Just to add complications......
Some years ago, I was involved in WLAN development. When we went for Type Approval in the US, we failed - because the brand new laptop we were using did not meet the FCC Part 15 requirements on emissions. The (Japanese) laptop manufacturer didn't want to know either.
The moral? Even a so called 'Type Approved' equipment may fail dismally on emissions if you look at a production model.
In EMC (Electro Magnetic Compatability) work, you look at two things: Emissions and Immunity. Lack of immunity cannot be safely ignored by adopting the attitude of "I'm not going to repair my roof, so you have to stop it raining": similarly, emissions must be minimised, and in many cases, that can only be done by switching off. Especially when the manufacturers of such things as portable broadcast radios insist on minimal requirements so that they can keep the price down - and FM broadcast radios are well able to cause trouble to VHF Nav and comms.
