standard to define the pairs. Connector pins
-6, -5 and - are the pairs defined by this
standard. The tester will display the "Pass"
icon when all 6 pins are correctly wired in a
one-to-one order. If all 6 pins are correctly
wired in the reverse order, the "Pass" icon
along with a flashing "Rev" icon will be
displayed. Standard telephone cables used
between a phone set and a wall jack are
usually reverse-pinned.
After turning on the telephone cable test
mode, subsequent presses of the TEL
button of less than  seconds long, forces
a new test cycle to begin immediately
upon release of the button. This is useful
to immediately begin a new test when
attaching a new cable to Testifier™. Holding
the TEL button down for more than 
seconds, turns the split pair test off. The
"Split" icon and the word "OFF" appearing
on the screen briefly indicate this. Another
long press will toggle back to the split pair
testing, and so on. When split pair testing
is not required, as in the testing of flat satin
cable, the split pairs can be turned off, so a
cable may pass based on continuity only.
