  If your Udirc Drone fails to pair with the transmitter, several factors could be at play. First, ensure the indicator light is functioning as described in sections 1.2.3. Additionally, there might be interfering signals nearby; try restarting both the drone and the transmitter. If the issue persists, review the user manual for step-by-step pairing instructions to avoid misoperation. In the event of frequent crashes, the electronic components may be damaged, requiring you to buy spare parts from a local seller to replace the damaged parts.

  If the transmitter indicator light on your Udirc Drone is off, it could be due to a few reasons. The most common cause is a low battery, so try replacing the transmitter battery. Another possibility is that the battery's positive and negative poles are reversed; ensure the battery is installed according to the user manual. Lastly, poor contact between the battery and the battery slice can cause this issue; clean any dirt or debris from these contact points.

  If your Udirc Drone is unable to hover and tilts to one side, there could be several reasons: * The drone may need calibration (refer to 7.3 calibration instruction). * A propeller may be seriously deformed, requiring replacement. * The motor holder may be deformed, requiring replacement. * The gyro may not have reset after a crash; place the drone on a flat surface for about 1 second or restart it to calibrate again. * The motor may be damaged and need replacement.

  If you cannot see the picture from your Udirc Drone, it might be due to a few reasons. First, check the wire connecting the camera box for poor contact and ensure it is well connected. If the problem persists, there may be interfering signals nearby; try cutting off and reconnecting the wire. If these steps don't resolve the issue, the camera may be damaged, and you might need to buy a new camera box from a local seller to replace it.
