CrO, tape
1. Connect the deck and the test equipments as shown in
Fig. 6-9,
2. Load a TEAC MTT-506 test tape.
3. Apply and record a test signal required in the Fig. 6-14,

4. With the simultaneous record/playback function, make
sure the readings on the AC voltmeter are within the
response limits.
5. In case of any deviation in the high frequency range of
the response limits, clean the heads and do again the
L307 setting described in step 11 in paragraph 6-6-2.

1. Connect the deck and the test equipment as shown in
Fig. 6-9.
2. Initially make sure that deck is set in specified record-
ing and playback condition.
3. Load the TEAC MTT-506 test tape.
4. Apply and record specified input level of —9 dB (275
mV) of 1 kHz signal for several seconds.
5. Then continue recording with no signal applied for a
few seconds.
6. Rewind the tape to the beginning of the 1 kHz signal
recorded portion.
7. Play and obtain the output level difference between the
1 kHz signal recorded portion and no signal recorded
portion.
