Please use a 2HD (1.44MB) or 2DD (720KB) blank disk that was
formated by A5000/A4000 or formated for MS-DOS. Be sure that
the write protect of the prepared blank disk is OFF. Please use a
correctly formated disk. An imperfectly formated disk (In case of
taken the disk out on ther way to the formatted.) or an old and wasted
disk tends to make the result NG.

11 1 kHz STEREO OUT-L
Insert the appropriate phone plugs into the STEREO OUT-L, R,
ASSIGNABLE OUT-L, R, PHONES terminals. Check the output
waveform and the output level of each output by using an oscillo-
scope, an AC voltmeter (with JIS-C filter) and a distortion factor
meter. The MASTER VOLUME control must be set at maximum for
these checks.
STEREO OUT-L: 1 kHz +/- 1 Hz, sine wave, less than 0.2% distortion
-1 +/- 3 dBm (10 k ohm load)
STEREO OUT-R: less than -75 dBm (10 k ohm load)
PHONES (L):
sine wave, less than 3% distortion, +7 +/- 3 dBm
(33 ohm load)
PHONES (R): less than -60 dBm (33 ohm load)
While sounding, the LCD shows as belows.
