An electronic control device for interfering with locomotion by a human or animal target includes a processor and stimulus signal generator. Upon engagement of a trigger by an operator, a stimulus signal is provided to electrodes for a time period to interfere with the skeletal muscles of the target. An indication is provided to the operator corresponding to the time period to alert the operator before deactivation of the stimulus signal. In response to the alert, the operator may reengage the trigger to continue or resume the stimulus signal.
