4.2 Įjungimas / išjungimas

Press and hold the power button on each unit to turn it on or off. The main unit features a color LCD display, while the receiver has LED indicators.

5. Naudojimo instrukcijos

The NF-8518 offers various testing modes accessible via the main unit's menu. Use the navigation buttons (Up, Down, Left, Right, OK) to select functions.

5.1 Cable Tracking (SCAN/TEST)

This function helps locate target cables within bundles. Connect the cable to be traced to the main unit's SCAN/CONT port. Select the 'TEST' or 'SCAN' function from the menu. Use the receiver to scan the cables; it will emit audible beeps and show visual signals when near the target cable. Adjust sensitivity for precise localization.

5.3 Prievado mirksėjimas (FLASH)

To quickly identify a network port on a switch or router, connect the cable to the transmitter's 'Length/Flash' port. Select the 'Flash' function from the main menu. The indicator light on the corresponding port of the network device will blink, allowing for easy identification. This function supports 10M/100M/1000M speeds.

5.7 Vizualinis gedimų ieškiklis (VFL)

The VFL function helps identify faults in fiber optic cables. Remove the protective cap from the VFL port (located near the OPM port) and connect the fiber optic cable. Select 'VFL' from the menu. A visible red laser light will be emitted. Observe the fiber for light leakage, which indicates breaks or damage. The VFL supports fast flashing, slow flashing, and continuous illumination modes.
