If your SplashDrone 4 and remote controller won't pair

About Pairing

The remote controller and the aircraft are paired at the factory before shipping. There is NO NEED to pair them for your first use. After turning on, the aircraft and the remote controller will pair in 2 minutes. It might take extra time to pair depending on the signal interference of the environment.

⚠️ONLY pair the remote controller for the following condition: After turning on the aircraft and the remote controller for more than 5 minutes, the remote controller signal status bar still shows the Unpair sign.

To ensure the pairing process is successful:

• Please strictly follow the steps to pair.
• Please ensure that you are able to see the light indicator at the bottom of the aircraft. If you can’t see the light indicator, please take off the bottom plate so that you are able to see it.
• Please use a timer to count the time needed to press the pair button.

💡 The pair button is delicate. Press the pair button gently to prevent unexpected damage to the button.

Identify SN Number

Before pairing, look for the SN number inside the aircraft battery compartment:

For SN number ending with V01

For SN number ending since V02 (V02, V03, V04 ... etc)

For SN number ending with V01

To pair

1. Turn over the aircraft and place it on the carrying case. Unscrew and take off the bottom plate.
2. Turn on both the aircraft and remote control. Wait for 1 minute until the right LED light turns from flashing to solid.
3. Long press the pair button for 10 seconds. (Do not press shorter than 10 seconds) The right LED will start flashing. *If the right LED does not flash, please repeat the step until the right LED starts flashing.
4. Wait for 1 minute until both the left and right LED turn solid. The reset process is complete.
5. Now, long press the aircraft’s pair button for 5-10 seconds. (Do not press shorter than 5 seconds) The right LED will start flashing. *If the right LED does not flash, please repeat the step until the right LED starts flashing.
6. Quick press the remote control’s pair button twice. The left and right LED will flash alternatively.
   • *If the left and right LED do not flash alternatively in 10 seconds, please repeat this step again until the left and right LED flash alternatively.
   • *If the left LED does not flash and the right LED has already turned solid. Please repeat the pairing process again from step 1.
7. The pairing process can take up to 3 minutes. When the pairing process is complete, the right LED will turn from flashing to solid, and the left LED will stay flashing. The remote controller will prompt “Aircraft initializing, please wait”.
8. Assemble the bottom plate back, turn over the aircraft and place it on a level surface. The “Aircraft initializing, please wait” prompt will disappear in 30 seconds, and you are now ready to fly.

If the pairing process does not succeed, please try to pair it again from step 1.
