To retrofit such a meter with an additional communication interface the calculator´s adhesive seal has to be destroyed and the
device´s calculator to be opened. Use a screwdriver with a wide tip (4 - 5 mm) and carefully press in the two round
predetermined breaking points above the cable feedthroughs (see picture 1).
Then insert the screwdriver into one of the two openings at an angle of approx. 45° and carefully lift the handle up to approx.
90° (see picture 2). The upper housing piece of the calculator is then no longer latched on this side. Repeat this with the other
opening. Now the upper housing piece can be taken off.
