Operating the cable tester
Testing cables:
1. Plug the connectors of the cable into the corresponding jacks on either side of the cable tester.
2. Set the Power Switch on the sender to the ON position. The power LED will glow red. The first three
LEDs will light in sequence indicating that batteries are installed in both battery compartments.
Note: The flashing LEDs at this point do not indicate cable continuity. They only indicate that
batteries are installed into both sender and receiver.
3. Switch the Cable Test/Tone Test selector on the receiver to the Cable Test position. The power
LED will glow green.
4. If both ends of the cable are properly connected, the pin continuity LEDs will begin to flash and a
beep will repeat to confirm the continuity of PIN 1.
Important: If the LEDs and beep do not start immediately once the receiver has been turned
on, it indicates that PIN 1 of the cable is faulty. PIN 1 needs to be connected in order for the
CBT-MF to begin working.
