good housekeeping habits. Keep the area clear of debris and clutter that can
hinder operations. Periodically check wires, cables, and other parts of the
system for obvious damage. Perform repairs or replace damaged parts as
required. Refer to the appropriate removal and replacement procedures, if
you need parts replacement guidance.
Follow the installation guidelines to avoid problems, such as stray magnetic
fields coming from nearby motors, copy machines, and similar devices. Y
