1) Input the audio signal (400Hz, -8dBs) into the Audio line
IN/OUT terminal, and record.
2) Connect the valve voltmeter (oscilloscope) to the Audio
line IN/OUT terminal.
3) Play back the record, and ascertain that the output
waveform level is -8 dBs
±
4 dBs (580 to 1370 mVp-p on
the oscilloscope).
4) If there is any deviation from the specified value, perform
adjustment again as stated in items 1) above, and check
again the self-recording/playback level.

1) Set the alignment tape (JiGWR5-5CSP)
2) Using the adjustment remote controller (RRMCG0033TASA),
set the VCR adjustment mode, and set the address “21” with
the operation switch (FF/REWIND key).
3) Play back the standard tape.
4) Using the operation switch (FF/REWIND key), make an
adjustment so that the most clear playback waveform is
obtained on TL605.
5) Press the operation switch (PLAYBACK key) to write the
data.
6) Press the operation switch (STOP key) to exit from the
address “21”.
(The address “21” blinks.)
