(1) The amount of remuneration is determined by the extent to which the appliances and storage mediums are actually used as types for reproductions pursuant to section 53 (1) or (2) or sections 60a to 60f. Account is thereby to be taken of the extent to which technical protection measures pursuant to section 95a are used in respect of the works concerned.
(2) Remuneration in respect of appliances is to be set so as to be altogether equitable also in relation to the obligation to pay remuneration for storage mediums contained in such appliances or for other appliances or storage mediums functioning together with them.
(3) In determining the amount of remuneration, account is to be taken of such properties of the appliances and storage mediums as are relevant to use, in particular the capacity of appliances, the storage capacity of storage mediums and the extent to which they are rewritable.
(4) The remuneration may not have an inequitable effect on the manufacturers of appliances and storage mediums; its relationship to the price level of the appliance or of the storage medium must be economically equitable.
