A system for obtaining, recording, displaying, storing, transmitting and
receiving maintenance and other information is provided. The system,
which may include an electronic maintenance apparatus that may be in the
form of a hand-held digital computer, allows a user to capture and store
images, sound, and/or error codes and related text or voice data and
other information concerning the system or object being maintained. The
information can be stored locally and/or transmitted to remote locations.
Retrieval of the images and other data at a later date provides an
historical perspective of the object, enabling one using the maintenance
apparatus to compare and contrast the condition of the object over time.
Instruction on how to accomplish a job at hand, diagnostic information
and/or support information may also be transmitted to and from the
maintenance apparatus.
