It doesn't say it per se. However, it IS exclusionary.

Manueverng signals in the Rules are always prefaced
with the words 'when vessels are in sight' or some
version of those words. It follows that the signals
do not apply and should not be sounded when vessels
are NOT in sight or in or an area of restricted visibility
where such signals may be confusing to those vessels
not in sight of each other. This is only common sense
but if you need a Rule to make you happy here it is.

RULE 35
Sound Signals in Restricted Visibility

In or near an area of restricted visibility, whether by day
or night, the signals prescribed in this Rule shall be used
as follows:

Then it goes on to delineate the various signals and to
whom they apply. It follows that any and all signals
not described shall not be used 'in or near' areas
of restricted visibility just as any and all signals that
may confused may not be use in in-sight situations.

Sound and Light Signals
RULE 36
Signals to Attract Attention

If necessary to attract the attention of another vessel,
any vessel may make light or sound signals that cannot
be mistaken for any signal authorized elsewhere in these
Rules, (snipped rest about light signals

Therefore if a maneuvering signal might be confused as
a fog signal it may not be used 'in or near' areas of
restricted visibility.

Interesting - where does it say that?
