Care and Maintenance
Head Demagnetizer | |
| (U.S.only) |
Even though the heads used in your 424 MKIII have high wear resistance and are rigidly constructed, performance degradation or electro- mechanical failure can be prevented if maintenance is performed regularly.
CLEANING
The first things you will need for maintenance are not expensive. The whole kit with the swabs and fluids you will need for months will cost less than a couple of high quality cassettes.
We cannot stress the importance of cleaning too much. Clean up before each session. Clean up after every session. Clean up every time you take a break in the middle of a session.
DEGAUSSING (DEMAGNETIZING)
A little stray magnetism can become quite a big nuisance in tape recording. It only takes a small amount (0.2 Gauss) to cause trouble on the record head. Playing 10 cassettes will put about that much charge on the heads. A little more than that (0.7 Gauss) will start to erase high frequency signals on previously recorded tapes. You can see that it's worth taking the trouble to degauss regularly.
A clean and properly demagnetized tape recorder will maintain its performance without any other attention for quite a while. It won't ruin previously recorded material, nor will getting it back to original specifications be difficult.
Cleaning the Heads and Tape Guides
All heads and metal parts in the tape path must be cleaned after every 6 hours of operation, or before starting and after ending a recording session.
1.Open the cassette compartment door. Tape should not be loaded.
2.Hold STOP and REHEARSAL and press POWER to activate a Cleaning mode. "Cleaning" will show on the display.
CLEANING MODE : While in this mode, PLAY, F.FWD, REW, and STOP are effective, letting you get access to the head block, and rotate the capstan shaft and the pinch roller at high speed in either direction, or at normal play speed, making it easy to clean them as you perform the following steps.
3.Press PLAY (needless to hold it this time), so the head blocks move out.
·If you leave the unit in Cleaning mode for 3 minutes after you have pressed PLAY, it will automatically go to STOP, the head block moving back.
4.Using a good head cleaning fluid and a cotton swab, clean the heads and tape guides until the swab comes off clean. Wipe off any excess cleaning fluid with a dry swab.
