8. Preliminary Operating Procedures
8.1 Preparation
1) Always wear a lead apron during x-ray exposures.
2) Please leave at least 2 meters (≈6.5 feet) between the operator and the unit. Use the
supplied extended hand switch cable in order to keep minimum safe distance from the unit.
3) Use the proper beam size and technical values to produce the best radiographic results
while minimizing exposure dose.
4) Please make special note of the decimal point on the mAs display in order to acquire the
appropriate intended mAs values.
5) During indoor radiographic use, remember to keep all bystanders at a minimum safe
distance and use the appropriate safety gear while producing exposures.
6) Please pay attention to the proper management and regular maintenance of this equipment.
7) Cumulative doses of radiation are a serious hazard to patients and users of this device.
Please observe the guidelines set forth by your local authorities regarding additional
requirement for protective devices when dealing with machines producing high kV and mAs
radiation values.
WARNING
Please check if the voltage and current of your power supply observes the
specifications written on the system’s labels, found on the backside of the
machine’s body. The levels of voltage must be within ±10% of these standard
values.
CAUTION
Please check all connection lines before operating and producing x-ray
exposures from this machine.
8.2 Collimator Checklist
A. Place the loaded cassette on the patient’s backside.
B. Arrange the SID (Focal Spot to Image Receptor Distance) with measuring tape.
C. Turn on the collimator laser pointer with the “Laser Pointer Switch.”
D. Arrange the beam size according to the scale of the x-ray film with the collimator knob.
E. Collimator and laser pointers will turn off automatically.

8.3 Preheat
1) Overview
All portable x-ray units require preheat procedure to protect the x-ray tube from an instant surge
of current that may damage your device and to insure the longevity and continued safe operation
of your system. Preheating of the x-ray tube is required under the following circumstances:
A. Initial use or installation.
B. Non-use of the equipment after 1 month, stored at lower than room-temperatures.
C. Temperature of the x-ray tube is below 0ºC (32ºF). (Cold tube)
2) Preheat Procedures
Following preheat procedure is recommended.
A. Wear the appropriate safety gear and make sure your equipment is set up in a “radiation
safe” location.
B. In case outdoor temperatures are below 0ºC (32ºF), move the equipment indoors and wait
until the equipment is warmed up before proceeding.
C. In order to preheat the filament of x-ray tube, produce x-rays exposures in 15 second time
intervals.
First Step: 3 quick exposures at a low value (50 kV, 0.4 mAs)
Next Step: 3 more quick exposures at a higher kV (60 kV, 1.2 mAs)
Final Step: the last 3 quick exposures at the max. kV setting (80 kV, 2.0 mAs)
CAUTION
During the X-ray exposures, the equipment makes a “beep” sound.
After the X-ray exposure and while on “Wait” mode, DO NOT push the
“Exposure” button.

10. Hand Switch Functions & Operation
10.1 Introduction
The remote control hand switch is capable of controlling all technical parameters, collimator lamp
and laser pointer functions.
The hand switch is designed with two stages or steps. The first stage of the hand switch preps
and readies your unit while the second stage of the hand switch controls the exposure.
Every function of Remote control is, as explained above, operated by pushing Hand switch in
“Prep Mode”. Each Remote Control function and exposure value selection is as below.
(Fig. 1)
10.2 Remote Control Hand Switch Mode
All of remote control functions are operated by depressing the first stage of the hand switch
(Ready Step). Further explanation on each function and the setting of technical values are as
follows:
