(Notes)
• Be sure to use a brand-new tape for the ME

SP VCO offset adjustment.

• Be sure to clean the head with a head clean-

ing tape before adjustment.

• The error rate should be measured with the

Viterbi OFF. The Viterbi is switched OFF au-
tomatically when the adjustment mode is
entered.

• The error rate value is displayed in decimal

form.

(1) Record a moving image in advance on the NEW

recording tape for 5 minutes.

(2)Select ADJUST MENU No. 106, "ME SP VCO".
(3)Playback the recorded tape, press the

[STOP] button to decrease the adjustment EVR
data and freeze the image. (Pressing the
[A.DUB] button simultaneously with the

button varies the adjustment value by

steps.)

(4)Increase the EVR data gradually until the block

noise just disappears. The current value is the
adjustment value "A".

(5)Playback the recorded tape and press the

[PLAY] button to increase the EVR data and fr-
eeze the image.

(6) Decrease the EVR data gradually until the block

noise just disappears. The current value is the
adjustment value "B".

(7)Calculate the intermediate value between the

"A" and "B" values.
(Since the adjustment values are hex numbers,
use a functional computation-capable calcula-
tor or the PC calculator provided in Accesso-
ries.)

C = (A + B)/2

Set the value "C" as the adjustment value.

(8)Playback the recorded tape again, confirm th-

at the error rate is within specification.

(9)Press the [SET] button to store the adjustment

data.
