CARTA Classic — How to Use

The CARTA Classic is a discontinued device that is still fully supported. Before your first session, charge the device fully using the included USB-C cable and an AC/DC adapter rated for 5V 1–2A. Charging takes up to 2 hours.

Basic operation

1. 1
   Charge

   Plug in via USB-C until all LEDs illuminate solid green. Do not leave charging for more than 2 hours.

2. 2
   Power on

   Click the power button 5 times. The LEDs will blink 3 times on startup — the number of LEDs indicates charge level (3 LEDs ≈ 75%).

3. 3
   Select a heat preset

   Press the power button once to activate a preset. Press again to cycle through all 4 presets. A solid blue LED shows the active preset.

4. 4
   Start a session

   Double-click the power button to begin heating. The LEDs blink blue while heating. When the target temp is reached, LEDs turn solid green.

5. 5
   Inhale

   Take slow, steady draws. The slower the draw, the better the vapor stacks. Avoid pulling hard — it can cause concentrate to splash into the inner chamber.

6. 6
   Power off

   Click the power button 5 times to power off after your session.

Heat presets

The CARTA Classic has 4 built-in temperature presets. For a more flavorful experience, lower temperatures (400–500°F) are recommended. Custom temperatures below Preset 1 require the V Browser app (www.focusv.app).

• Preset 1: 500°F
• Preset 2: 630°F
• Preset 3: 770°F
• Preset 4: 850°F

Loading methods

• Cold start — Load concentrate before firing. Best for crumble, shatter, budder. More flavorful. Recommended: 400–500°F.
• Hot start — Load concentrate after the device reaches set temperature. Best for fresh press, resin sauce. Recommended: 450–550°F.

Other controls

• 4x click — Check battery level (number of LEDs = battery level)
