- Insert 2 AA batteries (included) into each remote, observing the correct polarity (+/-).
- Close the battery compartment cover.
2. Charging the Tank Batteries
Connect the rechargeable tank battery to the USB charging cable. Plug the USB cable into a standard USB power adapter (not included) or a computer USB port. The charging time is approximately 2-3 hours for a full charge, providing about 30 minutes of play time.
3. Filling Water for Smoke Effect
For the realistic smoke effect, fill the small water bottle with clean water. Locate the water inlet on the tank (usually near the rear exhaust vents). Carefully squeeze water into the inlet until the reservoir is full. Do not overfill.

Operating Instructions
1. Power On and Pairing
Turn on the power switch on both the tank and its corresponding remote controller. The tank will automatically demonstrate all functions with cool lights. The 2.4Ghz technology allows multiple tanks to operate simultaneously without interference, enabling 2v2, 3v1, or free-for-all battles.
2. Basic Controls

3. Battle Functions and Effects
- Shooting: Use the shooting button for machine gun fire, cannon button for cannon fire, and missile button for missile launch.
- Recoil and Vibration: When shooting, the tanks will exhibit recoil, and the remote control will vibrate, simulating a realistic battle experience.
- Smoke Effect: Activate the smoke effect via the spray switch on the tank. The tank will emit simulated smoke from its exhaust.
- Sound Effects: Enjoy realistic engine sounds, machine gun fire, cannon blasts, and missile launches. Sound can be turned off with one click on the remote.
- Lights: Tanks feature cool lights for enhanced play, especially in darker environments.
- Life Indicator: Each tank has four life indicator lights. When a tank is hit, a light will turn off. When all four lights are off, the tank is defeated and will make a defeated sound. Press the start button on the remote to reset and begin a new round.

4. Terrain Capability
The battle tanks can climb a maximum slope of 40 degrees and can roll over small obstacles. They perform best on hard, flat surfaces like asphalt, stone roads, or carpet. Avoid thick grass or very uneven terrain to prevent damage to the tracks.
