Page 5: Getting Started
1.0 Getting Started 1.1 Intended Use The NOMAD eXaminer X-ray System is intended for general, non-medical use – materials imaging, industrial inspection, pathology/forensics, and veterinary care that requires small-area radiographic imaging. The use of NOMAD eXaminer on live humans is expressly prohibited by regulation. -

Page 7: Safety Precautions
ANUAL 2.0 Safety Precautions 2.1 Radiation Safety This x-ray unit may be dangerous to operator and bystander unless safe exposure factors and operating instructions are observed. Operators must follow all guidelines dictated by applicable occupational safety regulations and in- house radiation protection program, especially in regard to operators who are pregnant or expect to become pregnant. - Page 8 NOMAD As shown in graphic representations, maximum protection (green area) from backscatter radiation (red area) exists when the NOMAD is positioned near the subject, is perpendicular to the operator, and the backscatter shield is fully extended toward the subject. An exposure can be terminated for any reason abruptly releasing...

Page 10: Cleaning
NOMAD There are no user serviceable parts inside the NOMAD. Do not open the device housing. Doing so will void the warranty. NOMAD should not be used in environments where flammable cleaning agents are present. Locate the battery charger out of the way, but in a convenient place (see section 5.0, Battery Replacement). -
Page 11: Setup And Check
ANUAL For long-term storage, it is recommended to fully recharge batteries every 3 months. 3.0 Setup and Check 3.1 The Backscatter Shield In addition to the lead-lined cone, the backscatter shield provides additional protection to you, the operator, and features an adjustable position to permit exposures made at various angles. Ideally, the shield should remain fully extended to the outer edge of the cone, especially if the subject to be imaged is immediately in front of the cone (see 2.1,... -
Page 12: Attaching A Charged Battery
NOMAD 3.2 Attaching a Charged Battery Properly orient and carefully insert the newly charged battery into the base of the NOMAD handle. A properly oriented battery should click into place without force (forcing the battery into position may damage the battery and/or the NOMAD). -
Page 13: Optional Checks
ANUAL For continued use, insert the secondary, replacement battery (which should be charged in advance). See section 5.0, Battery Replacement, for more information. NOTE: 3.4 Optional Checks The NOMAD is factory calibrated and tested prior to release (see your Certificate of Conformance), so there are no adjustment options. -
Page 14: Operation
NOMAD 4.0 Operation 4.1 Powering Up POWER Press and release button to turn NOMAD on (after approximately 2.5 half minutes of inactivity, NOMAD shuts off automatically). When the power is turned on a single, long audible signal and an example illuminated numeric (LED) display indicate the unit has power. -
Page 15: Positioning Subject And Enabling The Device
ANUAL 4.4 Positioning Subject and Enabling the Device Properly position the subject and yourself before enabling NOMAD (to prevent accidental exposure). ENABLE Press and release to ready the device; be sure to re-enable NOMAD if any subsequent changes are made to the time setting prior to exposure. -
Page 16: Battery Replacement
Do not attempt to charge damaged batteries. An authorized distributor, Aribex, and your local recycling center will accept spent or damaged batteries. Order new 14.4V batteries from Aribex or your authorized distributor. Do not use batteries from other sources, which invalidates the warranty. -
