Timelapse recording is performed over very long periods of time which means that a durable tape is required.

When using VHS tapes, do not use tapes with recording times of more than 120 minutes (T-160/T-180 etc.).

For best results, use a T-120 tape.

• 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.

To obtain the best picture quality, use an HG (high
grade) tape (a JVC cassette is recommended).
Degradation of picture quality may result with some
types of tape. Make a test recording before
