The ‘Baby-Comp’ is a device for ‘natural’ contraception. To determine the temperature, the measurement sensor is laid under the tongue for thirty seconds after waking. The computer then works out the best possible date for conceiving.
The first indication of pregnancy comes after five days, others follow after the fifteenth day. On confirmation of pregnancy after the eighteenth day, the expected date of delivery is automatically calculated.
The round appliance is beige and turquoise, with a turquoise cable. The display is located in the middle. The operation manual (which also applies to the Lady Computer) is separate.
