A power reset module may reset an automatic shut-off module of a target device by momentarily disrupting power to the automatic shut-off module at a determined interval and automatically restoring power after a time period of up to two minutes. In multiple embodiments, the power reset module comprises an activation switch with an activation switch output coupled to a frequency module. The frequency module may output a frequency module signal on a determined interval via a frequency module output coupled with a reset module. The reset module momentarily transitions a reset switch to a reset state periodically at the determined interval for up to two minutes prior to automatically transitioning the reset switch to a non-reset state. Transitioning the reset switch to the reset state disrupts power to the automatic shut-off module and automatically transitioning the reset switch from the reset state to a non-reset state restores power to the automatic shut-off module thus resetting a state of the automatic shut-off module. In several embodiments, a cash register incorporates a programmable power reset device for disrupting and restoring power to an automatic shutoff circuit to reset the automatic shutoff circuit allowing a user to access the cash register.
