ATTENTION
The unit is factory-wired for a nominal line voltage of 230
VAC (plug on PCB DX31, X5).
For exhibitions, follow point 4.1.
2. At nominal line voltage of 208 VAC
Swing out the door and unscrew the transformer cover.
Plug in the plug as shown for 208V (X6).
For exhibitions, follow point 4.1.
Reattach cover (two screws with washers) and close
the door.
3. Other nominal line voltages
For other voltages a matching transformer (autotrans-
former) with the following specifications is required:
•Input : nominal line voltage
•Output : 230 V
•Rating: 1 kVA continuous
•Max.voltage drop at 10 A ohmic load:≤6V.
Purchase a matching transformer which complies with
these specifications in the destination country.

Required Measuring Instruments
1. Digital multimeter Fluke 8000 A, Philips PM 2816 rms
or equivalent.
2. Electromechanical pulse counter KESSLER ELLIS, KT
203±1 pulse, or equivalent.
Radiation Protection
Observe the radiation protection guide lines as outlined in
the Operating Instructions manual.
X-radiation is emitted as long as the exposure key on the
Multitimer is depressed.
The X-ray indicator must light up on the Multitimer during
radiation. An acoustic signal must also be heard.
Line Voltage
Be sure the plug on PCB DX31 is plugged according to
nominal line voltage as outlined on page 10.
Power Supply Adequacy
To assure that the ORTHOPHOS system performance is in
accordance with Sirona specifications, an adequate power
supply is essential.
The Federal Performance Standard for diagnostic X-ray
units, code of Federal Regulations, title 21 CFR, subchap-
ter J, mandates an adequate power supply.

Multitimer
For measurements and controls the remote installed Multi-
timer must be connected directly to the unit's carriage
instead of the control cable's plug.
Duty Cycle
Between exposures maintain at least a cool-off time (auto-
matic exposure blocage, see Operating Instructions man-
ual).
Operating Instructions
During measurements and controls it is necessary to ener-
gize or de-energize the unit. For all operating steps please
refer to the Operating Instructions manual.
CAUTION with PC - Boards!
All PC-boards are fitted with electronic components sensi-
tive to electrostatic discharge (ESD). In an environment of
moving people electrostatic charges are unavoidable due to
friction of clothing, carpeting etc.
ATTENTION
To prevent damage of electronic chips do not touch same.
Always handle circuit boards by the edge of same.
ATTENTION

3. Connect measuring leads to terminal K1, Land N.
4. Plug in power cord and switch unit ON, see Operating
Instructions.
5. Press button Rat the Multitimer to return X-ray tube
head into the initial position.
6. Remove and reinsert the film cassette. The Ready LED
at the Multitimer must now go out.
7. Select P1 program and 90kV/8mA at the Multitimer.
