+#### View or change the duty cycle limit
+**Usage:**
+- `get dutycycle`
+- `set dutycycle <value>`
+
+**Parameters:**
+- `value`: Duty cycle percentage (1-100)
+
+**Default:** `50%` (equivalent to airtime factor 1.0)
+
+**Examples:**
+- `set dutycycle 100` — no duty cycle limit
+- `set dutycycle 50` — 50% duty cycle (default)
+- `set dutycycle 10` — 10% duty cycle
+- `set dutycycle 1` — 1% duty cycle (strictest EU requirement)
+
+> **Note:** Added in firmware v1.15.0

 #### View or change the airtime factor (duty cycle limit)

 **Usage:**
 - `get af`
