I have seen this more than once where there is a measurement such as "4-0.7". In this context, it clearly does not mean 4 to 0.7 mm so what does it mean. See the attached picture:

Not confident enough to make this a proper answer but my guess would be that it's just like the ±, just without the +; it's specified to be no larger than 4 mm, and no smaller than 3.3 mm.

@Hearth Nah, it just means 4 pads at 0.7 mm. The long dimension is 1 mm, so it cannot be anything else.

It looks to me that it means four 0.7 mm wide pads.
Another way of writing it would be 0.7 (4 places)

Yes. It has to be that, because the tolerances are given either by: $ 0,8 pm 0,1 $ or $ 0,05^0_-0,05$. Note the comma instead of the period :-)

If you look at page 3, top-left, there's a measurement that reads "4-0,45±0,05". I just wanted to mention that as it furthers your statement.

@EugeneSh.: The drawing shows the pads as 1 mm long and 3.7 mm apart vertically, so they can't be 4 mm wide, if the drawing is anywhere near drawn to scale.
