Items to be Checked, and ConditionsPossible causesD
HOST microcomputer (IC1001). Initialization of DV-related LSIs (IC5101, IC5202) has not been completed properly.(No is also displayed during playback of copy-prohibited sources or
Check the init indication: OK:Initialization of DV-related LSIs (IC5101, IC5202) appropriately completed NG:Communication failure between DV-related LSIs (IC5101, IC5202) and Check the number of DV devices when one DV device is connected to the recorder: 01:The connected DV device is correctly identified. Other than 01:The connected DV device is not correctly identified.Check of DV decoding when the recorder channel is set to DV: Yes:The recorder is in the process of a DV input operation No:The recorder is not executing a DV input operationCheck DEC: 525-60:An NTSC DV signal is input from the DV device. 625-50:A PAL DV signal is input from the DV device. No:No DV signal is input from the DV device.Check CGMS: 00:A copy-permitted source is being input. Other than 00:A copy-protected source is being input.Check SF: 32 khz: An audio signal with 32-kHz sampling frequency is being input. 48 khz: An audio signal with 48-kHz sampling frequency is being input. 44 khz: An audio signal with 44.1-kHz sampling frequency is being input.Check DVencode during DVD/HDD playback: Yes:The recorder is in the process of a DV output operation No:The recorder is not executing a DV output operation simultaneous-recording/playback.)
