Section 14 – Maintenance and memory setups

Do not attempt to rewind or fast forward the cleaning tape, either in the DA-98 or in a video unit. Simply insert it into the DA-98 when you use it the next time.

If playing another tape seems to remove the errors, the problem is with the tape, otherwise you may want to clean the heads (see 14.1, “Head and trans- port cleaning”). Remember not to clean the heads more than 5 times in a row.

Excessive cleaning can cause excessive wear on the heads. Do not clean the heads too fre- quently, and never perform the head cleaning procedure more than 5 times running.

In addition to cleaning the heads, we recom- mend that you have the DA-98 checked by an authorized TASCAM service technician every 500 hours or so of use.

14.1.2 Checking error rates

If you hear noise and distortion on playback, even

after cleaning the heads, or if you are presented

with a tape of dubious quality, you may want to

You can ch ck

tions, edge and cente , for each of the two heads.

Block errors are shown by a solid block. It is inev- itable that there will be a few errors, but if the dis- play consists mainly of solid blocks while the tape is playing, something is wrong (and you will almost certainly be able to hear it!).

Use this display to show where the tape is in error, and which head is causing errors. In this way, you can pinpoint the cause of trouble.

NOTE

If, after trying different tapes and cleaning the heads, you still see many errors, you should contact a TAS- CAM service technician to check your DA-98.
