8. Operation 1) Prep aration A. Wear a lead apron for x-ray exposures. B. Leave at least 2 meters away from the unit or use extended hand switch cable in order to keep safe distance. C. Apply pro per beam size a nd techni cal values to produce the best radiographic results while minimizing exposure dose. D. Be careful about the decimal point on the mAs display in order to acquire intended mAs values. E. For the indoor radiography for the p atient in t he bed, ask visito rs to leave the room for a wh ile and keep safe distance from the patient. F. Pay attention to proper management of the equipment and careful maintenance. G. Cumulative radiation dose should not exceed the recommended amount. Ask the guide and advice of experts for the requirement of additional protective devices at frequent use of high kV and mAs. WARNING Please check if the voltage and current of the power supply observe the specifications written on t he system labels, attached t o backside of machine body. The levels of voltage should move within ±10% of the standard values.



CAUTION Please check up all the line connections before the operation and x-ray exposures of machine.



2) Collimator Check-up A. Place the loaded cassette on the patient’s backside. B. Arrange the SID (Focal Spot to Image Receptor Distance) using a scale located on the side of the collimator. C. Turn on the collimator lamp and laser pointer by pushing collimator/laser on switch. D. Adjust the size of the x-ray beam in accordance with the film size using the x-ray field adjustment knobs. Turn off the collimator and laser pointer after 30 seconds on the timer.

3) Preheat (1) Overview All portable x-ray units require preheat procedure to protect the x-ray tube from an instant surge of current and to secure long and safe operation of the system. Preheat of x-ray tube is required under following situation. A. Initial use or installation. B. Non-use of the equipment over 1 month at low temperature C. Temperature of x-ray tube is below 0℃ (32℉). (Cold tube) (2) Method to Preheat Following preheat procedure is recommended. A. Install the equipment at a safe place for radiation. B. In case outdoor temperature is below 0℃ (32℉), move the equipment indoor and warm it up. C. In order to preheat filament of x-ray tube, exposure x-rays in 15 second time intervals. First: 3 exposures at 50 kV @ 0.2 mAs Second: 3 exposures at 80 kV @ 5.0 mAs Third: 3 exposures at 110 kV @ 5.0 mAs CAUTION Beep Sound will occur during x-ray exposu res.

2) APR Mode A. Select APR Switch. B. Select the size of patient by APR Size Select Switch. C. Select the subject region by APR region select switch. D. Select the radiography direction by APR direction select switch. E. Select wanted values by density up/down switch. F. APR Storage 1) Users can save 30 (Body Size 2 X Region 5 X Direction 2) data for APR. 2) If you press Store Switch after changing kV/mA/Sec, the changed condition is saved.



※ NOTICE※ APR data can not be saved when OVER LED is lighted on or Density is not Zero. In this case, change radiography condition (kV, mA, Sec) and density and resave.



※ NOTICE※ Under APR mode, the last saved technique values are automatically selected and display and saving of data is available only at x-ray exposures.



※ NOTICE※ As explained at previous pages, the exposure switch should be operated by 2 stages. It, however , instant exposure is available when the filament board is heated enough.

Setting and adjusting tube kV (Pre shipment adjustment) -Turn off the power switch. -Connect Oscilloscope to HT Controller inside machine. -Chanel 1: connect the probe of oscilloscope to TP11 (IP F/B) and GND (TP16, 17 or 18). -Chanel 2: connect the probe of oscilloscope to TP10 (EP F/B) and GND (TP16. 17 or 18). Chanel 1: mA, 1V = 10mA Chanel 2: kV, 1V = 25kV -Turn on the power switch. -Set the conditions a s 4 0kV and 0. 1mAs (2 0mA) and observe mA waveforms at Channel 1 of Oscilloscope. -If the value at channel 1 is not 2V (20mA), adjust the mA output with VR1 of HT board. And observe if the waveform of Channel 2 is 40kV (1.625V). -Set the conditions as 1 00kV and 0.2 mAs (4 0mA) and observe mA waveforms at Channel 1 of Oscilloscope. -If the value at channel 1 is not 4 V (40mA), adjust the mA output with VR1 of HT board. And observe if the waveform of Channel 2 is 100kV (4V). ※ CAUTION ※ As the kV value of channel 2 is automatically adjusted by standard parameters, Additional calibration is not required.

B. Setting and adjusting tube mA -Turn off the power switch. -PCB HT board is located under control panel. -All DIP swit ches o n PCB HT b oard a re at of f con ditions. (Note: DIP switch i s lo cated i n this pl ace normally. -Chanel 1: connect the probe of oscilloscope to TP11 (IP F/B) and GND (TP16, 17 or 18). -Chanel 2: connect the probe of oscilloscope to TP10 (EP F/B) and GND (TP16. 17 or 18). Chanel 1: mA, 1V = 10mA Chanel 2: kV, 1V = 25kV -Turn on the power switch. -Set the conditions as 4 0kV and 0. 2mAs (1 0mA) and observe mA waveforms at Channel 1 of Oscilloscope. -If the value at channel 1 is not 4V (40mA), adjust the mA output under calibration mode. -If you press “kV Down”, “APR S”, “APR L” switch for 2 seconds, it is enter into calibration mode.



Calibration mode is displayed as below. “C00” on the kV segment is kV calibration code and “20” on the mA segment is mA calibration value. Refer to content of each menu at table 1.

Calibration Code



Calibration Data



Press mA up switch (Refer to the OP sheet) and it displays as follows. C01 is calibration code of tube current (40mA at 40-50kV) and 40 is calibration data of tube current. .(40mA from 40 to 50kV) -Select mA with mAs up/down switch (Refer to the OP sheet) -Press the ‘Store Key’ longer than 1 second after application (Refer to the OP sheet) -Exposure x-rays after saving the data -If the measu red data is not 4V(40 mA), reset t he cali bration dat a. Set the mA value s as thi s method. -Table 1 represents calibration code and data of each tube current vales at 5kW. C. Filament preheat calibration -If the preheat calibration data or VR1 are set in wrong way, over current or low current can occurat X-ray tube. -There are two methods about preheat calibration. Calibration data can be changed by tube conditions. -VR1 can be applied to overall tube current. Filament preheat calibration dat a can be applied to each tube current. -Turn on the power switch. -Under normal mode, press [‘S’+‘L’+‘kV_Down’] Key in case of human and [‘Bird’+‘Dog’+‘kV_Down’] Key in case of veterinary over 2 seconds.
