SAFETY and USE

Are NOMAD products safe?

Numerous clinical studies have confirmed that NOMAD X-ray products, when used properly, are as safe, if not safer, than conventional X-ray units. Special internal shielding and our external backscatter shield protect the operator, while true DC voltage and a controlled focal spot minimize the exposure to the patient. For more information on these studies please contact Customer Support.

What personal protective measures should I take when using NOMAD products?

When used properly, NOMAD products require no protection unless mandated by your state. Independent tests have shown that even under the heaviest use operator exposure is one one-hundredth of the annual maximum set by the government for occupational safety.

Individual states may vary in their approval and requirements for handheld X-ray devices, including storage, use of protective vests, and dosimetry badges or rings. Check with your dealer or the state radiation control office for details.

Bystanders should maintain a proper distance from the X-ray by following local radiation safety regulations to avoid undue exposure.

Should I use the NOMAD if I’m pregnant?

Federal and state regulations indicate steps should be taken to limit doses to the fetus of a pregnant woman to 500mrem (or less) during the nine month gestation period and it is recommended that these exposures not be over 50mrem in any month.

Studies demonstrate that typical NOMAD operator radiation doses to are lower than those allowed to pregnant workers (22.5mrem [0.225mSv] per a nine month gestation period or 2.5mrem per month). When the NOMAD is properly used and zone of occupancy is maintained, operator dose is characteristically below the minimum detectible level on monthly reading dosimetry worn by technologists.

However, for increased safety and for peace of mind, Aribex supports the use of additional cautionary measures during pregnancy through the use personal protective apparel as well as monitoring via the use of personal dosimetry. (Numerous personal dosimetry badging services are available and can be found via web searches.)

How do I clean/disinfect my NOMAD?

NOTE: NOMAD devices, batteries, handles, charging units, power supplies, and collimator adapters ARE NOT designed to be subjected to any kind of sterilization procedure, including autoclaving.

When selecting disinfectant or cleaners, use a non-acetone based compound with less than 17% alcohol content. Do not use cleaners intended for hard surfaces, since certain chemical combinations may deteriorate the NOMAD plastic.

NOMAD Dental or NOMAD eXaminer: Turn off the power and detach the battery before cleaning. Ensure the battery charger is unplugged before attempting to clean it. Use a non-acetone based disinfectant wipe  or cloth (according to chemical manufacturer’s recommendations) to wipe the exterior surfaces of the NOMAD  and charger.

NOMAD Pro/Pro 2 and NOMAD Pro/Pro 2 Veterinary: Unplug the charging cradle before cleaning. Use a non-acetone based disinfectant wipe  or cloth (according to chemical manufacturer’s recommendations) to disinfect the exterior surfaces of the NOMAD Pro/ Pro 2 and handset. Leave the handset connected to the device and wipe down all surfaces of the device.

DO NOT spray disinfectant of cleaners directly on any NOMAD device, handset, battery, charging unit or AC power supply. The connecting areas are subject to ingress, and damage to your device may result.
DO NOT operate the NOMAD, battery, handset, charging unit, or power supply if equipment was subjected to moisture (wetting, immersing, or soaking). If this occurs, return the unit to Aribex for service.

How can I register my warranty with Aribex?

You can either mail in the warranty card that came with your unit or fill out the online warranty registration here.

Who registers the product with the state?

The owner has responsibility to register the device with the state. A list of state regulatory websites is available here.

Can you take high quality X-rays holding the unit in your hand even if you are shaking or moving slightly?

Yes. Both experience and data show that the operator can easily hold the NOMAD and NOMAD Pro 2 steady enough to produce diagnostic quality X-rays.The most important factor in producing high quality X-rays is holding the cone/backscatter shield as close to the face as possible.

What imaging media can be used?

A. NOMAD devices work equally well with film, digital media and phosphor plates. Exposure times will vary with the media used.

Can I use an XCP/Rinn-type positioning device with the NOMAD?

Because the NOMAD is so easy to position, most practitioners find a positioning device is unnecessary. In most cases, the NOMAD collimator is held almost touching the patient’s face.

NOMAD customers have reported success using a modified version of their existing Rinn-type positioning devices. The rod must be shortened so that the NOMAD backscatter shield can be flush with the positioning ring itself. The NOMAD backscatter shield should always be employed as far forward (toward the patient) as possible in order to function optimally.

Currently one company has created positioning devices exclusively for the NOMAD. This may be obtained from your dealer or by contacting  ClikRay™, item # 001-220 (see http://www.clikray.com/clikray-for-aribex/).

NOTE: Aribex does not manufacture, sell, or formerly endorse any positioning device from any manufacturer. This information is provided solely for the convenience of our customers.


BATTERIES

How do I maintain the batteries on the NOMAD Dental and NOMAD eXaminer?

Batteries and handsets should be carefully removed from the X-ray head each night when storing the device.

It is recommended that when using NOMAD Dental or eXaminer devices to leave the spare battery/handset in the charger at all times.

Use the active battery/handset until the low battery indicator is displayed, then remove it and swap it for the battery/handset that has been in the charger. Eventually, the battery/handset will stop holding a charge and require replacement from your dealer.

Battery Questions

NOMAD Dental/Examiner

Type of battery NiCd 14.4V
Expected exposures per full charge At least 100 1-second exposures.
Lower time settings will increase number of exposures.
OK to leave battery in charger? Yes, recommended
Expected recharge time 4 hours
Expected battery life 200 recharge cycles
OK to recharge every evening? No, wait until low battery indicator

The batteries on these devices are NiCd (Nickel-Cadmium).

Nickel-Cadmium batteries can retain a memory, so when possible, wait for the low battery indicator before charging.

For optimum performance, leave the battery pack in the charger for eight hours or more once every week or after 10 charge/discharge cycles. This balances the cells, keeps the pack at peak performance and extends the usable life of the pack.

If a NOMAD Dental or NOMAD eXaminer is not in use for an extended length of time, the handles should still be charged once every three months to ensure the integrity of the battery cells.

Using Automatic Tune-UpMode (NOMAD Dental and eXaminer only)

The Automatic Tune-Up Mode equalizes or balances the individual cells in the battery pack allowing it to function at peak capacity. Battery packs should be tuned up weekly or after 10 charge/discharge cycles or whenever the pack no longer delivers the same amount of work. To use the automatic tune-up mode, simply place the battery pack in the charger and leave it for at least eight hours. The charger will cycle through the following modes.

1. The red light will blink continuously indicating that the 1-hour charge cycle has started.

2. When the 1-hour charge cycle is complete, the light will stay on continuously longer blink. This indicates that the pack is fully charged and can be used at this time.

3. Whenever the pack is left in the charger after the initial 1-hour charge, the charger will begin the Automatic Tune-Up Mode. This mode continues up to 8 hours or until individual cells in the battery pack are equalized. The battery pack is ready for use and can be removed at any time during the Tune-Up Mode.

4. Once the Automatic Tune-Up Mode is complete the charger will transition to a maintenance charge; no indicator light shows the Tune-Up Mode.

How do I maintain the rechargeable handsets on the NOMAD Pro and NOMAD Pro 2?

Handsets (batteries) should be carefully removed from the X-ray head each night when storing the device.

Alternate handsets each week to maximize service live. Eventually, the handset will stop holding a charge and require replacement from your dealer.

The handsets contain Lithium Polymer batteries. They may be recharged every day, but a fully charged handset should NOT be left on the charging cradle overnight. Remove the handset once it is fully charged. Always unplug the charger when not in use.

Do not spray disinfectant or cleaners directly on the handsets. Any fluid entering into the handset via ingress can severely damage the handset.

When selecting disinfectant or cleaners, use a non-acetone based compound with less than 17% alcohol content. Do not use cleaners intended for hard surfaces, since certain chemical combinations may deteriorate the NOMAD Pro 2 plastic.

Battery Questions

NOMAD Pro/Pro 2
Type of battery Li-poly 22.2V
Expected exposures per full charge At least 100 1-second exposures.
Lower time settings will increase number of exposures.
OK to leave handset in charging cradle? No, remove after fully charged.
