CARTA 2 — Incorrect Atomizer / Dry Herb Mode

The CARTA 2 automatically detects which atomizer type is installed — concentrate or dry herb — and adjusts its behavior accordingly. When the device shows an 'incorrect atomizer' error, it means the detected type doesn't match what's expected, or the atomizer isn't being read at all.

What causes this error

• Wrong atomizer type installed — a dry herb atomizer is detected when the device expects a concentrate atomizer, or vice versa
• Dirty contact pins — residue on the gold pins prevents proper atomizer identification
• Loose or improperly seated atomizer — the device can't read an atomizer that isn't fully threaded in
• Pushed-down base connection pin — the center pin in the base port may be recessed and not making contact

Troubleshooting steps

1. 1
   Confirm you have the right atomizer type

   The CARTA 2 supports both concentrate and dry herb atomizers. Make sure the atomizer you're installing matches the session type you intend to use. Check the label or marking on the atomizer if unsure.

2. 2
   Clean the contact pins

   Remove the atomizer. Use a cotton swab dampened with 70–90% isopropyl alcohol to clean the gold contact pins on both the atomizer and the base port. Residue buildup is the most common cause of detection errors.

3. 3
   Reseat the atomizer fully

   Thread the atomizer clockwise until it's snug — not overtightened, but fully seated. A partially threaded atomizer will not make proper contact and may trigger a detection error.

4. 4
   Inspect the base pin

   Look into the base port and check that the center contact pin is at its normal height (not pushed down). If recessed, apply a small amount of isopropyl around the pin and use a toothpick or pin to gently lift it back into position.

5. 5
   Update firmware

   Connect to the V Browser app (www.focusv.app) via Bluetooth and install any available firmware updates. Firmware updates can resolve atomizer detection issues caused by software bugs.

6. 6
   Submit a support request if issue persists

   If the error continues after all steps above, submit a warranty claim at portal.focusv.com. Include details on the troubleshooting steps taken and your purchase date.
