SAFETY PRECAUTIONS
Do not point the lens or the viewfinder directly into the sun. This can cause eye injuries, as well as
lead to the malfunctioning of internal circuitry. There is also a risk of fire or electric shock.
CAUTION!
The following notes concern possible physical damage to the camcorder and to the user.
When carrying, be sure to always attach and use the provided hand strap. Hold the camcorder
firmly in your hand, with the strap securely around your wrist. Carrying or holding the
camcorder by the viewfinder and/or the LCD monitor can result in dropping the unit, or in a
malfunction.
Take care not to get your finger caught in the cassette cover. Do not let children operate the
camcorder, as they are particularly susceptible to this type of injury.
Do not use a tripod on unsteady or unlevel surfaces. It could tip over, causing serious damage to
the camcorder.
CAUTION!
Attaching the camcorder to the Docking Station with cables (Audio/Video, S-Video, Editing, DC,
etc.) connected, then leaving it on top of the TV is not recommended, as tripping on the cables will
cause the camcorder to fall, resulting in damage.
This camcorder is designed exclusively for the digital video cassette and MultiMediaCard. Only
cassettes marked "
" and memory cards marked "
" can be used with this unit.
Before recording an important scene . . .
.... make sure you only use cassettes with the Mini DV mark
.
.... make sure you only use memory cards with the mark
.
.... remember that this camcorder is not compatible with other digital video formats.
.... remember that this camcorder is intended for private consumer use only. Any commercial use
without proper permission is prohibited. (Even if you record an event such as a show, perform-
ance or exhibition for personal enjoyment, it is strongly recommended that you obtain permis-
sion beforehand.)

ABOUT DV
The digital camcorder converts incoming audio and video signals into digital form for recording.
A video signal is composed of a luminance signal (Y) and colour signals (R-Y and B-Y). These signals are
identified and recorded digitally (Digital Component Recording). The A/D (Analogue to Digital) converter
samples the Y signal at 13.5 MHz, and R-Y and B-Y at 6.75 MHz, and changes them to an 8-bit quantum
signal.
Sound sampled at 48 kHz is changed to a 16-bit quantum signal, and sound sampled at 32 kHz is converted to
a 12-bit signal.
3 Audio Area
The digital audio signal is recorded here.
4 ITI (Insert and Tracking
Information) Area
Insert editing and post-recording editing
tracking signals are recorded here.
1 Sub-Code Area
The Time Code and Date/Time data are
written here, separate from the video data.
This enables you to display the date and
time during playback, even if they weren't
displayed while recording.
