(DENON GR-2/60)
(9) Transport Check cassette tape (A-BEX TCC-902)
(10) Lead line with alligator clip
e Caution on adjusting
(1) Before adjusting, clean the head surface, capstan and the

1. Tape Transport Check
Load the transport check cassette. In the operational mode,
illuminate the fixing guides of the R/P HEAD with a lamp and
check to make sure the tape edge does not come in contact with
the tape guide section.
The tape transport is the most important element in determining
the performance of a cassette deck.
Avoid moving the various adjustment screws, nuts, etc., as much
as possible. Refer to the pages on “Adjusting and Checking the
Mechanism
Section”
when
replacing
or
adjusting
the
R/P
HEAD.
2. Adjusting the Azimuth
(1) After completing the tape transport check, load the test tape
(A-BEX TCC-153).
(2) Playback the test tape; adjust the azimuth screw so that
section 4 of the resurge wave form is maximum and section
B is minimum.

3. Checking and Adjusting the Tape Speed
{1) Connect the frequency counter to the LINE OUT terminal and
load test tape (SONY TY-224).
(2) Load cassette tapes on both cassette decks A and B. Next, on
the deck (A or B) whose speed is to be adjusted, while holding
down the PLAY, FF and REW buttons together, press the
POWER switch. After the power has been on for abouttwo sec-
onds, the Remote Control Indicator “Ml” in Display will fight up
and the cassette deck will begin to play in speed adjustment
mode.
(Speed adjustments can not be made, unless this mode is first
selected.)
(3) At first high speed adjustments, press the DUBBING SPEED
“HIGH” button and use Meter Unit RT554 for Cassette Deck A
and RT552 for Cassette Deck B.
Next normal speed adjustements, press the DUBBING SPEED
“NORMAL” button and use Meter Unit RT553 for Cassette Deck
A and RT551 for Cassette Deck B.
(Note that speed adjustment mode is cancelled when the tape is
ejected.)
