JVC Maximize Your Cassette Player Experience with COMPU CAL Technology

·When the tape is played or recorded in the reverse direction (side B), only side B is played back or recorded and then the tape stops automatically.

DDRP (Dynamics Detection Recording Processor) record- ing

DDRP recording is performed with suitable JVC CD players and the recording level adjustment is performed automatically. Since recording level adjustment is performed automatically for different types of tape (normal, CrO2 and metal), the adjustment of INPUT LEVEL control is not required.

Read the instruction book of your CD player carefully.

COMPU CALIBRATION (COMPU CAL) FUNCTION

·This unit is equipped with a COMPU CAL function which can automatically set the flat frequency characteristics and optimal tape sensitivity for each tape in approximately 30 seconds. Calibration data is retained for each tape type (Type I, II or IV).

·Calibration data set with COMPU CAL is retained even if the power is turned off (or the power cord is unplugged), and the previous calibration data for the same type of tape as the new tape is recalled each time tapes are changed.

·Performing COMPU CAL operations again replaces existing data with the new data.

COMPU CAL operation

·Insert the tape to be recorded and press the COMPU CAL but- ton. During the operation, ``C''→ ``CA''→ ``CAL'' is displayed in the tape counter. When the operation finishes, the tape returns to its starting position, and the COMPU CAL indicator lights. COMPU CALIBRATION is now finished.

·Pressing the (stop) button part-way will interrupt the opera- tions.

·To recalibrate the unit, press the COMPU CAL button and wait for the COMPU CAL indicator to go out. Then, press the COMPU CAL button again.

Note:

If the tape is near its end, it will automatically stop and an error will be generated during operation. Therefore, be sure to check the time remaining on the tape (more than 2 minutes in the play mode) before starting the operations.

COMPU CAL Errors

·When the COMPU CAL indicator flashes, this indicates a COMPU CAL error.

·Press the (stop) button to stop the error indication.

Care should be taken for the following items as they are the cause of errors.

1)	Dirty heads	-Clean the heads.
2)	Scratches on the tape surface

-Replace with an undamaged tape.

3)When the tape ends part-way through the operations -Change the tape position.

4)In rare cases, tapes may have characteristics which fall out- side the COMPU CAL setting range.

·When an error occurs or when COMPU CAL operations are interrupted, calibration data cannot be stored in the memory. If settings were previously performed, the previous setting val- ues are retained.

·After confirming items 1) to 3) above and stopping the error

indication if there are no problems, even tapes which experi- ence errors can be recorded on using either 1 the unit's pre- set values or 2 previous setting values. (These are the values obtained by opening and closing the cassette holder one time.)

*Preset value: a standard value corresponding to each type of tape, which allows normal recording. (The pre- set value condition is in effect when the COMPU CAL indicator is unlit.)

Notes:

1.Since COMPU CAL operations record a test tone on tapes, previously recorded contents will be erased.

2.Using new tapes and cleaning the heads beforehand are recommended for optimal COMPU CAL operations.

3.Some variance in characteristics exists even with the same type of tape made by the same manufacturer. Therefore, when precise settings are desired, performing COMPU CAL operations for each recording is recommended.

4.To delete contents set with COMPU CAL, simultaneously press the REC/REC MUTE and B deck COUNTER RESET buttons. This deletes the calibration data for the type of tape currently inserted in the unit. Calibration data for other tape types is not deleted.
