Check points
• The REMOTE/LOCAL switch of a VTR is set to LOCAL. (See page 12.)
• The VTR is not turned on. (See page 12.)
• Are the connections made firmly? (Insert the connectors firmly in position.) The
counter number for the disconnected player or recorder will not be indicated.
(See page 11.)
Unless the CTL signal is recorded on the tape, the figure will not change on the
counter. (See page 13.)
• Is the inserted cassette set in the REC INHIBIT mode?
• Are the connections made firmly? (Insert the connectors firmly in position.) (See
page 11.)
• Does the tape reach to the end? (Rewind the tape).
• Is the INPUT SELECT switch of the videocassette recorder set correctly?
• When insert editing, press the INSERT select button correctly. (See page 15.)
• When insert editing, record the CTL signal on the tape before editing.
• When assemble editing, record the CTL signal before the first IN point.
• Are the IN lamp and OUT lamp blinking alternately? (Re-enter the editing points
correctly.)
• After entry of the edit points, was the time counter not reset to "0"? (See pages 6,
and 17)
• The memorized points and the actual editing points may be different slightly
according to the recorder used. (Make fine adjustment with the TRIM button
before editing.) (See page 19.)
• If the CTL signal breaks at that position, the picture will be unstable. (See page
13.)
• If the recording is started with the REC button, the picture will be unstable. (Start
recording with the AUTO EDIT/END or EDIT button.)
The guard band noise (lateral stripes) which appears on the playback picture
except at normal speed is not malfunction.
• Does not the external signal applied to the VTR contain noise? (Re-select the
position of the INPUT SELECT switch.)
• When insert editing, if the recorded CTL signal is not normal or contains noise,
the playback picture will be unstable. (See page 13.)
• If the player is in the picture search mode, the playback picture of the recorder
may be unstable. (Set the player in the normal playback or STILL mode.)
Adjust the vertical and horizontal hold controls on the video monitor.
