Hi Richard, 
There could be several ways to go depending on if harmonized standards exist
for your device or not.  I will assume that at the time you had it tested
originally, they did not since you used Annex IV and not Annex III.
Somewhat relevant to this topic, we had used Annex IV on a radio device last
year(Harmonized standards did not exist), and this year with a new radio of
the very same type we were able to apply annex III(all of the standards were
harmonized recently.  Lucky me!).  Anyway, we have 2 of the same type
radios, one that carries a NB number and one that does not(You can imagine
the questions I get from our manufacturing folks).  The reason I bring this
up is, you could possibly convert to Annex III with the new model if the
standards that apply to it have been harmonized and draw up a DoC that
includes both models, if you feel no new testing is warranted.  If harmonize
standards still do not exist, then disregard all of the above and contact
your notified body.

Regarding your second question, yes I believe you need to Notify the
spectrum authorities of the new model and I have a story to tell on this
issue also.  Basically, we sell a radio to a customer of ours however they
wanted to give it there own model number.  I contacted my Notified Body and
for a small fee of course, they re-issued the statement of opinion including
the new variant and advised us(or the OEM) to notify all of the member
states of this new model.  They did nothing to the TCF which I found to be
interesting since that is the ultimate way to show compliance of a device.
I suppose the SoO(New Acronym for Statement of Opinion) is sufficient
enough.

Hope this helps.....

Subject: RTTE Notification



A radio product subject to the RTTE Directive was assessed by a Notified
Body under Annex IV, was notified to the national spectrum authorities and
is currently being marketed. Design changes are being made to the product
that do not affect the spectrum parameters, but the model number will be
changed to distinguish the two products. Is it necessary to communicate the
new model number to the Notified Body and/or the spectrum authorities?
