To power on the device, press and hold the power button until the screen illuminates. To power off, press and hold the power button again until the screen turns off.

4. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

4.1 Cable Scan (Digital / Analog Mode)

This function is used to quickly trace UTP/STP cables in various environments. It supports both digital and analog scanning modes.

1. Connect the cable to be tested to the "SCAN" port of the transmitter unit.
2. On the main menu, navigate to "SCAN" and press "OK".
3. Choose your preferred scan mode (Digital or Analog) and press "OK".
4. Use the receiver unit to trace the target cable. The receiver will emit an audible signal when near the cable.

4.2 QC Testing (Crystal Head Testing)

This function tests the quality and continuity of the crystal head (RJ45 connector) of a network cable. It can test even if only one end of the cable is connected.

1. Connect the RJ45 cable to the appropriate port on the transmitter.
2. Select "QC Test" from the main menu and press "OK".
3. The device will automatically test the cable. A checkmark (✓) indicates a good connection, while an 'X' indicates an abnormal connection for each wire.

4.3 പോർട്ട് ഫ്ലാഷ്

The Port Flash function helps to quickly and accurately identify the target cable's port on a network hub or switch by making its indicator light flash.

1. Connect the transmitter to a network port on the switch/hub.
2. Select "Flash" from the main menu and press "OK".
3. Observe the indicator lights on the network switch/hub. The port connected to the NF-8508 will flash at a distinct frequency (around 3 seconds) compared to other ports, allowing for easy identification.

4.4 ഒപ്റ്റിക്കൽ പവർ മീറ്റർ (OPM)

The OPM function measures the optical power of fiber optic cables, supporting automatic identification of fiber frequency and high-precision testing across 6 standard wavelengths.

1. Connect the fiber optic cable to the OPM port on the device.
2. Select "OPM" from the main menu and press "OK".
3. The device will display the measured optical power in dBm and automatically detect the wavelength.

4.5 VFL Function (Visual Fault Locator)

The VFL function uses a 10mW red laser to visually locate breaks, bends, or damage in fiber optic cables. It offers fast flashing, slow flashing, and continuous light modes.
