Self-diagnostics function
The unit has a self-diagnostics display function.
This function displays the current condition of the unit
as a five-digit code (a combination of a letter and
numbers) on the analog video output. If a five-digit
code is displayed, check the following code chart. The
last two digits (indicated by
ss
) will differ depending
on the state of your unit.
If you are unable to resolve the problem, or a code
other than those in the above chart appears, contact
your Sony dealer or local authorized Sony service
facility and inform them of the number.

Compatibility of DVCAM and DV Format
The DVCAM format was developed as a more reliable and higher end
format than the consumer DV format. Here we explain the DVCAM and
DV formats: the differences, compatibility and limitations on editing.
Differences between DVCAM and DV format
1) There are two modes for audio recording; Lock mode and Unlock mode. In
Lock mode, the sampling frequencies of audio and video are synchronized. In
Unlock mode, which the consumer DV format adopts, the two sampling
frequencies are independent. The lock mode maintains high compatibility with
the higher formats and is more effective than unlock mode in digital processing
and smooth transition during audio editing.
2) This unit cannot record in DV format with 16 bit – 32 kHz or 44.1 kHz.
3) The user bits cannot be set on this unit.

DVCAM and DV cassettes
Both DVCAM and DV cassettes can be used on DVCAM or DV video
equipment. The recording format is defined according to recorder format
as described below.
• This unit can record in DV format. (SP mode only)
• This digital videocassette recorder complies with the DVCAM format.
Though DV cassettes can be used for recording, we recommend that you
use DVCAM cassettes. Particularly when you use a Mini-DV cassette
that is longer than 60 minutes, do not play back the tape repeatedly (i.e.,
when editing). Set STILL TIME to 1 MIN or 30 SEC (See page 43 (GB)),
and FROM REC P to STOP (See page 44 (GB)).
• If you use a DV cassette to record images in the DVCAM format, the
recording time will be reduced to 2/3 of the time indicated on the DV
cassette.
• If you use a DVCAM cassette to record images in the DV format (SP
mode), the recording time will be extended to 1.5 times the time indicated
on the DVCAM cassette.
Compatibility on playback
Some tapes cannot be played on DVCAM or DV video equipment.

Compatibility on editing using a DV connection
When this unit is connected to other DVCAM or DV video equipment
using DV connectors, the recording format of an edited tape is defined
according to the recorder format as described below.
1) On this unit, only DV-formatted tapes recorded in the SP mode can be used as
source tapes.
2) This unit will be restricted according to the REC MODE setting on the VTR
SET menu.
3) When you copy a DV-formatted tape using DVCAM video equipment, the
recorded format of the copied tape is the following DVCAM format.
• The audio recording mode of the copied tape is unlock mode.
• The time code of the copied tape is partly inaccurate.
4) If you use a DVCAM-formatted tape as described in 3) above, the audio
recording mode of the recorded tape is unlock mode and the time code is partly
inaccurate.
5) Some DV video equipment may be able to play back a DVCAM-formatted
tape. Even if the tape is played back, the contents of the playback cannot be
guaranteed.
6) The audio recording mode of the edited tape is lock mode.
7) Depending on the signal conditions of the source tape, you may not be able to
edit the tape using the DV connection.
Limitations on editing
You will find the following limitations when editing.
• Due to differences of track pitch, you cannot record or edit DV-formatted
tapes using DVCAM video equipment.
• Depending on signal conditions, you may not be able to record or edit
DVCAM-formatted tapes. In these cases, copy the tape again using
analog audio/video jacks.
