2. Verify that the pair is actually split with another pair, and then locate the
second split pair with a tracing tone probe or other standard method.

pairs exactly as shown in the connection diagram (Figure 4-10).
4. Press K.
Note
The two split pairs must be the same lengths (within ±5 %) to obtain a
