In principle only one person was needed to start the machine, however, several operators were useful.
Normally one switch had to be turned on to supply the machine with electricity.
Due to the use of transistors the development of heat was no problem, quite in contrast to the previously used electron tubes. The computer was developed for permanent operation, as no one knew how long the machine would need for long and complicated calculations. The "Mailüfterl" never caused any problem in permanent operation.
