RRD42 CDROM Disc Drive Owners Manual

This document is the RRD42 Disc Drive Owner's Manual, published by Digital Equipment Corporation in February 1991.

Key Information:

• Product Description: The RRD42 is a half-height, 5.25-inch, 600-megabyte compact disc storage device compatible with Digital systems. It supports audio playback (hardware-enabled, OS support dependent) and uses the SCSI-2 bus, suitable for various computer systems. It comes in two versions: tabletop and embedded.
• Installation: The manual provides general installation procedures, including connecting SCSI and power cables, and setting the SCSI ID. For the embedded drive, it highlights the critical "Mode Select Jumper" which determines the block size (512 bytes for VMS/ULTRIX; 2KB for MS-DOS/SCO UNIX). It also covers post-installation verification using a power-on self-test (POST).
• Operation: It details the functions of the drive's front panel controls (headphone jack, eject button, busy indicator) and rear panel connectors. Instructions are provided for handling discs and caddies, including how to open a caddy and load a disc into it. The general operating procedure involves inserting the loaded caddy, after which the drive reads the Table of Contents.
• Safety and Compliance: The document includes significant safety warnings, emphasizing that the unit should not be opened due to fire, electrical shock, and internal laser radiation hazards (Class 1 laser product). Servicing is strictly for qualified personnel. It specifies the mandatory use of a particular shielded power cord (part number 17-03040-01) for USA/Canada to comply with FCC Class B limits and advises on reducing radio/TV interference. It also includes German (DBP) and Canadian (CSA) regulatory notices and provides specific laser characteristics.
• Audience: It is intended for the owner of the RRD42 disc drive, requiring no prior prerequisites.
• Structure: The manual is organized into chapters covering product description, generic installation, usage, problem-solving, preventive maintenance, and specifications.
