Window damage on a ULTHERA DS 10-1.5N transducer should be assessed as a classification decision: document the location, extent and visibility of the damage, capture repeatable photo evidence under controlled conditions, and decide between quarantine, qualified testing or replacement. Appearance establishes visible damage only; it does not confirm acoustic output, and no visible scratch is not proof that a unit is safe to use.

This guide owns the window-damage classification decision for the DS 10-1.5N. It does not provide repair, polishing, sealing, coating or membrane-replacement methods, and it does not turn photographs into acoustic-output conclusions. Those questions belong to qualified service and to the output-condition guide.

Use this guide whenever a window finding appears during an incoming inspection or in service. The goal is a repeatable classification that another person can verify: what the damage is, where it is, how visible it is, and which path it triggers. Classification is the step before testing and replacement, not a substitute for them.

Complete the classification in one session where possible. Window findings are easier to compare when the lighting, the preparation and the camera settings are constant, and a unit that is assessed, set aside and assessed again later can produce records that are hard to align.

Document location, extent and visibility of damage

Record where the damage is, how large it is and how visible it is. Note the position on the window, the approximate extent, and whether the damage is visible to the eye or only under specific lighting. The record should allow another person to find the same damage without guessing.

Keep the description neutral: scratch, mark, crack, pitting or surface change, with dimensions where measurable. A neutral record supports a later qualified review; a conclusion recorded at this stage can bias it.

Use consistent terms so the record can be compared over time. A scratch that is later re-measured is only comparable if the first record states where it is and how it was measured; use the same reference points in every assessment of the same unit.

Record the serial and the inspection date on every page of the assessment. A window finding belongs to a specific unit at a specific time, and the record must be attachable to that unit even if the paperwork is separated from the photos.

Cleaning and lighting controls before assessment

Assess the window under controlled preparation and lighting, using only the preparation the manufacturer instructions permit. Consistent lighting and a clean surface make the finding repeatable and comparable over time; uncontrolled conditions can hide damage or create false findings.

Do not polish, seal, coat or alter the window to improve the assessment. Preparation that changes the surface belongs to qualified service, and altering the window to make it look better would invalidate the record.

Record which preparation was used, including the cleaning agent and the lighting, so the assessment can be reproduced. The repeatability of the assessment depends on the conditions being recorded, not assumed.

Do not combine the preparation record with the finding record. The preparation describes how the assessment was made; the finding describes what was seen. Keeping them separate lets a reviewer change the lighting later and re-check the finding without rewriting the original record.

Photo evidence for repeatable review

Capture photos that another reviewer can reproduce: consistent angle, lighting and distance, with the serial or a label visible in the frame where possible. Take more than one photo per finding, and date every image. The photo set is the repeatable part of the record; it lets the same damage be re-examined without the unit present.

Photos document appearance. They do not document output, and a photo that shows no visible damage does not prove the window is acoustically sound.

Keep the photos with the inspection record and the serial of the unit. When the unit is later tested or replaced, the photos allow the decision to be reviewed against the original finding, which is what makes the classification defensible.

Store the photos in a format and location that survive the life of the unit. Compressed chat copies and temporary files disappear; the record should live in the unit file, named with the serial and the date.

Why appearance cannot confirm acoustic output

Appearance and acoustic output are different facts. A window can look intact and still have internal or functional issues, and a visible defect does not by itself prove that output has changed. Acoustic output is established by a qualified test record using a documented method, not by inspection or photography.

State this boundary in the record: the inspection documents what is visible; the output question is answered separately and by qualified parties only.

This boundary also protects the buyer in the other direction: a visible defect is not automatically proof of failed output, so it should not be used to demand a discount without evidence, just as a clean appearance should not be used to claim confirmed performance.

Write the boundary into the record as a line: “This assessment documents visible window condition only. Acoustic output is not assessed here.” A written boundary is harder to misinterpret later than an implied one, and it tells the qualified reviewer exactly what this file covers. Keep that line with the photos so every later viewer of the file sees the boundary first.

Quarantine, test or replace decision path

Finding Recommended path Required next step
No visible damage Continue, do not treat as confirmed safe Complete the inspection record; output condition remains a separate question
Surface mark or scratch, limited extent Hold and request qualified review Qualified inspection or test record before return to use
Crack, puncture or significant damage Quarantine Qualified test or replacement decision; do not use
Damage consistent with drop or puncture Quarantine and escalate The manufacturer instructions state such damage may be permanent and is not covered by warranty

Use the path as a decision rule: quarantine protects the unit and the clinic, hold preserves the evidence, and replacement is decided by qualified assessment, not by appearance alone.

Document which path was chosen and why, with the finding that triggered it. A decision without its trigger cannot be reviewed later, and the trigger is what connects the classification to the qualified response.

If the path changes, record the change and the new evidence that caused it. A finding that first triggered a hold and later triggers replacement should show both steps, because the change is part of the unit’s history and of the clinic’s decision trail. The same applies when a finding is downgraded after qualified review: the new evidence and the date belong in the record.

Required evidence before return to use

Before a unit with any window damage returns to use, require documented evidence that the condition is resolved: a qualified inspection or test record with the system, method, date and attribution, and a decision that identifies the unit and the finding it addresses. The inspection record, photos and the qualified response stay together in the unit file.

Return to use only on that evidence, never on appearance. A finding that was quarantined stays quarantined until the record changes it, and the record must name the unit and the finding it resolves.

Keep the full chain in the unit file: the finding, the photos, the qualified response and the return-to-use decision. If the same unit is assessed again, the new assessment is compared against this chain rather than starting from memory.

Set a review point for any unit whose window finding was not replaced: the condition can change in service, and a recorded review date gives the file a natural next check. The review point is part of the classification record, not an afterthought. Where the clinic keeps multiple transducers, maintain the assessment record for each unit separately and compare findings only within the same unit over time; cross-unit comparisons can reveal patterns, but they do not replace the unit-specific record, and a finding on one unit should never be used to clear another.

When the assessment is complete, review the ULTHERA DS 10-1.5N transducer listing and request current condition, compatibility, remaining-use, inspection, shipping and warranty evidence in writing.

Frequently Asked Questions

Does a scratch on the window mean the transducer must be replaced?

Not automatically. A scratch is a finding that triggers a decision path: hold and request qualified review, quarantine if significant, and replace only on a qualified assessment. Appearance alone does not decide replacement.

Can a clinic repair a damaged window itself?

No. Repair, polishing, sealing, coating or membrane replacement are not buyer-level actions. Any such work belongs to qualified service, and altering the window outside approved methods can invalidate warranty and safety status.
