DJI O3 Air Unit: Low Power and Temperature Protection Guide

Understanding Low Power and Temperature Protection

The DJI O3 Air Unit has built-in protection mechanisms to prevent damage from overheating. This can manifest as:

  • The unit entering a low power state
  • OSD (On-Screen Display) not showing in the goggles
  • Video recording stopping

Causes of Overheating

  1. Extended use in high temperatures
  2. Poor ventilation
  3. Prolonged ground time without takeoff

Solutions and Preventive Measures

1. Utilize Airflow for Cooling

The DJI O3 Air Unit is designed to use airflow during flight for heat dissipation. To prevent overheating:

  • Avoid extended use when ambient temperature is high
  • Ensure good ventilation around the air unit
  • For prolonged ground operations, use a small fan to cool the air unit

2. Manage Automatic Temperature Control

The goggles have an automatic temperature control feature that can be adjusted:

  1. Enter the goggles menu:
  • Click and press the five-dimensional button on the goggles
  1. Navigate to: Settings → Device → Automatic Temperature Control
  2. Set it to OFF to disable automatic temperature control

Note: Even with automatic temperature control off, the air unit can still overheat. Always monitor your equipment during use.

3. Allow Cooling Time

If overheat protection activates:

  • Stop using the air unit
  • Allow it to cool down completely before resuming operation

Troubleshooting Steps

  1. Check for Low Power State:
  • Look for a message in the goggles indicating low power mode
  • Verify if the OSD is not displaying
  1. Inspect Recent Flight Logs:
  • Analyze logs for any temperature-related warnings or shutdowns
  1. Test After Cooling:
  • Allow the unit to cool completely
  • Perform a short test flight to check if normal function resumes
