Sanyo DTL-4800 instruction manual Tape Management Function, Operation

TAPE MANAGEMENT FUNCTION

This VCR is equipped with a tape management function. Using this function you can protect previous recordings and prevent overuse of the tape by controlling the tape protection term (number of days), the maximum number of re-recordings of the tape and the recording group. To use the tape management function, it must be set before recording is started. The tape management data is recorded at the beginning of the tape. For details on how to set this function, refer to “Setting the Tape Management Function”.

PROTECT DAY: To set the number of days before the tape can be rerecorded over.

REC PASS SET: To limit the number of rerecordings, in order to maintain a good image quality.

GROUP NO.:	To manage tapes belonging to different
	recording groups.

NOTE:

œBefore using this function, make sure that the clock is set properly.

Operation

When recording is started, the VCR will rewind the tape to the beginning, and will playback some of the tape to check for the presence of tape management data (no image is displayed). While the presence and type of data are checked, the message “T. MANAGE. CHK” is displayed on-screen.

NOTES:

œWhen a program timer recording is set, the tape management data is checked after the TIMER button is pressed to complete the program timer recording setting.

œWhen performing trigger shot recording and alarm recording, the tape management function will not operate even if it is active.

If no tape management data is present on the tape

Recording will start according to the settings in the (TAPE MANAGEMENT) menu.

When recording starts, the updated tape management data is recorded onto the tape.

If the tape has already been recorded on, the message “USED TAPE” will flash on-screen until recording starts.

If a conflict is found when the tape management data is checked, the (TAPE MANAGEMENT) menu is displayed and the conflicting setting will flash. This menu will show the settings taken from the data recorded on the tape and not the current data settings held in the VCR’s (TAPE MANAGEMENT) menu setting. Refer to “Tape Management Conflict Display” for detailed information.

NOTES:

œDuring Autorepeat recording, the tape management data at the beginning of the tape will be checked and updated every time the tape is rewound to the beginning. However, the “PROTECT DAY” setting will be ignored. Also, even if there is a conflict with the “REC PASS SET” number, autorepeat recording will continue without any warning.

œIf the VCR is set for alarm recordings, alarm recording will be done based on the different settings.

If an alarm trigger is received while the tape is being first rewound, the tape will continue to be rewound to the beginning, then alarm recording will be done after the tape has been advanced of a preset duration.

If an alarm trigger is received while the message “T. MANAGE. CHK” is displayed on-screen, in order to prevent erasing the tape management data recorded at the beginning of the tape, the tape is advanced of a preset duration, then alarm recording starts.

If an alarm trigger is received while tape management data is being recorded onto the tape, alarm recording will only start after all the data has been recorded.

Furthermore, when setting a program timer recording, in order to protect the data, no alarm trigger will be received until the first program timer recording starts.

IMPORTANT NOTES:

œIf the tape management data cannot be read, the VCR will switch to stop mode and “DATA NG” will be displayed on-screen.

This may indicate that the beginning of the tape (data recording/reading section) is damaged and the tape may be unusable.

The message “DATA NG” will disappear when the EJECT, STOP or PLAY button is pressed.

œSet the security lock function to on in order to protect the security of this feature.

If tape management data is present on the tape

The tape management data is checked and if there is no conflict, the VCR will rewind the tape to the beginning, then recording starts and the updated tape management data is recorded onto the tape. While the tape is rewound and the tape management data recorded, the message “T. MANAGE. OK” is displayed on-screen.
