# QR codes for product manuals

> Link a QR code on the product or quick-start card to the manual, but serve a mobile web page rather than a raw PDF, route by language automatically, and think about setup-time products first — a router's manual cannot require the WiFi the router has not yet provided. Keep the URL stable for the product's life.

## PDF or mobile web — be honest about the PDF

The path of least resistance is uploading the print-ready manual PDF and pointing a
[URL code](/url-qr-code) at it. It works, and for a 4-page leaflet it is acceptable. For
anything longer, a print PDF on a phone is genuinely poor: A4 pages at phone width mean
pinch-zooming every paragraph, diagrams split across page breaks, and a **10–50 MB
download** on whatever connection the customer happens to have.

The better target is a **mobile web manual** — an HTML page with real headings, searchable
text, expandable sections and images sized for a phone. It is more work once, and every
scan thereafter is better. Practical middle ground: link a landing page offering both the
web version and [the PDF as a download](/pdf-qr-code) for people who want to archive it.

| Target | Build cost | Phone experience | Searchable | Offline |
|---|---|---|---|---|
| Print PDF | None | Poor | Within the file | Once downloaded |
| Mobile web manual | Moderate | Good | Yes, and by Google | No |
| Landing page with both | Moderate | Good | Yes | Via the PDF |

## The setup-time trap

Think hard about **when** the manual is needed. A slow cooker's manual is read at leisure
on home WiFi. A router's manual is needed at the exact moment there is **no working
internet in the house** — because the router is the thing being set up. The same trap
catches mesh systems, smart hubs, cars in underground garages and anything installed in a
plant room with no signal.

The rule: **everything needed to reach a working state must be on paper** — or at minimum
reachable over mobile data with a tiny page. The QR code then carries the depth: full
configuration reference, troubleshooting, firmware notes. This split is the subject of
[the printed-manual decision page](/docs/ecommerce/qr-code-instead-of-a-printed-manual);
the short version is that the quick-start stays physical and the encyclopaedia moves
behind the code.

## One code, many languages

A printed manual in 24 languages is mostly paper nobody reads. The linked manual can
route: serve the page in the phone's `Accept-Language`, with a visible language switcher
for the cases where the guess is wrong. One code on the product covers every market,
which also means **one SKU of insert card** instead of per-market print variants — often
the largest real saving.

## URL discipline

The manual link inherits every rule from
[packaging permanence](/docs/ecommerce/qr-codes-on-product-packaging): a stable path on
your own domain (`example.com/manuals/kt-200`), no third-party shorteners, no campaign
URLs, and a redirect that someone documents so a 2031 site rebuild does not orphan every
unit in the field. If the product is serialised you can add the serial as a parameter and
show unit-specific firmware or [warranty state](/docs/ecommerce/qr-code-for-warranty-registration),
but keep the bare path working too.

Print the code at **≥ 2 × 2 cm** on the quick-start card and, ideally, a second copy on
the product itself — manuals are needed years after the box is gone. Label it "Scan for
full manual", and [verify the printed proof decodes](/validate) before the run.

## FAQ

### Should a manual QR code link to a PDF or a web page?
A mobile web page, ideally. Print PDFs are slow to load and painful to read at phone width. If the PDF is all you have, link a small landing page that offers the web version first and the PDF as a download.

### What about products set up where there is no internet?
Keep everything needed to reach a working state on paper. A router manual cannot depend on the WiFi the router has not yet provided. The QR code should carry depth — full reference and troubleshooting — not the critical first steps.

### How do I handle multiple languages with one QR code?
Point the code at one URL that serves the manual in the phone's preferred language, with a visible switcher as a fallback. One code then works in every market and removes per-language print variants of the insert.

### Where should the manual QR code be printed?
On the quick-start card and on the product itself where possible, at 2 × 2 cm or larger. Packaging is discarded quickly, and manuals are most needed years later when only the product remains.
