Diagnostic X-Ray Systems, 21 CFR
Subchapter J, Part 1020; obtainable from FDA Center for Devices and Radiological Health,
Department of HHS, 2098 Gaither Road, Rockville, MD 20850.
All personnel authorized to operate o
r
service this equipment should be fully acquainted with the
established maximum permissible doses, safety recommendations, and procedures derived from the
following sources:
National Council on Radiation Protection Report No.102 (Medical X-Ray and Gamma Ray
Protection for Energies up to 10 MEV - Equipment Design and Use); from NRCP Publications;
P.O. Box 30175, Washington, D.C. 20014.
CARELESS OR IMPROPER USE OF X-RAY EQUIPMENT CAN BE EXTREMELY HAZARDOUS.
It is imperative that this equipment be operated and serviced only by trained personnel familiar with the
safety precautions required to prevent excessive exposure to primary X-ray radiation, the dangers of
exposure to X-ray radiation, and the proper use of the equipment discussed in this manual.
The MinXray model HF120/60HPPWV PowerPlus TM is a mono-block type high frequency portable x-ray
unit. The HF120/60HPPWV PowerPlus TM can be used with conventional diagnostic film or with solid-state
digital radiographic sensors. It is supplied with the x-ray tubehead/collimator, detachable AC power cord,
and detachable exposure cord with 2-stage exposure switch. The MinXray HF120/60HPPWV
PowerPlus TM high frequency diagnostic x-ray unit is designed for use with the MinXray model XGS MKIV
LW or equivalent stand capable of providing secure, stable support that allows for proper positioning of the
x-ray unit for radiographic imaging.

RECORD KEEPING REQUIREMENTS

Manufacturer Responsibility - The FDA believes that plant-based manufacturers must
include in their assembly instructions a specific requirement that the assembler perform a
test(s) for the applicable requirements of the FDA performance standard at the time of
installation. A thorough explanation of the equipment required and step-by-step
instructions must be provided by the component or system manufacturer. The instructions
should include a requirement to record key data to demonstrate at a later data that all tests
were performed and that the equipment was left in full compliance with the standard. The
FDA's Department of Health and Human Services will insure that these assembler test
instructions are provided through a close review of the information submitted by
manufacturers in initial, model change and annual reports. Plant-based manufacturers who
do not include a final compliance test in their assembler instructions could be subject to
disapproval of their quality control and testing program.

Use the retractable tape measure on the collimator to position the HF120/60HPPWV
PowerPlus TM at the proper source-image distance (SID) for the image to be taken.
Turn on the collimator light by pressing the button on the collimator. The light will remain on for
approximately 30 seconds, and then automatically turn off. The shutters of the collimator can be
adjusted at any time with the 2 knobs on the collimator. The size of radiation field will only be

Position the patient. Adjust the collimator position so the cross hair projected by the collimator
light is aligned with the anatomical point of interest and the center of the image receptor.
Collimate the size of the light field so that it stays within the dimensions of the image receptor.
15
Make sure that the main power switch is OFF. Connect the AC power cord to a grounded
electrical outlet. Check the label on the HF120/60HPPWV PowerPlus TM for the correct AC
input voltage and amperage required.
Turn on the main power switch on the HF120/60HPPWV PowerPlusTM. The kV and sec LED
displays will light and remain on. The HF120/60HPPWV PowerPlusTM has internal circuitry to
automatically compensate for variations in the input voltage to assure consistent kV and mA
Select the kV output by pressing the arrows below the kV display to choose 40 to 120 kV. mA
output is selected automatically based upon the kV output selected.
Set the exposure time for the view to be taken, and the imaging medium used. Press the arrows
below the sec. display to choose the exposure time between 0.01 and 5.0 second exposures.
The display can be changed between mAs and sec. selected by pressing the shift switch (#)
and pressing the down arrow (▽) below the kV display.

When you are finished using the HF120/60HPPWV PowerPlusTM,turn off the main power
switch, disconnect the AC power cord and exposure cord, and put the stand with the
HF120/60HPPWV PowerPlus TM attached into its correct configuration for transport.
Five different technique settings can be stored in memory for quick recall on the
HF120/60HPPWV PowerPlus TM. To store a technique setting, press the Memory Storage button
MR then press Memory Recall button M1. This will store the technique setting displayed in
memory position M1. Repeat this process for storing the different technique setting in M2-M5
as desired. Stored technique settings can be easily recalled by simply pressing M1-M5.
Memory Storage use two (2) size AA alkaline batteries inside Battery Compartment, located on
the back side of equipment. Open the Battery Compartment using a coin, turning the
compartment lid counterclockwise 90°. If there are no batteries in the Battery Compartment,
use some adhesive ta

Insert two (2) size AA alkaline batteries in the Battery Compartment, with the + end toward
the Battery Compartment lid. Reattach the Battery Compartment lid and lock it with a coin,
turning it clockwise 90°.
The first stage pre-heats the filament of the x-ray tube. When this stage alone is
depressed and held, " READY " indicator will light after 2.5 seconds, indicating the
filament was heated and the unit is read

The second stage initiates the x-ray exposure for the time set in the sec display.
When the second stage is fully depressed, x-ray will be emitted, the X-RAY indicator
will light, and an audible signal will be heard. PRESS AND HOLD THE FIRST AND
SECOND STAGE BUTTONS TOGETHER UNTIL THE EXPOSURE HAS
TERMINATED. This is a " dead man" exposure switch -- x-ray exposure will

If ERROR INDICATOR is lit even after the EXPOSURE SWITCH is released, it means an
unusual situation has occurred. Turn off the MAIN POWER SWITCH, wait 3 minutes, then start
procedures over again.

If the ERROR INDICATOR remains on, contact your dealer or MinXray for service.
Check all cords and cord connections.
Check the exposure buttons--the exposure must terminate if the button is released during an

Indicators
Check the X-RAY indicator for proper operation when both exposure buttons are depressed and
held.
Check the kV adjustment for proper operation.
Check the timer for proper operation.
Check collimator shutters for proper operation.
Check collimator light bulb for proper operation.
Make sure the certification and identification labels are in place.
Check for any loose or missing screws.
Check for oil leaks.
Check for any physical damage.
Maintenance
Clean the HF120/60HPPWV PowerPlus TM as needed with a damp sponge or cloth and mild
The following must be checked before each use:
Tubehead
The operator must not stand in the primary x-ray beam.
The operator should wear a monitoring dosimeter while operating this unit. It should be worn
where it is not covered by a lead apron.
X-ray exposure should be kept as short as possible.
The presence of radio frequency (RF) or electromagnetic radiation may adversely affect the
operation of this device. Please keep this equipment away from likely sources of RF radiation.
Safety Precautions
During exposure the operator must stand as far as possible from the patient being x-rayed, and
should wear a lead apron or stand behind a lead shield.
