Setup and Installation
Charging the VIFLY Beacon
The VIFLY Beacon comes with a built-in rechargeable battery. Before first use, ensure the device is fully charged. Connect the VIFLY Beacon to a standard USB power source using a compatible charging cable. The charging indicator will show the charging status.
Mounting the Device
The VIFLY Beacon is designed for easy, wireless installation without the need for soldering.
- Choose a Location: Select a secure and visible location on your drone. Common areas include the drone's frame, arm, or top plate.
- Attachment Methods:
- Adhesive Pad: Use the provided 3M adhesive pad to firmly attach the Beacon to a flat surface on your drone. Ensure the surface is clean and dry before application.
- Zip Tie: For a more secure attachment, especially on drone arms or irregular surfaces, use the provided zip tie to fasten the Beacon. Ensure it is tight enough to prevent movement but does not damage the drone.
- Orientation: Position the Beacon so the buzzer and LED are not obstructed, allowing for maximum sound and light output.

Operating Instructions
Powering On/Off
Locate the power switch on the VIFLY Beacon. Slide the switch to the "ON" position to activate the device before flight. Slide to "OFF" after use to conserve battery.
Flight Mode
During normal flight, the VIFLY Beacon remains in a standby mode, monitoring for unusual movement.
Crash Detection and Alarm
If the drone crashes or experiences significant impact, the built-in motion sensor will detect the event. The Beacon will then enter an alarm sequence:
- Pre-Alarm Phase: The device may emit quiet beeps for a short period (e.g., 30 seconds) to confirm a potential crash.
- Alarm Mode: If no further movement is detected after the pre-alarm phase, the Beacon will activate its loud beeper and flashing LED lights. The beeping pattern and light intensity may increase over time to aid in location.

Automatic LED Light Activation
The VIFLY Beacon features a light sensor. In low-light conditions or darkness, the LED lights will automatically begin flashing to improve visibility and help locate the drone, especially during night searches.

Theft Deterrent Function
If the VIFLY Beacon is in an active alarm state and detects quick, unauthorized movement (e.g., someone picking up the drone), it will emit a continuous, aggressive beeping sound to deter theft and alert the owner.

Maintenance
- Charging: Regularly charge the VIFLY Beacon to ensure it is ready for use. A fully charged battery provides extended alarm duration.
- Cleaning: Keep the device clean from dirt, dust, and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the VIFLY Beacon in a cool, dry place when not in use. For long-term storage, it is recommended to charge the battery periodically to maintain its health.
- Inspection: Periodically inspect the device for any signs of damage to the casing or charging port.
Troubleshooting
Device Not Beeping/Flashing
- Check Battery: Ensure the VIFLY Beacon is sufficiently charged. Connect it to a USB power source.
- Power Switch: Verify the power switch is in the "ON" position.
- Motion Detection: The alarm activates upon detecting a crash or significant impact. Gentle movement may not trigger the full alarm sequence.
- Light Sensor: The LED light activates automatically in dark conditions. Test in a dimly lit environment.
Alarm Too Quiet
- Obstructions: Ensure the buzzer is not obstructed by drone components or debris.
- Environment: External noise levels can affect perceived loudness. The device is designed to be loud in typical outdoor environments.
Short Battery Life
- Full Charge: Ensure the device is fully charged before each use.
- Age of Battery: Like all rechargeable batteries, capacity may decrease over time with repeated charge cycles.
