V.LOCK ADJUST

If the picture shakes up and down during still play- back, adjust the picture by the following procedure.

1.Play back a tape, recorded in the 08 mode, in the still playback mode.

•With some TVs, if the V.LOCK buttons are pressed when playing a tape recorded in modes other than 08, shaking of the still pic- ture may not stop.

•When the FIELD REVERSE button is pressed in the still playback mode to set the VCR to the field reverse mode, the first several frame images may be distorted.

VISUAL SEARCH (High Speed Scan)

Note: The visual search function allows the re- corded material to be reviewed at 3, 5, 7 or 9 times the 08 hour speed mode.

1.Press the PLAY button.

2.Press the SEARCH (F.FWD) button to select the VISUAL SEARCH FORWARD mode, or press the SEARCH (REWIND) button to select the VISUAL SEARCH REVERSE mode.

3.Press the PLAY button again to resume normal

ALARM INDEX SEARCH

The alarm index search method causes electronic “marks” to be recorded on the tape at each point when the ALARM recording begins.

Later, the VCR can find these “marks” automatically, making it easy to find the beginning of each alarm for playback.

These check points are permanent until the tape is erased. A check mark is recorded automatically each time the VCR starts ALARM recording.

1.Press the PLAY button to start playback.

2.Press the ALARM INDEX button.

3.Press the REW or F.FWD button. The recorder enters VISUAL SEARCH mode.

4.When the VCR finds a mark, it enters normal playback mode.

5.Press REW or F.FWD button again to find next “marked” recording. The recorder advances tape to the next marked position.

6.Press the ALARM INDEX button again to release alarm index search.

Notes:

1.Be careful as no alarm input can be detected for 5 seconds immediately after the visual search mode is entered by pressing the REW or F.FWD button during the alarm index search mode.

2.When tapes recorded by other VCRs are played in the alarm index search mode, the VCR may enter the play mode in a meaningless position.

3.When you have selected “MANUAL” at the DURATION setting in the ALARM display and the duration of an alarm recording is shorter than the values shown below, “marks” may not be detec- ted.
