Sony DSR-250 User Manual

Note
Internal parts of the camcorder may become bent or otherwise damaged if you attempt
to insert a mini-size cassette in the wrong direction (such as with the cassette turned
backside front so the reel holes face the cassette holder window or with the cassette
turned sideways so that a short side enters first).

When you use cassettes with cassette memory
Read the instruction about cassette memory to use this function properly (p. 158).

To prevent accidental erasure
Slide the REC/SAVE switch on the cassette to the SAVE position.

If Q flashes even if the cassette has been inserted
Insert the cassette again.
