Its functions are described below.. Manual test A mode which drives the motor only while the switch is ON. It enables the operator to control the motor as desired.. Step test A mode which drives the motor until the current condition detected by the sensor changes to another condition. It enables the movements made by the motor in each operation to be controlled while being checked.. Auto test A mode that checks if the mechanism operates normally according to the condition shift table recorded in the unit for each mechanism deck. All the conditions of the decks are checked through a series of operations. An error message is displayed if incorrect shifts and conditions are detected and operations are stopped. -. MECHANISM CONDITION (POSITION) SHIFTING ORDER LIST After selecting the mechanism deck, select one of the two test modes other than the auto test, and press the RVS and FF button to specify the mechanism state (position).

FWD POSITION CHECKING AND ADJUSTMENT Checking / adjusting method Bend the TG adjustment plate with the bending stick (J-) so that the TG flange external circumference, including fluctuation, is within the gauge range while the TG adjustment jig (J-7) runs in the FWD mode. TG should be within the gauge. Insert the bending stick (J-), rotate left and right to adjust the TG position. Adjustment position TG TG arm assembly TG adjustment jig (J-7) FWD mode Gauge TG adjustment plate assembly -. FWD BACK TENSION CHECKING AND ADJUSTMENT Checking / adjusting method Check the gauge value (reel table (S) side) of the mini DV torque cassette (J-0) in the FWD mode. Adjust the position of the TG spring hook so that the gauge value satisfies the specified value. If the specified value is not satisfied, hook the TG spring hook claw to the middle position, and check that the FWD position is correct. If not correct, adjust the FWD position again, and check the FWD back tension again. If smaller than the specified value, hook in the counterclockwise direction. TG spring hook If greater than the specified value, hook in the clockwise direction. Tension coil spring (TG) If the FWD position is correct but the specified value for the FWD back tension is not satisfied, replace the tension coil spring (TG), and perform this adjustment again. (For details on how to replace, refer to "-6. Tension coil spring (TG)".) If the fluctuations of the FWD back tension are great and the specified value is not satisfied, replace the reel table S assembly. (For details on how to replace, refer to "-.

PREPARATION FOR TAPE PATH CHECKING AND ADJUSTMENT Preparations before adjustment (Connection and Setting). Clean the tape running side. (Refer to 5-. Cleaning of Tape Path System.). Connect the adjusting remote commander (J-), and input the setting value of the model. The setting value differs according to the model. Refer to the respective service manual. For DCR-TRV9/TRV9E Page : Address : C Data : 07 Adjusting remote commander (RM-95) Preparations before adjustment (Preparing an exclusive tracking tape (J-9)) Remove the lid of the cassette due to the C mechanism structure. Assemble without this part. Cassette lid. Connect an oscilloscope. The connecting state differs according to the model. Refer to the respective service manual.. Play the tracking tape (J-9) (Exclusive), and check the states at the entrance and exit of the RF waveform. If not flat at either side, perform the adjustments from Flowchart Adjustment start- on page 8. Normal Torsion spring This is to prevent the lid from rising when the damper is removed so that it does not come in the way of the mirror (J-) inserted, when checking the slack and curl between the capstan and TG7. Faulty entrance side Faulty exit side Exclusive tracking tape 0

21 -5. TRACK CHECKING AND ADJUSTMENT Checking / adjusting method Run the tracking tape (J-9) in the PLAYBACK mode, and check that the RF waveform is flat at both the entrance and exit. PLAY mode If not flat If the waveform at the entrance is bad, rotate TG. If that at the exit is bad, rotate TG6 to flatten the waveform. Faulty entrance side Entrance side Normal waveform Exit side Faulty exit side TG Blast screw TG6 Blast screw Tips for adjustment The tape path waveform at the entrance and exit should both be flat, or that at the entrance should be slightly raised and that at the exit should be lowered. If that at the entrance is slightly lowered especially, problems such as sound drop may occur. Drum Raised at the entrance. Lowered at the exit. If the waveform does not become flat even if the guides are rotated at the entrance and exit, the characteristics may be faulty of the tracking tape with time. Check again using a new tracking tape. If the waveform still does not become flat, the coaster assembly and drum base block assembly may be faulty. (For details on how to replace, refer to -. Drum Base Block Assembly or -9. GL Block Assembly.) -6. TG7 SLACK CHECKING AND ADJUSTMENT Checking / adjusting method Run the tracking tape (J-9) in the REV mode, and visually check from right above the slack between the capstan and TG6. If the slack is great, rotate TG7 to satisfy the specified value. If the slack occurs If the slack can not be corrected, the TG7 arm block assembly may be faulty. (For details on how to replace, refer to -6. TG7 Arm Block Assembly.) REV mode TG6 Capstan Drum Check the slack between here. Tolerance : ±0. mm (Visually) TG7

22 -7. CURL CHECKING AND ADJUSTMENT Checking / adjusting method Run the tracking tape (J-9) (exclusive) in the CUE mode or REV mode, and check that the tape runs along each flange. Also check that there are no large curls on each tape guide. There should be no large curls on the upper flange of TG and TG6. TG TG TG TG Drum TG5 TG6 TG7 If the curl is large or there are clearances If the TG curl is large or clearances exist, replace the coaster (S) assembly. If the TG6 curl is large, or clearances exist, replace the coaster (T) assembly. If curls or clearances exist on the TG7, rotate TG7 and adjust its height. Note :Be careful not to rotate TG7 excessively. For details on how to replace the coaster (S) / (T) assembly, refer to - on page 6. There should be no large curls on the upper and lower flanges of TG7. Coaster (S) assembly TG TG TG5 TG6 Capstan Use a mirror (J-) for checking for TG7. Easy to check with removing the damper assembly. (Refer to-. Damper Assembly on page 9.) TG Drum Coaster (T) assembly TG TG7-8. CUE / REV CHECK Checking method Run the tracking tape (J-9) in the CUE mode or REV mode, and check that the intervals of the waveform peaks are consistent. CUE mode -9. RISING CHECK Checking method Check that when the tracking tape (J-9) is switched from the STOP, CUE, REV, FF, REW modes to the PLAYBACK mode, the waveform rises horizontally within seconds. Perform this or times. Mode changes STOP PLAYBACK CUE PLAYBACK REV mode REV FF PLAYBACK PLAYBACK When switching the modes, the waveform should rise within seconds or times. REW PLAYBACK If not even If the waveform peaks are not even, perform "Tracking adjustment" again. Check after checking rising Check that the tape loads and unloads smoothly. Play a self-recorded or already recorded tape, and check that the sound and images are normal.

23 5. PERIODIC CHECK Carry out the following maintenance and periodic checks not only to fully display the functions and performance of the set, but also for the equipment and tape. After repairing, service the set as follows, regardless of the length of use. 5-. CLEANING OF ROTARY DRUM ASSEMBLY. Press a wiping cloth (J-.) moistened with cleaning fluid (J-.) against the rotary drum assembly gently, and clean it while rotating the rotary drum assembly slowly with your finger in the counterclockwise direction. Note :Do not rotate the motor on power or rotate the rotary drum assembly in the clockwise direction with your finger. The head tip will also be damaged if the wiping cloth is moved perpendicularly against it. Therefore, be sure to follow the above instructions when cleaning the rotary drum assembly. 5-. CLEANING OF TAPE PATH SYSTEM. Clean the tape path systems (TG to TG7 and capstan) and the lower drum using a super fine applicator (J-.) moistened with cleaning fluid. Note :Make sure that no oil or grease of the link mechanisms sticks to the super fine applicator (J-.). Note :Do not use a applicator moistened with alcohol to the other guide cleaning. But clean the pinch roller using alcohol. TG TG TG5 TG6 TG TG Drum Pinch roller Capstan TG7 Rotary drum assembly Wiping cloth 5-.

Note :Greasing Always use the specified grease. If the viscosity differs, various problems may occur. (Use SG-9 for all parts of the C mechanism.) Check the quantity of grease when installing the parts which is needed to apply the grease.
