Explanation of Terms ª Digital Video System In a digital video system, images and sounds are converted into digital signals and recorded on a tape. This complete digital recording is capable of recording and playback with minimal image and sound deterioration. In addition, it automatically records data, such as Time Code and date/time, as digital signals. Compatibility with S-VHS or VHS Cassettes Because this Palmcorder employs a digital system for recording image and sound data, the cassette is not compatible with conventional S-VHS or VHS video equipment that employs an analog recording system. The size and shape of the Cassettes are also different. Compatibility with Output Signals Because AV signal output from the AV signal output jack is analog (the same as conventional video systems), this Palmcorder can be connected with S-VHS or VHS VCR or a TV for playback. (l 50, 67) ª Focus Auto Focus Adjustment The Auto Focus System automatically moves the internal focusing lens forward or backward and adjusts the focus so that the subject can be seen clearly. However, the Auto Focus System does not function properly for the following subjects or under the following recording conditions. Please use the Manual Focus Mode instead. 1) Recording a subject whose one end is located closer to the Palmcorder and the other end farther away from it ≥Because Auto Focus makes adjustments at the center of an image, it may be impossible to focus on a subject that is located in both foreground and background. 2) Recording a subject behind dirty or dusty glass ≥Because the focus is on the dirty glass, the subject behind the glass will not be in focus. 3) Recording a subject in dark surroundings ≥Because the light information that comes through the lens decreases considerably, the Palmcorder may not focus correctly. 4) Recording a subject that is surrounded by objects with glossy surfaces or by highly reflective objects ≥Because the Palmcorder focuses on the objects with glossy surfaces or on highly reflective objects, the recording subject may become blurry. 5) Recording a fast-moving subject ≥Because the focus lens inside moves mechanically, it may not be able to keep up with the fast-moving subject. 6) Recording a subject with little contrast ≥Because the Palmcorder achieves focus based upon the vertical lines of an image, a subject with little contrast, such as a white wall, may become blurry. 97

Do not attach anything other than the MC
Protector (optional) or the ND Filter (optional) on
the Lens Hood.
When you want to attach a Tele Conversion Lens

supplied), be sure to first remove the lens Hood by
turning it counter-clockwise. When reattaching the
Lens Hood, insert

and turn it
clockwise.
If you push the [W/T] Lever toward [W] during
recording with the filter or conversion lens
attached to the Palmcorder, the 4 corners of the

Digital Video System
In a digital video system, images and sounds are
converted into digital signals and recorded on a
tape. This complete digital recording is capable of
recording and playback with minimal image and
sound deterioration.
In addition, it automatically records data, such as
Time Code and date/time, as digital signals.
Compatibility with S-VHS or VHS Cassettes
Because this Palmcorder employs a digital system
for recording image and sound data, the cassette is
not compatible with conventional S-VHS or VHS
video equipment that employs an analog recording
system.
The size and shape of the Cassettes are also
different.
Compatibility with Output Signals
Because AV signal output from the AV signal output
jack is analog (the same as conventional video
systems), this Palmcorder can be connected with
S-VHS or VHS VCR or a TV for playback.

Focus
Auto Focus Adjustment
The Auto Focus System automatically moves the
internal focusing lens forward or backward and
adjusts the focus so that the subject can be seen
clearly.
However, the Auto Focus System does not function
properly for the following subjects or under the
following recording conditions.
Please use the Manual Focus Mode instead.
1)
Recording a subject whose one end is
located closer to the Palmcorder and the
other end farther away from it
Because Auto Focus makes adjustments at
the center of an image, it may be impossible to
focus on a subject that is located in both
foreground and background.
2)
Recording a subject behind dirty or dusty
glass
Because the focus is on the dirty glass, the
subject behind the glass will not be in focus.
3)
Recording a subject in dark surroundings
Because the light information that comes
through the lens decreases considerably, the
Palmcorder may not focus correctly.
4)
Recording a subject that is surrounded by
objects with glossy surfaces or by highly
reflective objects
Because the Palmcorder focuses on the
objects with glossy surfaces or on highly
reflective objects, the recording subject may
become blurry.
5)
Recording a fast-moving subject
Because the focus lens inside moves
mechanically, it may not be able to keep up
with the fast-moving subject.
6)
Recording a subject with little contrast
Because the Palmcorder achieves focus
based upon the vertical lines of an image, a
subject with little contrast, such as a white
wall, may become blurry.
