Jonard Replacement Speaker for PT-300 Pocket Continuity Tester & Toner

You can easily test for continuity and short or open circuits with the PT-300 (sold separately) – the perfect tool for the job, designed to help identify cables prior to connecting CATV, Satellite or other transmitting - receiving systems. But what happens if you lose the convenient twist-on speaker that is essential for toning? Don’t worry – we have a replacement! There is no need to purchase the entire tool when you can continue to use your existing PT-300 for testing and toning. Testing a cable is fast and easy. Simply plug the sender into a wall jack in a room. Back at the location where the cables meet, connect one cable at a time to the speaker device until you hear the tone… This means you’ve found your cable! You can also connect the toner without emitting a tone (a discretionary option).
