# FUNCTIONAL DESCRIPTION
# OPERATING CYCLE:
The Model 900 operating cycle is initiated by momentarily pressing the POWER button located in the POWER section of the front panel. All indicator lights (LEDs) on the panel will illuminate for a short period of time except for the CHARGING and the BATTERY LOW or BATTERY FULL indicators (depending on the charge level of the battery).
The INTERVAL PACE lights (located in the WAVEFORM section of the panel) will step from left to right providing a visual indication of the approximate delay time remaining prior to the application of energy to the probes. The INTERVAL DELAY adjustment sets the amount of time for this delay.
The SEQUENCING lights (also located in the WAVEFORM section of the panel) indicate the application of each of the different waveform outputs from the equipment, seven in total. The SEQUENCE DURATION adjustment sets the amount of time for the total sequenced set.
# OPERATING RANGES:
Adjustment of the output energy intensity is set by the INTENSITY ADJUSTMENT button located in the PROCEDURE section of the panel. Each press of the button will advance the output energy from NORMAL, to MODERATE, to HIGH, and then the sequence will repeat.
The INTERVAL DELAY provides an adjustment range of approximately 1 to 6 seconds.
The SEQUENCE DURATION provides an adjustment range of approximately 10 to 30 seconds.
Waveform frequencies: automatically sequencing from 3 Hz to 300 Hz
# OPERATING MODE:
An indicator shows that the wand set is in use. The indicator will be illuminated when the wand is connected to the machine.
# CALIBRATION:
The Model 900 does not require calibration.

tt We recommend that you calculate the maximum current density and maximum average power density values by using the conductive surface area of the smallest electrodes intended for use with the unit, and include sample calculations in your 510(k). We also recommend that you calculate the maximum power density by using the maximum duty cycle and by averaging over output duration of one second. The maximum average power density should be less than 0.25 watts per square centimeter of electrode conductive surface area to reduce the risk of thermal burns.
{6}------------------------------------------------
# DISCUSSION OF WHY THE DIFFERENCES BETWEEN THE SUBJECT DEVICE AND THE PREDICATE DEVICE DO NOT ADVERSELY AFFECT SAFETY AND EFFECTIVENESS:
The predicate device has a 9v battery, while the subject device has a 6v battery. Generally, a lower voltage battery represents a lower risk factor, and this advantage counts in favor of the Model 900 while providing the device ample power to perform in its intended use. Furthermore, the predicate device does not have any software/firmware/microprocessor control, automatic overload trip, automatic no-load trip, automatic shutoff, low battery indicator display status, nor voltage/current level indicator display status. Each of these safety features exists within the subject device, and therefore provides a safer device than the predicate device. Additionally, the predicate device is much smaller and lighter than the robust Model 900, which will not as easily move about and is designed in this fashion in direct response to user design inputs. Regarding the current, the maximum current density of the Model 900 measures 1.486 mA/cm2 r.m.s. at 500 Ohms of resistance, versus the reported 0.341 mA/cm2 r.m.s. at 500 Ohms resistance of the NūFace, and although this appears to represent a difference within the overall current, it reflects simply a more precise surface contact area that applies the microcurrent as compared to the predicate. The overall current delivered from the Model 900 is unchanged. Finally, the maximum average power density is 366E-6 W at 500 Ohms versus 3.02 µW at 500 Ohms, which represents a larger energy output than the predicate, given the more precise surface contact area, while remaining as safe as the predicate, and more effective at the point of contact than the predicate. Thus, given the foregoing, the Model 900 is at least as safe and as effective as the predicate NūFace device.
All other parameters including the intended use and safety profile remain unchanged.
# NONCLINICAL TEST DATA:
Product Safety testing and electromagnetic compatibility testing conforming to IEC 60601-1 and IEC 60601-1-2, and biocompatibility testing conforming to ISO 10993 were performed in support of the overall safety and effectiveness characteristics of the device, and have confirmed that the Model 900 is safe, effective and substantially equivalent regarding the outputs of the predicate device.
# SUMMARY:
No new issues of safety or effectiveness are raised regarding the Model 900 Facial Toning Device.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
