1 Technical Description
1.1 Technical Data
ORTHOPHOS 3 Ceph has been inspected by the
VDE Testing and Certification Institute for compli-
ance with EN 60601-1, EN 60601-2-28 and EN
60601-1-3 and has been found to comply with these
regulations.
Original language German
This product is provided with a CE marking in
accordance with the regulations stated in the Directive
93/42/EEC of June 14, 1993 concerning medical
products.
Exposure times tele-exposure: 0,1 – 4,00s
Automatic Exposure Blockage: The duration of the exposure blockage (cool-off period)
depends on the kV/mA step set and the actually triggered
radiation time. Depending on the tube load, pause times up
to 200s are set automatically.
Example: For tele-exposure with exposure data 78kV/10mA
and exposure time 0.8s a cool-down time of 8s is observed.

4.1 Preparing the Tele-Exposure
Loading the Film Cassette
Treat film cassette and intensifying screens with care to
avoid scratching screen or denting the cassette housing.
Opening the cassette:
Push locks Ain direction of arrow.
Lift cover with tab B. Place film in cassette.
Closing the cassette:
Press cover down evenly until it locks into place.
1. Switching the Unit ON
The unit adjusts itself automatically.
2. Selecting the Ceph Function
by adjusting diaphragm No. 3 or 4.
No. 3, asymmetrical A, for lateral projection, or
No. 4, symmetrical S, for a.p., p.a. and carpus
exposures.
Adjust diaphragm:
by pressing locking button and turning diaphragm wheel
up to stop. The diaphragm number appears in the upper
right corner of the diaphragm.
The Cdisplay above son the Multitimer illuminates. The
kV/mA and s exposure parameters of the last
tele-exposure taken appear.
The LED above the Rkey on the Multitimer blinks.
3. Panorama Cassette Holder
Swing holder out of x-ray path (or remove image
receptor from the holder for panoramic radiographs).
Remove bite block. Close temple supports fully.
4. Move X-Ray Tube
into tele-exposure position by pressing one of the R
keys(4.).
The LED over return key R extinguishes.
The unit is ready for the tele-exposure.
ATTENTION
Should this LED go on blinking, call up the help massage
H3 to look for the reason.
Procedure see list of Help Massages H3 attached to the
unit.

For adjustment:
the swivel lock (21) has to be released first.
In addition to lateral projections also a.p. and p.a.
projections, carpus and other special exposures are
possible.
A = asymmetric, for lateral projections.
Diaphragm No 3 with soft-tissue filter
S = symmetric, for a.p., p.a., or carpus exposures.
Diaphragm No.4

•Special setting:
Adjust as required for attenuated or pronounced
recording of soft tissue.
For attenuated recording: set upwards
For pronounced recording: set downwards.
Selecting the tele-exposure data.
Briefly press one of the four program keys.
The LED above the key illuminates.
The corresponding programmed kV/mA values and
exposure time sare displayed.
Exposure data can be manually changed as follows:
Press key + or – until the desired kV or svalue is
displayed.
The LED over the patient symbol key does not light up in
this case.
The patient symbol keys are preprogrammed in the
factory with kV/mA and svalues.
