1 CONDITIONS OF OPERATION
NOTE!
Entry phone CD-2502 is available in two versions: audio and video. In both versions
the same electronic cassette EC-2502 and power supply adapters are used, in both
versions parameters are set in the same way. The two versions differ mainly with
the types of used panels, additional elements in video version (panels in video ver-
sion, switches, distributors and monitors) and the method of performance of power
system. Both versions of entry system are described in the instruction. In case of
installation and activation of audio version one should disregard recommendations
referring to video version.
In entry phone CD-2502 one type of electronic cassette is used - EC-2502. The use
of the device (main or subordinate entrance) is defined by program.
In the description abbreviations are used — exchange configured for the service of
the main entrance is designated EC-2502/H and exchange for the service of subor-
dinate entrance EC-2502/U. Cassettes are default configured as EC-2502/U.
1 Conditions of operation
 Prior to the installation and use of an entry phone one should get acquainted
with the installation and operation instruction.
 Wiring system should be performed according to standard PN-IEC-60364-1 by
an authorized person. It should be made in such a way as to avoid the risk of
lightning.
 Monitor should be mounted in a place that is easily accessible for users at
a height of min. 1.5 m, in such a way as to eliminate the danger for the
users and accidental jostling. Monitor should be installed at a distance of min.
1.5 m from the sources of strong electromagnetic interferences — transformer
feeders, magnets, metal sewage and gas pipes because it can result in picture
distortion.
 It is forbidden to connect the entry phone elements to installations other than
made according to the recommendation of an entry phone producer.
 Monitor, uniphone and electronic cassette should not be exposed to high tem-
perature or humidity. These elements should not be installed in bathrooms or
close to heaters.
 Openings in a monitor and uniphone should not be covered because it can result
in their improper operation.
 No metal objects can be put into the openings in uniphones or monitors because
this can cause electric shock or fire.
 El. supply from external supply sources should not be connected to uniphone
terminals because it can cause its damage or fire.
3

2 INSTALLATION OF ENTRY PHONE
 It is forbidden to hold the receiver near an ear and push the lever (hook-
switch) in the uniphone/monitor base at the same time or hold the
receiver near an ear while the lever (hook-switch) is pushed because
this may cause a loud call signal in a receiver that can result in hearing
defect.
 It is forbidden to repair the entry phone equipment by unauthorized persons
because it may cause a threat to health and life.
 El. supply from sources of parameters other than recommended by a producer
should not be connected to uniphone terminals. Producer will not bear respon-
sibility for losses resulting from the use of improper feeders.
 Neither petroleum nor any solvents or strong detergents can be used for the
cleaning of entry phone elements because they may cause damage of the equip-
ment surface.
 Picture distortion appearing during rain or right after raining is transient and
connected with collection of water in the area of lens and is not the sign of
equipment defect.
 Signals from entry phones should not be sent to RTV sets because his may
result in the damage of such sets or entry phone.
 Outside panels should not be sealed with e.g. silicone because it worsens
ventilation and leads to corrosion.
2 Installation of entry phone
The following items include the most important stages of design, performance
and activation of an entry phone system. Item numbers in instruction containing
the detailed information are given in brackets.
 Get acquainted with the operation instructions especially with the entry phone
conditions of use.
 Define the final configuration, operation mode and then select the necessary

3 ELEMENTS OF ENTRY PHONE
 In case the system of entrance hierarchy is activated, set the range limits for the
apartments in cassettes operating as EC-2502/U (for subordinate entrances).
Leaving default settings in these cassettes may cause wrong operation of the
entry phone system.
 In case of need tune the acoustic path.
 Check the operation of the system using the installation procedure.
3 Elements of entry phone
Electronic cassette
In entry phone CD-2502 one type of electronic cassette is used — EC–2502 for main
or subordinate entrances. Its operation mode is defined by an installing specialist.
The cassette operates in default setting in U mode and is used for subordinate
entrance. Service of the main entrance (operation in mode H) requires the change
of cassette configuration (see programming, page 28).
External panel
For CD-2502 system a few types of external panels were designer. Panels are
produced in audio and video version (with colour camera and LED lighting). They
are made of zinc coated sheet covered with powder paint or of stainless steel; in all
panel optical keyboard is used. Panels may be equipped with an iButton electronic
touch key reader or RFID proximity key reader. Electronic key is an alternative to
a combination lock, it is also a very good replacement of a traditional mechanic key
because it is lighter and more comfortable in use. Furthermore, an electronic key
may be easily programmed in any number of entry phones equipped with readers.
The following external panels are available:

3 ELEMENTS OF ENTRY PHONE
Illuminator in panels in version video makes it possible to recognize the face at
a distance of approx. 50 cm from the video camera. Lighting diodes are placed be-
hind the display, so they are effective only if the face of a visiting person is directed
towards the entry phone keyboard.
Inside the external panel there is a photoelement which reacts on light. When the
external illumination is good enough, the illumination of keyboard and camera are
turn off.
In CD-2502 system to one electronic cassette only one external panel can be con-
nected.
Uniphones
Uniphones for digital Laskomex entry phones co-operate with digital entry phone
system CD-2502. They are models: LF–8, LT–8, LX–8, LR–8 or LM–8 in all vari-
eties.
It is allowed to use the uniphones produced by other manufacturer, pro-
vided that the impedance of uniphone (during the call and conversation)
Z≥40 Ωand the line current in the active state I=(70-100mA).
The use of uniphones not made by Laskomex may be associated with the
invalid operation of entry phone system. Laskomex does not take the re-
sponsibility for damage caused by equipment made by other manufacturers
and may refuse to perform warranty repair of any damage or injury in entry
phone system caused by using uniphones not made by PPUH Laskomex
or not accredited by it.
Uniphone LM–8W/1 has an additional switch to control the gateway drive. The
use of uniphones of other producers is not recommended because it may cause the
wrong operation of the whole entry phone system.
Uniphone LM–8W/3 is equipped with a highly effective receiver which ensures
call signal louder by approx. 6 dB than in standard LM-8 uniphone.
Uniphone LM–8W/4 has a door-bell function. Additional terminals in the uni-
phone enable the connection of bell button. Pressing the button results in switching
on the gong. Uniphone requires additional supply.
Loud speaking Uniphone LG-8 and LG-8D
Uniphone LG-8 is intended for digital entry phone systems produced by Laskomex
(CD-2502 and CD-3100). Uniphone LG-8 operates in simplex system — during the
conversation the user must press TALK pushbutton when he is speaking. Uniphone
LG-8D operates in duplex system (conversation is possible in both directions without
activating buttons or switches). Uniphone requires external supply from central
feeder 15 V DC/ 4 A (up to 40 uniphones) or own feeder 15 V DC/1A . Uniphone
functions also as a door-bell. Bell button is connected to two terminals in uniphone
and its pressing results in generating gong signal in uniphone. Detailed information
on connection, programming and use of uniphone LG-8 is included in the instruction

enclosed to it.
Monitor MVC–6550 and 6650
Colour monitors for Laskomex digital systems. They are loud speaking monitors
without receivers with TFT display operating in duplex system. Detailed information
on monitor assembly and use are included in the instruction enclosed to them.
Signal distributor CVR-1 and CVR-2.
Vision signal distributor is intended for the entry phone in video version. It en-
ables connecting the monitors to entry phone installation or branching the electrical
installation of entry phone. Furthermore, distributor amplifies vision signal.
Electric system, which connects electronic cassette with monitors, is made in form
of bus-bar with distributors CVR-x on the floors. Wires from monitors should be
routed to the distributors. The installation method is important - wire should be
routed from one distributor to the next one and in the distributor at the end of
bus-bar the line load should be configured properly (see dwg 14, page 23).
Signal distributor has one input of signals L+,L-,C+,C- with screw terminals (ARK)
and four independent outputs with sockets RJ45 (CVR-1) or ARK (CVR-2).
Distributor CVR-1 does not require power supply adaptor – it is supplied from mon-
itors connected to it, although it has clamps enabling supplying it from other source
e.g. electronic cassette EC-2502. It is used when the distributor operates as signal
adapter.
Distributor CVR-2 require external power supply adaptor, which can be also used
to supply monitors.
In the distributor there is an amplifying and correction system of video signal al-
lowing optimal adjustment of distributor parameters to the parameters of electrical
system.
Video signal change-over switch CVP-1 and CVP-2
Change-over switch CVP-x is used for the selection of the source of video signal
displayed on the monitor screen of entry phone CD-2502 in video version, operating
in a system with main entrance. Switching-over is made between a signal from the
video camera in external panel at the main entrance and a signal from the video
camera in external panel at the subordinate entrance (staircase). In CVP-2 switch
there are 2 additional inputs (can be connected signals from additional cameras)
where video signal is switched between them - a total of 4 video signal inputs.
The switch has 2 outputs X and Y, which can be used for branching the signal
installation. If there is need to distribute the signal to a larger number of branches,
then signal distributor CVR-x should be used. Change-over switch CVP-x should
be mounted at each subordinate entrance possibly close to electronic cassette and
power supply adapter.

3 ELEMENTS OF ENTRY PHONE
Power supply
Ac power supply adapter ZS-K-25/01 art.0018 or TSZZM 25/021M should be
used for supplying electronic cassette.
Electro-catch or electromagnetic lock
Entry phone CD-2502 can control electro-catch or electromagnetic lock. Op-
eration time is programmed and can be changed by an installing specialist. It is
recommended to use electro-catches for voltage 12V AC/DC and power consump-
tion not exceeding 1A. Default control of electro-catch by run of 50 Hz frequency
with characteristic buzzing of electro-catch.
Electromagnetic lock should be supplied by voltage 12 V DC/1A. In order to use
the electromagnetic lock, contact ZT1 in electronic cassette should be switched to
‘ELECTROMAGNETIC LOCK‘ position. It is also necessary to set the frequency of
voltage run supplying the lock on ‘0‘, because supplying the lock with alternating
voltage makes that the door blocking force is considerably weaker. Jumper should
be put on contact J3. It is intended to liquidate residual magnetism which can
hamper opening of door.
Demagnetization system should be absolutely switched off during the op-
eration with electro-catch.
Reverse electro-catches work on the similar principle. They keep door blocked as
long as voltage is supplied to them. Using reverse electro-catch requires configura-
tion of entry phone for operation with electromagnetic lock.
Door opening pushbutton.
Pushbutton is used for unblocking the electro-catch or electromagnetic lock when
leaving the building. Any short circuit pushbutton can be used – e.g. bell or attack
pushbutton used in alarm systems; signaling diode can be connected as well.
Additional call module PW-1
The module enables an additional call signal (acoustic or optical) in the uniphone.
It is used in a situation when a uniphone is installed in a room of high noise level or
there are partially deaf people in a room. It enables - during calling - the activation
of any equipment supplied by voltage 12...24 V AC - bell, siren or signaling lamp.
External panel casing
As a standard external panels and lists of occupants are delivered in a frame
mounted under plaster, casings enable their mounting on plaster.

Accumulator
An accumulator can be connected to electronic cassette which is used for sup-
plying entry phone in case of loss of voltage in power network. It is recommended
to use accumulators 12V/7Ah. Electronic cassette is equipped with an accumulator
loading system and protection against complete accumulator unloading. Emergency
loading time depends on the capacity of accumulator and intensity of entry phone
use and is from a few to several hours.
4 Numbering modes
Digital entry phone as a standard can operate numbers within a range 1...255,
however, very often it is necessary to operate higher numbers or numbers of con-
siderably wider range. This is possible owing to different numbering modes.
4.1 Normal mode
In normal mode physical number of uniphone (programmed by jumpers) corre-
sponds to logical number (selected from the keyboard of talking cassette). This is
a default mode of operation of entry phone exchange.
4.2 Numbering mode with range shift
In this numbering mode physical number of a uniphone (programmed by jumpers)
differs from its logical number (under which a uniphone rings after having selected
9

4.3 Hotel numbering mode 4 NUMBERING MODES
the number from the keyboard). This numbering mode is used for apartments of
numbers higher than 255.
logical number = physical number + range shift
This numbering mode is switched on in a moment of setting of parameter value
‘range shift‘ to the value higher than ‘0‘.
Example:
In a building an entry phone should be used for apartments Nos. 301...310.
 In uniphones physical numbers should be programmed as follows: in apartment
301 number 1, in apartment 302 number 2 etc.
 Then cassette programming mode should be entered (see item 8, page 27) and
the parameter of range shift should be set to value 300.
After having done this and selecting from a keyboard number 301 the uniphone in
which number 1 has been programmed will ring, after having selected number 302
uniphone with number 2 will ring etc.
4.3 Hotel numbering mode
This numbering mode is meant for the buildings in which room number starts
with a digit defining number of floor on which the room is located (hotels, resort
houses, dormitories etc.). Physical number of a uniphone is calculated according to
the formula:
Physical number = P * LL + XX (A)
where P - floor number, LL - amount of rooms on one floor (value of parameter
[LPi]) - see dwg. 30), XX - number of room on the floor – number from the range
1 ... [LPi]
This numbering mode will be activated at the moment of setting the value of
parameter [LPi] ”amount of rooms on a floor” to value higher than zero.
Example: An entry phone should be mounted in a five-storied building in which
the numbering system is as follows: on the ground floor 1 . . . 20, on the first floor
101 . . . 102 etc. There are 20 rooms on the ground floor. On next floors, after
taking into account full hundred numbers which are also taken into consideration
in calculations (100, 200, 300...) we get 21 numbers for each floor. First of all
the cassette programming mode should be entered and parameter [LPi] (amount
of rooms on the floor) should be set to value 21. After quitting the programming
mode the exchange operates in hotel numbering mode.
Then it should be defined which logical numbers will correspond to individual phys-
ical numbers of uniphones. To do this a formula or a calculator available in one
10

4.4 Mode with building numbering 4 NUMBERING MODES
of entry phone programming procedures in the exchange can be used (P-3-5, P-3-6).
numbers of rooms 1... 20 uniphone number 1, 2, ..20 ground floor
numbers of rooms 101...120 uniphone number 21, 22,...41 I floor
numbers of rooms 201...220 uniphone number 42, 42,...62 II floor
............. ......... ............. ............. ........
numbers of rooms 601...620 uniphone number 125, 126,...146 VI floor
Finally uniphones should be programmed to the numbers settled before.
Total number of uniphones used in this numbering mode should not exceed 255.
4.4 Mode with building numbering
This numbering mode can be used only in entry phone system with entrance
hierarchy. In order to get connection with an apartment from an external panel at
the main entrance one should first of all select building number and then apartment
number. This numbering mode allows repeating apartment numbers in different
buildings. The following operations should be made in order to activate this mode:
 In electronic cassette for subordinate entrance set parameter [nbL] (block num-
ber) in procedure P-1 to value higher then zero. (see page 30). To get con-
nection with any apartment in this staircase the apartment number should be
preceded by set number.
 The operation should be repeated for other staircases (buildings). Values [nbL]
can be repeated in subordinate systems provided that these systems operate
with other logical numbers of uniphones.
 In electronic cassette for main entrance set the value of parameter [NbL] in
procedure P-2 to 1 (see page 32).
4.5 Range of operated numbers
In numbers entry phone the range of operated numbers can be limited. (see page
30). In default setting the operation of all apartment numbers is included. If the
range is limited, selection of a number outside the set range will result in displayed
message [OFF].
Limiting is set for physical not logical numbers!
Limiting of the range should be set especially in electronic cassettes for subor-
dinate entrances (multi-entrance system with entrance hierarchy) because leaving
default range setting may hamper using or make impossible the activation of the
whole entry phone system.
Default set range 1...240.

4.6 Additional numbers 5 CONFIGURATIONS OF ENTRY PHONE OPERATION
4.6 Additional numbers
In many cases it is necessary to operate numbers which do not belong to the
operated range. In entry phone CD-2502 these numbers can be associated with
fourteen physical numbers: 241...254 (parameter Unin procedure P-1). For each
of the mentioned numbers it is possible to set individually any number from the
range 1...9998.
4.7 Directing the numbers that are not serviced
In entry phone CD-2502 all numbers which are not operated by entry phone
CD-2502 can be directed to one selected number. Owing to this entry phone
CD-2502 can be used in a single-family home – entry phone can be configured in
such a way that any number selected by the keyboard will result in entry phone
ringing at one selected number.
5 Configurations of entry phone operation
5.1 Basic system
In basic version the entry phone operates for one staircase or building with one
entrance. The system consists of electronic cassette EC-2502 working in U mode,
external panel, feeder and from 1 to 255 uniphones. External panel should be
mounted at a distance not exceeding 15 m from the cassette. Basic system can be
used for staircases in apartment houses, tenement houses, companies etc. to which
there is only one entrance.
5.2 System with entrance hierarchy
In a system with entrance hierarchy there are two types of entrances: the main
entrance and subordinate entrances. System CD-2502 can operate for one main
entrance and max. 64 subordinate entrances. From the main entrance a connection
can be made with each apartment in any building or staircase serviced by the entry
phone system. Using panels at the entrance to staircase (subordinate entrance)
a connection can be made with the apartments located in this staircase only. Entry
phones at subordinate entrances can be used independently.
During the conversation held between the main entrance and an apartment located
in one of the staircases the whole line in this staircase is busy and a message ZAJ
will be displayed on the outside panel display at the entrance to this staircase. In
order to use the combination lock or get the connection with any apartment one
should wait till the conversation from the main entrance is finished. If during the
conversation held from the subordinate entrance in one of the buildings (staircases)
there will be made an attempt of connection from the main entrance with any apart-
ment in this building (staircase), the conversation started earlier will be interrupted

6 Installation and activation of entry phone
6.1 Performance of wiring system
Entry phone CD-2502 is available in audio and video version. Performance of
wiring system depends on the version of entry phone.
General recommendations on performance of wiring system
 Electrical system should be made according to standard PN-IEC 60364-1 by
a person authorized to make such installations.
 Wire cross section depends on the distance between the elements that are
connected (see chapter ”Selection of wires”, page 58). In order to ensure
proper cross section the selected connections can be doubled or wires of larger
diameters can be used.
14

6.1 Performance of wiring system 6 INSTALLATION AND ACTIVATION
 In installations with the main entrance operation mode is set in electronic
cassette. Depending on the selection they can function as cassettes servicing
the main entrance (EC-2502/H) or subordinate entrance (EC-2502/U). Default
setting of the cassette is configured to operate with the subordinate entrance.
 It is recommended that electronic cassette, power supply adapter and CVP-1
switch be placed possibly close to one another e.g. in an installation box.
Power supply adaptor should be installed at such a distance as to enable its
connection by means of an original cable.
 Total distance between electronic cassette and uniphone (monitor) should not
exceed 150m.
 It is recommended to route all cables as away as possible from other installa-
tions. The cables of entry phone system should be routed at a distance not
smaller than 20 cm from power cables.
Wiring system of entry phone in audio version
 Section between external panel and electronic cassette should not exceed 15 m.
Spiral wire of dia. min. 0.5 mm should be used. Minimal number of entry phone
wires amounts 16 for entry phone without gateway drive control and 18 with
gateway control.
 Number of wires can be limited if door opening button and list of occupants
are not used in the entry phone.
 For the connection of electronic cassette with external panel spiral wire should
be used. For routing in the earth, wire protected against moisture should be
used. Wires YTDY, YTKSY, UTP, LAN T11 or similar are recommended.
 During wire connection a special attention should be paid to correct pairing of
connections. On the diagrams spiral wire is marked with thick and thin line
with grey filling between them.
 In a multi-entrance system an electronic cassette at the main entrance
(EC-2502/H) should be connected with all electronic cassettes at the sub-
ordinate entrances (EC-2502/U). A spiral min. two wires should be used (at
gate control two additional wires should be reserved).
 Connection between electronic cassette and uniphones should be made by
means of any double wire e.g. YTDY. In case of gate control min. 4 wire
conductor should be used.
 In audio version the routing of wiring system from electronic cassette to uni-
phones does not make any difference. Each uniphone can be connected by
a separate wire, wiring can be router from one uniphone to the next one or
uniphones can be connected on a common bus-bar. The distance between
15

a uniphone and an electronic cassette should not exceed 150m for wire dia.
0.5 mm. This distance can be extended by increasing the cross-section of
connecting wires.

Wiring system of entry phone in video version
 Section between external panel and electronic cassette should not exceed 15 m.
Spiral wire of dia. min. 0.5 mm and impedance 100, 124 or 136 Ωshould be
used. Minimal number of entry phone wires amounts 18 for entry phone without
gateway drive control and 20 with gateway control.
 Number of wires can be limited if door opening button and list of occupants
are not used in the entry phone.
 For the connection of electronic cassette with external panel spiral wire should
be used. For routing in the earth, wire protected against moisture should be
used. Wires YTDY, YTKSY, UTP, LAN T11 or similar are recommended.
 During wire connection a special attention should be paid to correct pairing of
connections. On the diagrams a spiral pair is marked with thick and thin line
with grey filling between them.
 In a multi-entrance system an electronic cassette at the main entrance
(EC-2502/H) should be connected with all electronic cassettes at the sub-
ordinate entrances (EC-2502/U). A spiral with min. two wires should be used
(at gate control two additional wires should be reserved).
 Connection between electronic cassette and uniphones should be made by
means of any double wire e.g. YTDY. In case of gate control min. 4 wire
conductor should be used.
 Signal video in CD-2502 system is sent by symmetrical line. Such solution
ensures low susceptibility of line to external interferences and enables sending
picture at relatively long distances, however it requires observing the regulations
during the performance of wiring system.
16

6.1 Performance of wiring system 6 INSTALLATION AND ACTIVATION
 It is forbidden to make wire branching (e.g. in junction boxes). Wire should be
routed from one receiver (monitor, distributor, switch) to the next one. A rule
should be obeyed that signal sent to the receiver by one wire and goes out by
the other. Both wires are connected on receiver terminals.
 Wiring system at the section between electronic cassette and monitors should
be made in form of bus-bar with distributors CVR-x. To one distributor 4
monitors should be connected.
 Section between electronic cassette and distributors should be made using spiral
UTP cat.5 or telecommunication spiral (e.g. YTKSY).
 Section between distributor and monitors should be made using spiral UTP
cat.5. In case of CVR-1 plugs RJ45 should be installed on wire ends at the
distributors (according to the instruction).
 Total length of a segment electronic cassette – distributor + distributor –
monitor should not exceed 150m.
 In entry phones with many occupants a wiring system should be made in form
of a branch. In one branch up to 10 receivers (monitors or distributors) can be
connected. The next branch can be made by treating one of the outputs from
any distributor as a beginning of a branch.
 An attention should be paid to the adjustment of wire wave impedance to the
impedance of the connected equipment. In equipment installed at the beginning
and at the end of the line a resistor should be installed in parallel to the line
of value equal to cable wave impedance. In other equipment connected to the
line no load resistors should be installed. Load resistance in external panel,
monitors, distributors and switches is set by jumpers.
 Mixed systems, in which uniphones and monitors are used at the same time,
are allowed.

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 Ωcorresponds to the impedance of UTP spiral
cables and telephone cables (e.g. YTKSY dia. 0,5).
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.
That is why sealing (with silicone, foam, etc.) of space between frame and panel

Installation of a panel with the list of occupants Panel with the list of occu-
pants CP-2502N cannot be equipped with video camera so it is not used in entry
phones in video version.
When installing a cassette with a list of occupants one must remember to place
a description prior to placing the rivets. The description should be made on a piece
of paper of dimensions 51 x 90 mm. It is best to make a print on A4 sheet of paper
and then it should be cut to get the required size. 4 mm margin should be left at
each edge of the sheet. Print should be made on a white sheet of paper of basis
weight approx. 100 g/m2 using a laser printer. Ink printer should not be used for
this purpose because the print may be smeared due to moisture. That is why it is
recommended to laminate the sheet with a printed list. Any graphic program may
be used for making the print e.g. Corel Draw or Photoshop.
In video version lists of occupants are not available.
6.3 Installation of electronic cassette and Power supply adaptor
Electronic cassette and power supply adaptor should be mounted inside the build-
ing, most preferably in a place which is not accessible for unauthorized persons. It is
recommended to place both devices in an installation box, the cassette is mounted
by means of 4 screws or on a rail DIN. To the place where the power supply adapter
