4. Product Overview

4.1. Components

The FY868 cable tester consists of two main units: the Emitter and the Receiver.

• Emitter Unit: This is the primary unit for generating test signals. It features RJ45 and RJ11 ports, LED indicators for cable status, and a rotary dial for mode selection.
• Receiver Unit: This unit is used to detect signals from the Emitter. It has a probe for tracing cables, an ON/OFF switch, a volume control dial, and LED indicators.

4.2. Controls and Ports

Familiarize yourself with the controls and ports on both units:

• Emitter:
  • RJ45 Port: For connecting Ethernet cables.
  • RJ11 Port: For connecting telephone cables.
  • Rotary Dial: Selects operating modes (OFF, SCAN, TONE, CONT, TEST).
  • LED Indicators (1-8, G): Display cable continuity and status.
  • ON/OFF Button: Powers the unit.
• Receiver:
  • Probe: Used to trace cables and detect signals.
  • Volume Dial: Adjusts the audio output for tracing.
  • ON/OFF Switch: Powers the unit.
  • LED Indicators: Signal strength and status.

5. Setup

5.1. Battery Installation

The FY868 requires batteries for operation. Ensure correct polarity when inserting.

• Emitter: Open the battery compartment on the back and insert three (3) 1.5V AAA batteries.
• Receiver: Open the battery compartment on the back and insert one (1) 9V 6F22 battery.

5.2. Connecting Cables

Depending on the test, connect the appropriate cable to the Emitter unit:

• For RJ45 cables, use the RJ45 port.
• For RJ11 cables, use the RJ11 port.
• For other wires or bare conductors, use the provided alligator clip test line.

6. Operating Instructions

6.1. Cable Continuity Test (RJ45/RJ11)

This mode checks for open circuits, short circuits, and cross-connections in network and telephone cables.

1. Connect one end of the RJ45 or RJ11 cable to the corresponding port on the Emitter unit.
2. Connect the other end of the cable to the corresponding port on the Receiver unit.
3. Turn on both the Emitter and Receiver units.
4. Set the Emitter's rotary dial to the "TEST" position.
5. Observe the LED indicators (1-8, G) on both units.
• Normal Connection: LEDs on both units will light up sequentially from 1 to 8 (and G for shielded cables), indicating proper continuity.
• Open Circuit: If a specific LED on the Receiver does not light up, it indicates an open circuit on that wire.
• Short Circuit: If multiple LEDs light up simultaneously or in an incorrect sequence, it may indicate a short circuit.
• Cross-Connection: If the sequence of LEDs on the Receiver differs from the Emitter, it indicates a cross-connection.

6.2. Line Tracing / Finding

This mode helps locate a specific cable among a bundle or trace its path.

1. Connect the cable to be traced to the appropriate port on the Emitter unit (RJ45, RJ11, or alligator clips).
2. Turn on the Emitter unit and set its rotary dial to "SCAN" or "TONE".
3. Turn on the Receiver unit and adjust its volume dial to a comfortable level.
4. Use the Receiver's probe to scan along the suspected path of the cable or among a bundle of cables.
5. A distinct audible tone will be emitted by the Receiver when it detects the signal from the Emitter, indicating the presence of the target cable. The tone will be loudest when directly over the cable.
6. For noisy environments, use the included earphones for clearer detection.

6.3. Line Level and Polarity Detection

The FY868 can detect the line level and polarity of telephone lines.

1. Connect the alligator clip test line to the Emitter unit.
2. Connect the alligator clips to the two wires of the telephone line.
3. Set the Emitter's rotary dial to the appropriate detection mode (refer to the Emitter's markings for specific line level/polarity functions, often integrated with SCAN/TONE modes).
4. Observe the LED indicators on the Emitter to determine the line level (e.g., ringing, busy) and polarity (positive/negative).

7. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Battery Replacement: Replace batteries promptly when the low battery indicator appears or if the device performance degrades. Dispose of old batteries according to local regulations.
