Abstract

An electric or electronic module provides an error indication through a display unit. The display unit indicates power failure to the module in addition to an error indication. Power failure to the display unit results in power failure to an operationally essential component of the apparatus in which the module is installed, thereby providing a secondary power-fail indicator.
