6.3 Installation of electronic cassette and Power supply adaptor
Loosen the mounting screws
and move the frame towards
the outside edge of a panel
Place a sheet of paper with a
description between the plates
and put them back in a panel
remembering that thin plate
should be placed at the casing
back side

is mounted supply from power network should be routed.
Electronic cassette casing is fixed to the base by means of two screws. Removal of
cassette casing requires disassembly of the whole cassette, because screws mount-
ing the casing are placed at the back of the plate.
Wire ends from feeding transformer should be wound on the smaller ferrite core
included in the set. Each wire should be wound 2.5 coils as shown on drawing 11.
Wire connecting the talking cassette with electronic cassette should be wound sim-
ilarly – at the side of electronic cassette the wire end should be wound on the
bigger core. If this is impossible due to the thickness of wire, insulation should be
removed and only those wires which are used for connection should be wound on
the core. Connect the wires according to connection diagram. If on the display
appears message [E-2] this means that there is a wire short circuit in entry phone
line. Entry phone CD-2502 is resistant to such short circuit, however, it should
be repaired as soon as possible. Electronic cassette is preliminarily adjusted and,
unless it is necessary, the position of control elements should not be changed.
In case of need the entry phone should be adjusted after the activation of all uni-
phones.
Then an installation procedure should be started P-3 (see p. 21) and an installation
and activation should be carried out.
Remove the frame by lifting
it slightly and then moving
towards the outside edge of
a panel
Dents on the frame left side
should be put in the openings
in a casing panel. The frame
should be pushed so that
screws are inserted in frame
openings
