2. Informació de seguretat
Observeu sempre les següents precaucions de seguretat per evitar lesions i danys a l'equip:
- Do not look directly into the fiber end when the splicer is operating, as invisible laser light may be present.
- Assegureu-vos que la zona de treball estigui neta i ben il·luminada.
- Handle optical fibers with care; they are fragile and can cause splinters.
- Mantingueu el dispositiu allunyat de l'aigua i de la humitat excessiva.
- Use only the provided power adapter and battery.
- No intenteu desmuntar ni reparar el dispositiu vosaltres mateixos. Poseu-vos en contacte amb personal de servei qualificat.

4. Configuració i funcionament
Follow these steps for proper setup and operation of the GX39 Fusion Splicer.
4.1. Carregant la bateria
The GX39 is equipped with a 5200mAh lithium battery. Connect the AC adapter to the splicer and a power outlet to charge the battery. A full charge allows for approximately 320 splicing and heating cycles.
4.2. Fiber Preparation
Proper fiber preparation is crucial for successful splicing.
- Pela la fibra: Use the fiber stripper to remove the outer coating of the optical fiber to the required length.
- Neteja la fibra: After stripping, use cleaning wipes moistened with alcohol to thoroughly clean the bare fiber. This removes any residue that could affect splice quality.
- Talla la fibra: Place the cleaned fiber into the optical fiber cleaver. Ensure the fiber is positioned correctly for a precise, perpendicular cut. The cleaver features a tungsten steel blade for a smooth cut surface and has a blade life of up to 48,000 times with a cleaving angle of less than 0.5 degrees.

4.3. Fiber Placement and Splicing
The GX39 features a 3-in-1 fiber holder compatible with various fiber types.
- Place the Fiber: Open the splicer's cover and carefully place the prepared fibers into the 3-in-1 fiber holders on both sides. Ensure the fiber ends are aligned in the V-grooves. The holder supports 3.0mm jumper, 0.9mm pigtail, FTTH fiber, and bare fiber.
- Initiate Splicing: Close the cover. The splicer will automatically detect the fibers and begin the alignment process. The 3.5-inch 800*480 HD LCD screen will display the fiber alignment.
- Splicing Cycle: The GX39 performs fast splicing in approximately 9 seconds. The screen will show the estimated splice loss, typically around 0.01dB for SM fiber.

4.4. Heat Shrinking
After successful splicing, the splice point needs protection.
- Position Heat Shrink Tube: Move the heat shrink tube over the welded fiber joint.
- Place in Heater: Carefully place the fiber with the heat shrink tube into the heating oven.
- Cicle de calefacció: Close the heater cover. The GX39 performs fast heating in approximately 20 seconds.
- Refrigeració: Once heating is complete, remove the fiber and place it in the integrated cooling tray to cool down before handling.

5. Manteniment
Regular maintenance ensures the longevity and performance of your GX39 Fusion Splicer.
5.1. Substitució d'elèctrodes
The electrodes have a life of approximately 4000 splices. When the splicer indicates electrode wear or splice quality degrades, replace them. The GX39 features an innovative tool-free electrode replacement design.

Tool-free electrode replacement for convenience.
5.2. Neteja
Regularly clean the V-grooves, objective lenses, and other optical components with a soft, lint-free cloth and appropriate cleaning solution. Keep the entire device free from dust and debris.
5.3. Durability and Storage
The GX39 is designed with enhanced toughness and features a silicone protective case, making it water-resistant, dust-resistant, and shock-resistant. Store the splicer in its carrying case in a dry, cool environment when not in use to protect it from environmental factors and physical damage.

6. Solució De Problemes
If you encounter issues with your Komshine GX39, refer to the following common troubleshooting tips:
- Poor Splice Quality: Check fiber cleave quality, clean V-grooves and electrodes, and ensure electrodes are not worn out.
- La bateria no es carrega: Verify the AC adapter connection and ensure the power outlet is functional.
- Problemes de visualització: Restart the device. If the problem persists, contact support.
- Fiber Not Detected: Ensure fibers are correctly placed in the V-grooves and the fiber holders are properly closed.
For more complex issues, consult the detailed troubleshooting section on the provided Operation Manual CD or contact Komshine customer support.
