Notice on moisture condensation
Moisture may condense on the drum assembly if the set is moved directly from a
cold to a warm location or if the set is used in a very humid place. This may cause
damage to the tape to adhered the head drum. To avoid this, take the following
precautions.
e When the set is moved directly from a cold to a warm location, be sure to remove
the cassette.
e Before inserting a cassette, set the POWER switch to ON and check that the
HUMID indicator on the display window does not light. If it lights, wait until the
HUMID indicator goes off before inserting a cassette.
¢ If it seems that moisture has been condensed in the VTR with the cassette inserted,
proceed as follows:
1 Set the CAMERA/VTR switch to VTR SAVE.
2 Turn on the unit.
3 When the HUMID indicator lights up, press the & EJECT button and remove the
cassette.
When the indicator does not light, there is no condensation.
Cleaning the heads
Use the BCT-5CLN cleaning cassette to clean the heads. Carefully read the instruction
manual furnished with the BCT-5CLN. Excessive or incorrect use of the cleaning
cassette may shorten the head life.
47 (E)

Do not use the unit in extremely hot or cold locations or in places where the humidity
is high. The unit is designed to operate in temperatures ranging from O°C to 40°C
(32°F to 104°F). Avoid sudden temperature changes, particularly from an extremely
cold location to a warm one, as this is conductive to condensation of moisture on the
head drum assembly.
¢ Do not subject the unit to unnecessary vibration when carrying it.
e If the unit is not used for an extended period of time, remove the battery pack.

To check the last scene of the previous recording (recording review)
Press the RET button on the lens after recording.
The last two seconds of the recorded scene are played back and then the unit will
enter the standby mode.
When the RET button is kept pressed, the last recorded picture can be seen for a
maximum 10 seconds.
Recording review is possible only when the recording is longer than one second.
Frame-accurate backspace editing
As long as the cassette is not ejected, frame-accurate backspace editing can be made
when the CAMERA/VTR switch on the camera is set to the VTR STBY.
Even if the CAMERA/VTR switch is in the VTR SAVE position, the unit will go into the
frame-accurate backspace editing by simply pressing the VTR or VTR START button.
In this case, however, it takes a little longer to start recording (approx. 3 seconds).
To start frame-accurate backspace editing after the power has been turned off or the
cassette has been ejected, or to record on a previously recorded tape, proceed with
the following steps.
1 Find the point you want to start editing by monitoring the viewfinder screen, and
stop the tape.
2 Press the RET button on the lens.
The starting point will be searched for.
3 Press the VTR or VTR START button.
Editing will begin.

¢ The FILTER/AUDIO indicator in the viewfinder shows the
level responding to the peak signal. When a sine wave is
input and the level meter pointer deflects to OVU, the
indicator is designed to indicate 3. When audio signals
are input and the level meter pointer deflects to around
OVU, the indicator indicates 4.
The viewfinder indication corresponds to that of the level
meter as follows;
