Abstract

In an arrangement for a security module that is plugged via an interface onto a base plate of a postal device, particularly a postage meter machine, the battery is replaceably arranged on the security module, and the voltage monitoring unit includes a circuit for a resettable self-holding, the self-holding being triggered when the battery voltage drops below a predetermined threshold. The status can be interrogated by a processor. The resetting of the self-holding can only be triggered when the battery voltage has risen above the predetermined threshold.
