IBM Quick Reference Guide

About this manual

The guide begins with safety warnings for electrical hazards, advising users not to connect or disconnect cables during storms, to use grounded outlets, and to handle power and signal cords with one hand. It also includes specific cautions for modem installations and handling of lithium‑ion batteries, specifying the use of IBM Part Number 33F8354 or an equivalent replacement.

Later sections address laser‑based CD‑ROM/DVD‑ROM units, noting regulatory compliance and warning against opening the housings due to laser radiation risk. The document ends with a component identifier (25P4052) and printing information.
