Setting jumpers. Set correctly contact JP1 in symmetrizator plate (see dwg. 8).
Value of selected resistance should correspond to wave impedance of used wire or
cable. Standard setting value 100 Ω corresponds to the impedance of UTP spiral
cables and telephone cables (e.g. YTKSY dia.
Set correctly contacts JP1 and JP2 in panel's electronic plate (see dwg. 9).

Mounting under the plaster. In the wall cut out an opening of the dimensions
that would enable to place the external panel freely in it and the frame should com-
pletely cover the opening edges. Then 4 holes 10 should be drilled for strut pins.
The tightening force (important when the cut out opening is deeper than cassette
depth) should be matched to avoid bending of a frame. Make electrical connections
and fix panel with a keyboard by two M4 screws and two rivets (included in the set).
If possible the external panel should be mounted inside wind shields; the panel is
better protected against weather conditions. Keyboard soiling (snow, mud) may re-
sult in its defective operation – in such cases the dirt should be immediately cleaned.
Mounting on the plaster. Drill openings for mounting the panel casing (mounted
on the plaster), place the frame (or frames) in the casing mounted under the plaster
and screw both elements by strut pins. Connect the wires and fix the panel with
keyboard by screws and rivets.
During the assembly of panels proper ventilation of sub-assemblies should ensured.
