Gale Corporation’s proprietary f-male to RJ-11 2-pin adapter; DTD is designed to indicate, via LEDs, the presence of dial tone voltage and reversed pairs. This great adapter virtually eliminates the need for a telephone butt set.
Out of all our exclusive patented adapters, the Dial Tone Detective™, is easily the most exhilarating advancement of all.
This low-cost and compact (1 ¾” long) adapter virtually eliminates the need to carry an expensive and cumbersome test phone set (i.e., Butt Set) to determine the presence of dial tone!
Simply insert the modular plug portion of the DTD directly into a telephone jack.
The bi-colored LED inside the DTD will immediately light green if the phone line has a proper dial tone. If the LED lights red, then there is dial tone but the wires in the jack are reversed and should be corrected.
