine-tuning on the power calibration
interface until the power output is within the error range, then the power calibration is completed.

1.4 Electrical safety test
Use the instrument to perform electrical safety test (class II type B), and consider USB
as accessible part.
Switch on the electrical safety analyzer and set up the data.
Switch on the device.
Confirm the setting of the analyzer and begin the test sequence.
Print the test result.

stubborn spots can be removed with a damp cloth. Please proceed careful not to scratch and
damage the foil on the touchscreen. The device may be disinfected only by wiping it. Spray
disinfection may allow liquids to penetrate into the device.
2.2 Troubleshooting of simple defects
In case of malfunctioning, proceed as follows:
First of all, be sure that operation steps have been carried out correctly.
The touchscreen of the device remains dark after switching it on.
▪ Check the connection of the power cable and/or check the rechargeable battery.
When using an interlock device the laser will not be stopped and blocked after interrupting the
circuit.
▪ Check the connection of the interlock device.
There is no aiming beam or it does not project a uniform circular pattern.
▪ Check to see if the optical fiber is damaged. If the optical fiber is damaged, replace it with a
new one.
▪ Check the connection of the optical fiber is damaged.
Self test fails.
▪ Repeat test.
▪ Check the fiber connection.
