1. GENERAL INFORMATION.
1.1.
DOWNLOADING CMB INFORMATION.
Description: This task covers downloading stored maintenance information from the CMB.
1.2.
General Information: A contact memory button (CMB) is a battery-free, read/write electronic data
storage device attached to selected components tracked by the DA Form 2410. The CMB
enhances configuration management, asset tracking, inspection and maintenance for the life of
the component to which it is attached.
Aviation Maintenance Automated Tracking System (AMATS) is an automated system that uses
CMBs to input part data into an existing maintenance management information system (MMIS).
Data stored on the CMB is retrieved either by the handheld PC using the Mini Fingertip Probe
attachment or by a laptop using a ButtonLink (Figure 1). Information is viewable and updateable
on site. The retrieved information is then inputted into the MMIS. Together, CMBs and an MMIS
create an automated maintenance environment. After maintenance is performed on an aircraft
component and the maintenance data is entered into the MMIS, the handheld PC or laptop is
used to read all of the component's new historical data and to then download the data to a new or
reusable CMB.
