1-3 Precautions
5 Handle the unit carefully
• Do not place anything heavy on the unit (a monitor,
etc.). A malfunction may occur.
• Do not put any foreign substance into the cassette
loading slot.
• Avoid violent shocks to the recording chassis during
transportation. Remove the cassette tape from the unit
for transportation.
5 Turn off the power to save electricity when not using the
unit.
Handling and storage place
5 Avoid using the unit in places subject to the
following conditions:
• extreme heat or cold
• strong magnetic fields (do not use a transceiver within
2 meters of this unit)
• high humidity
• dust and soil
• vibrations
• variations in temperature
5 Use this unit in horizontal (flat position) only.
5 Do not leave the unit in the Still or Record Pause
mode for a long time as this may damage the tape.
To minimize tape damage, this VCR automatically
enters the Stop mode after about 5 minutes have
passed in the Still or Record Pause mode.
Video cassette
• Only use video cassette bearing the mark.
• To prevent accidental erasure of a recorded tape, break
the erasure prevention tab on the cassette. To use a
cassette with a broken tab, place a piece of cellophane
tape over the broken tab.
• Video cassettes cannot be used upside down.
• Leaving the tape in a partially wound condition for a long
time may damage the tape. Rewind the tape to the
beginning before storage.
Timelapse recording is performed over very long periods of time
which means that a durable tape is required.
Use a T-160 tape or shorter.
Do not use extended tapes (180 minutes or more such as T-180).

or in an area directly exposed to a

5 Condensation
When cold beer is poured into a glass, water drops
appear on the glass’s surface. This phenomenon is
called “condensation”. When condensation occurs on
the VCR’s head drum and tape guides it may damage
the tape.
