Pointers
- Always do a test recording before you do actual recording.
- Always look at VCR on TV when setting up to record. Make sure are seeing the input to VCR and not just the channel you want to record on the house system. The VCR could be mistuned and you will never know it if you don't look through the VCR.
- Check ITV's website for monthly schedule updates and changes: http://www.itv.scetv.org/updthome.htm.
- Label tapes clearly and concisely at time of recording. Include copyright info on label.
- Break RECORD TAB on tape you want to protect from accidental erasure.
- Store tapes away from heat and direct sun light.
- Keep magnets away from tapes. Magnets will erase material on tape.
- Check NTS website for satellite information
If you decide later to RECORD over a tape that has been record protected, place a piece of tape over tab slot. Make sure tape cannot come off in machine and jam transport mechanism.
