CARE AND MAINTENANCE
- DO NOT use MAGNETIZED tools when repairing or adjusting a disk drive.
- DO NOT place a disk drive near any device which generates "noise" e.g., -
motors, radios televisions.
- DO NOT stack drives upon each other or in any way inhibit air flow around the
unit. HEAT BUILD-UP can cause disk failures.
- Periodically CLEAN the read/write head with 90% isopropyl alcohol and a cotton
swab. CHECK load pad for excess wear. Clean or replace as necessary.
- Take the following precautions when handling a diskette:
- ALWAYS store a diskette in its jacket.
- Use ONLY felt-tip pens when writing on the label of a diskette.
- Do not bend or physically damage a diskette.
- Do not place a diskette in the area of a magnetic field.
- Do not attempt to clean a diskette.
- Do not touch the exposed area of a diskette.

DIAGNOSTIC and ADJUSTMENT procedures for the 2031 are outlined in detail in the Version 3.0 diagnostic
package (Commodore Part #31405201). This Kit contains a manual that outlines testing, adjustment and alignment
procedures and Version 3.0 and 3.5 diagnostic program disks.

The 2031 drive is shipped from the factory set for device # 8. The
channel may be hardware altered to device #9, 10 or 11. Channel
selection is changed on the main logic board by LIFTING the diodes at
locations CR 17/18 and/or CR 19. The following chart indicates the
selected device
| ADDRESS | LOW PROFILE | HIGH PROFILE |
|---|
| 9 | CR 19 | CR 19 |
| 10 | CR 17 | CR 18 |
| 11 | CR 19 & 17 | CR 19 & 18 |
The diode locations are indicated on the appropriate schematic.
