1.1 Important Notes

• The ORTHOPHOS® Plus DS / Plus DS Ceph / 5 / Plus / Plus Ceph operates with the following nominal line voltages: 208 V, 230 V, 50/60 Hz. The permissible line voltage fluctuations The internal line resistance

• Remote control The unit can be equipped with a remote control inside the treatment room or outside an X-ray room. For the tests the Multitimer can/must be removed from the remote control module and is to be connected directly to the

unit (for remote control with the Multitimer without coiled cable, the coiled cable has to be connected for the tests according to the installation instructions).

Remember that the fault can then be in the deactivated cable.

• Warm-up time, self-adjustment, cool-down time, After power-up the unit always requires a warm-up time of one minute.

During this time, the self-adjustment routine for the mechanical elements and electronics of the unit is executed. Pressing a key during the self-adjustment causes an error indication at the Multitimer and on the lateral operating panel. The cooldown time between two consecutive exposures is ensured by the automatic exposure blockage determined by the pulse/ pause ratio. The count down of the waiting time required is indicated on the Multitimer. The turn-off time of board XABOP must be at least 60s; otherwise the unit will not function correctly (no exposure readiness).

• For demonstration units Now, no X-ray radiation is generated. Upon completion of the self-adjustment S.88 is indicated on the Multitimer → the forehead support has reached position 10.00.

• The overall software version Multitimer D4 as well as the version number of the memory card. Refer to the list of software versions. When switching the unit ON the versions are indicated on the Multitimer for about three seconds after the segment test.

• Interference of radio telephones with electromedical equipment The use of mobile telephones in the area of the medical practice or clinic is prohibited in order to ensure the

operational reliability and safety of electromedical equipment.

• Disposal The X-ray tube assembly contains a tube which can implode, a small amount of beryllium, a lead lining and some mineral

oil.

• Removal of the unit Prior to the disassembly and removal of the unit the transport safety screw must be screwed into the vertical column (see Installation Instructions).

• Error messages Error messages are indicated on the Multitimer and on the lateral control panel.

• Help messages H if radiographic readiness is not reached Help messages are displayed on the Multitimer and on the lateral control panel.

1.1 Important Notes

• If you have to remove panels from the unit. Refer to section "Removing panels". With the panels removed, remember that incident direct sunshine or bright room light can cause unit malfunctions by ac-

tivating the light barriers.

Therefore: Avoid direct sunshine and bright lighting above the unit

NOTE: For ORTHOPHOS Plus DS TSA, take TSA image receptor out of side holder before removing the panels.

Remember when reattaching the panels: Secure sheet metal covers with screws.

IMPORTANT: For reasons of EMC it is essential Reinstall all panels.

• Do not move the secondary diaphragm by hand or subject it to any stress when removing from the package.

• Measurements Before connecting a measuring instrument, always switch the unit OFF. Select the required current/voltage type and set the measuring range according to the expected value. Carry out continuity tests only with the unit switched off.

If the release of several exposures with radiation is required for checking the measuring results, you must observe the specified cool-down intervals. This is ensured by the automatic exposure blockage (see Operating Instructions).

The pulse/interval ratio is 1:10, which means a 10 second pause has to follow after 1 second of radiation. This pulse/interval ratio is automatically guaranteed by the automatic exposure blockage.

However, preferable for the X-ray tube is a pulse/pause ratio of 1:20.

to insert all screws.

Adhere to the radiation protection guidelines before generating radiation.

Test runs initiated by pressing the T key on the Multitimer followed by actuation of the exposure release button are executed without radiation, i.e. the kV/mA displays remain blank. l

• Replacing parts Always turn the unit OFF before replacing any parts.

When parts located close to the line transformer are to be replaced, switch off the power at the distributor box for the onsite electrical system for safety reasons

To protect electrostatic sensitive devices (ESD) on boards, always wear the wrist band found inside the unit.

The unit must be checked and newly adjusted following the replacement of the DX1 electronics, the X-ray tube assembly or a diaphragm.

The article numbers for ordering spare parts can be found in the spare parts list, order no. 41 63 841. The figures in the spare parts list offer valuable assistance when replacing spare parts.
