This reminds of a situation that occurred many years ago where the US Air Force had a contract with a computer company to supply then with hundred of thousands of PCs. Because they were to be used by the military, they only had to meet the FCC Class A emissions requirements. The problem was that as old computers were replaced by newer faster computers, many of these old computers ended up in people's homes. As interference complaints stated coming into the FCC, a change in the status quo occurred and from that time on all PCs or any product that could be used in a residential environment had to be Class B even though it was not the intended initial use or market.
So whenever I see these kind of ambiguity regarding household and professional equipment, I wonder if the intent is to insure that a product likely to be used in a household meets all the desired requirements. It wasn't that many years ago it was assumed that any device with a network interface would never be used in a home. But today, many homes have networks. So, it would be difficult to identify something as "professional" when the definition of the type of devices used in a home is constantly changing.

It does mean that, and I don't think it's ambiguous in the case of consumer products 'adopted' for professional use. 'Professional' products NOT marketed for household use are not included, but the coupling of 'office' with 'household' in the text does create further uncertainty. First consider whether a 'stand-by' mode is really necessary. Also, provide a switch that really DOES turn everything off, including the charger for the battery-backed up clock.
