Hi Tregers, I'll like to join the club and offer my 2 cents too.
Secure telephone is subject to EN 55022:1995 for the emissions and EN 50081-2:1993 or EN 50082-2:1995 subject to the product's primary environment of use, either residential or heavy industry. It is up to you to decide on targeted market, product functionality, price, etc. EN 55022 Class A goes with EN 50082-2 for (heavy) industrial and EN 55022 Class B and EN 50082-1 for residential environment. Emissions to EN 55022 Class B (residential) and immunity to EN 50082-2 (heavy industrial) will provide unrestrictred sale and use. Your product has to comply either to more stringent emission or to more stringent imunity specs if it will be used in one of the two identified areas. Additional decision making factor in this case of secure telephone set is telecom approval authority which may make a choise for you. My suggestion would be to meet Class B and EN 50082-2. If you think that will not be acceptable, decide in which environment your product will be typically used, prepare supportive evidence and work with telecom approval authority before you actually submit telephone for approval.

If you've any dreams of getting your product into a residential environment, CISPR11 Class B is the best way to go. Shooting for the more stringent emissions requirement helps in the long run, too, when you'll probably start swapping components out to keep costs down. If the product barely meets the Class A limits as is, then your application will be met with all kinds of questions, especially if it's your first time at bat with your Notified Body. Even though the CE Mark is MANDATORY, certain clauses of the immunity testing (EN50082) may not be required, they vary from product to product. For something small, the tests are usually not a huge undertaking. You should consult your notified body & inform them of what you've got. They will give you the straight story on what tests are required. bon voyage, Len >I am new at this so please bear with me. I have two questions: > >1.
