Description: Abnormal speed of tape running is detected during fast-forward or rewind.
Sub messages and detecting conditions:
(1) S-REEL Side Trouble (FF)
When the tape running speed is insufficient with respect to the target speed continuously
for a certain period of time, and the S side tension is above the specified value during
forward. (The cause should be at the S reel side.)
(2) T-REEL Side Trouble (FF)
When the tape running speed is insufficient with respect to the target speed continuously
for a certain period of time, and the S side tension is below the specified value during
forward. (The cause should be at the T reel side.)
(3) S-REEL Side Trouble (REW)
When the tape running speed is insufficient with respect to the target speed continuously
for a certain period of time, and the S side tension is below the specified value during
rewind. (The cause should be at the S reel side.)
(4) T-REEL Side Trouble (REW)
When the tape running speed is insufficient with respect to the target speed continuously
for a certain period of time, and the S side tension is above the specified value during

. S side or T side reel brake solenoid drive circuit (DR-307 board) malfunction.
. Servo adjustment is faulty for reel.
. Height adjustment is faulty for reel table.
. Cassette compartment defective or installation of it is faulty.
(The reel stopped rotating because of the rising of the cassette tape from its reference
position.)
. Clearance adjustment is faulty for S side or T side FG detection block.
. Trouble of tape path, drum and the same.
