Step 5 requires you to measure the time taken to play a section of 3150Hz tone from test tape 339 280 009. The tone should last for 100 seconds (once around the clock face +40 seconds from the graphic) with an allowable tolerance of +/- 0.5 seconds.
If you don't have the test tape, you could record 100s of tone using a known good recorder, perhaps.
