+# Device Operation Guide
+
+!!! question "Check your device"
+    Not all devices with this firmware support an LED and a button. These features are only available on devices that have them physically present.  
+    If your device does not support these features, the corresponding options will not appear in the web interface.
+
+## LED Indicators
+
+There are three LEDs on the device: Power, Mode, and Zigbee. Each LED behaves differently depending on the device's state and configuration.
+
+### Power LED
+
+- **Blinks at 1 Hz (1)**: Indicates no TCP connection in network mode.
+    { .annotate }
+
+    1. :light_bulb: 1 Hz means the LED blinks once per second.
+   
+- **Constantly on**: Signifies an active TCP connection with the Zigbee chip in network mode.
+
+### Mode LED
+
+- **Blinks at 1 Hz (1)**: Active during the Zigbee chip connection check at bridge startup.
+    { .annotate }
+
+    1. :light_bulb: 1 Hz means the LED blinks once per second.
+   
+- **Constantly on**: Indicates USB mode is active.
+- **Off**: Indicates network mode is active.
+- **Blinks at 3 Hz (1)**: Signals a communication error with the Zigbee chip.
+    { .annotate }
+
+    1. :light_bulb: 3 Hz means the LED blinks three times per second.
+
+### Zigbee LED
+
+- **Controlled by the Zigbee software**: The state can be toggled from the Tools menu.
+
+### LED Control Options
+
+Through the General menu, you can:
+
+- **Disable either LED**: Completely deactivates the selected LED.
+- **Enable Night Mode**: Specify start and end times to completely turn off the LEDs during these periods.
+
+## Button Operations
+
+The device button supports multiple types of presses to manage various functions:
+
+### Types of Button Presses
+
+1. **Short Press (under 3 seconds)**:
+      - Deactivates the LEDs temporarily (this setting resets upon reboot).
+
+
+2. **Long Press (over 3 seconds but under 5 seconds)**:
+      - Switches between network and USB mode.
+      - The Mode LED will start blinking at 1 Hz (1) to indicate that you can release the button.
+        { .annotate }
+
+        1. :light_bulb: 1 Hz means the LED blinks once per second.
+
+3. **Extended Press (over 5 seconds)**:
+      - Activates BSL mode on the Zigbee chip.
+      - The Mode LED will start blinking at 3 Hz (1) to indicate that you can release the button.
+        { .annotate }
+
+        1. :light_bulb: 3 Hz means the LED blinks three times per second.
+
+!!! note
+    This functionality is particularly useful in USB mode with the network disabled.
+  
+### Factory Reset
+
+To perform a factory reset:
+
+1. Power off the device.
+2. Hold down the button.
+3. Power on the device.
+4. Release the button when both the Power and Mode LEDs start flashing at 3 Hz(1).
+    { .annotate }
+
+    1. :light_bulb: 3 Hz means the LED blinks three times per second.
+
+!!! danger "Factory Reset"
+    Performing a factory reset will erase all your settings and restore the device to its original factory state.
