  • DSS-01 coax cable tester
  • F-81 barrel connector
  • One standard AAA battery
How do you use the DSS-01?

The DSS-01 connects to a coax cable or coax outlet by pushing on the F-connector and pressing one button to test the connection for valid signals from your Cable Broadband provider.

Where can I find instructions on how to use the DSS-01?
The actual instructions on printed on the DSS-01.
Is there voltage protection built in to the DSS-01?
Yes, there is built-in voltage protection in the DSS-01 up to 4K volts.
What signals can the DSS-01 detect?

The DSS-01 detects valid signals from your Cable Broadband provider that occur between frequency ranges of 88MHz to 1GHz. It is not designed to detect MoCA or satellite signals.

Will the DSS-01 be able to detect through a splitter?

Yes. The DSS-01 tests and detects a specific range of signals and does not test for voltage.

How many scans can be performed on one battery?

The DSS-01 performs approximately 100 scans on a single AAA battery. 

How big is the DSS-01?

The DSS-01 is compact and pocket-sized. It’s approximately 2.5 inches in length and 1 inch in width.

Will the DSS-01 help me to self-install cable internet?

Yes, most definitely. The DSS-01 is specifically designed to detect the valid signals from your Cable Internet provider, thereby enabling you to detect operational coax outlets and wiring in your home that are ready to receive a cable modem.

Is this a one-person test?

Yes. The DSS-01 is small and compact to fit easily into your hand for one-person testing in very tight areas, without any problems.

I am always getting a Red light with the DSS-01, what should I do?
  • Make sure the AAA battery is in good working order (has a charge)
  • Check that all of your connections are tight/secure
I’m having problems installing the battery
  • Removing the cover for the battery may be stiff and you may need to push with your thumb on the one end to slide it open with a small degree of force. The cover slides to the side and then slightly forward to unhinge two tiny hinges that help to hold the cover in place.
  • Closing the cover for the battery may be tricky – you may need to look at where the small pins are located at the top and bottom of the cover to ensure they are lined up to click in when sliding the cover back into place.
