SIZE: 210MM × 297MM PN#F5-6606-000-0100 80gsm OPERATING INSTRUCTIONS INSTRUCTION SHEET & PACKAGING MUST BE RETAINED SINCE IT CONTAINS IMPORTANT INFORMATION: BATTERY INSTALLATION BATTERY REQUIREMENT: Vehicle: Built-in Rechargeable Battery Transmitter: 2 x AA batteries (included) *ALKALINE AA BATTERIES IS RECOMMENDED ATTENTION PARENTS It is recommended that this toy and all accessories be periodically examined for potential hazards and that any potentially hazardous parts be repaired or replaced. VEHICLE The vehicle is powered by a built-in non-replaceable rechargeable battery. The included rechargeable battery is not charged prior to shipment and must be charged before the first use. Charging The Vehicle 1. Make sure the vehicle’s ON/OFF switch is in the OFF position. (See Diagram 1) 2. Open the battery cover. (See Diagram 1) 3. Plug the charging cable USB socket to an USB certified port, i.e., desktop computer / laptop computer / smartphone charger / tablet charger / car changer 4. Turn the vehicle's ON/OFF switch to "CHARGE" position. 5. The LED light on car body will flash to show vehicle is charging. 6. Once the light turned OFF, the vehicle is fully charged. Unplug the USB socket from the USB certified port. 7. Put back the charging cable into the compartment and replace battery cover. (See Diagram 3) TRANSMITTER 1. Unscrew to open the battery lid. Insert a new 2 x AA batteries. (See Diagram 2) 2. Replace the battery cover. Note: Remove battery after you have finished using your vehicle. Caution : Built-In Battery Safety Information 1. The vehicle includes a non-replaceable battery. Do not open, disassemble or alter the vehicle in anyway. 2. Adult supervision is required when charging the vehicle. 3. Charge battery in isolated area. Keep away from flammable materials. 4. Do not expose to direct sunlight. 5. Do not recharge the toy if it is hot. Allow it to cool before recharge. 6. Do not allow the batteries to get wet. 7. Carefully read the instruction guide and use the batteries correctly. 8. Rechargeable batteries are only to be charged under adult supervision. 9. Routine examination for damage to the plug, enclosure and other parts. In the event of any damage, the toy must not be used with USB port until the damage has been repaired. 10. This toy is not intended for children under 3 years old. CARE Never drive the vehicle on a wet floor, on sand, grass, carpet, in mud, rain or snow. These can cause damage to the vehicle. Do not expose the vehicle to extreme temperatures. To protect the vehicle’s wheel mechanisms from lint and hair, do not drive it on carpet. Occasionally wipe the vehicle with a damp cloth to remove any dirt/dust from wheels. Do not use harsh chemicals to clean the vehicle. Modifying or tampering with the vehicle or the transmitter’s internal components can cause a malfunction. HELPFUL HINTS Running the vehicle continuously for long periods of time generates high levels of heat. Heat causes wear and tear on the motor. When the vehicle’s battery pack goes flat, let the vehicle cool at least 10 minutes before installing a newly charged battery pack. This helps keep heat levels down. If the vehicle’s motor runs but does not respond to the transmitter, move the transmitter closer to the vehicle and try again. If a CB radio is used nearby, it might interfere with the control of the vehicle. If this happens, move the vehicle and transmitter away from the CB radio. The vehicle cannot be operated near devices with transmitters that use the same frequency. Check the packaging to see which frequency your vehicle uses. If the vehicle moves slowly, and a recharged battery pack has been installed, check the wheel mechanisms for lint, thread, hair or dust. HOW TO PLAY START TO PLAY PAIRING TRANSMITTER WITH VEHICLE 1. Turn ON the vehicle (See Diagram 3). 2. Install 2 x AA battery in the transmitter, the pairing LED light on the transmitter will flash (See Diagram 2). 3. If pairing success, the pairing LED light will turn OFF 4. You must pairing the transmitter with the vehicle within 45 seconds, after 45 seconds you must push the control on the transmitter to pair again. 5. You must repeat pairing again when the transmitter needs to replace new batteries. Notes: 1. If pairing failed, reinstall the battery of transmitter, move closer and then try again. 2. If more then one vehicle are pairing at the same time, pair each vehicle one by one. Vehicle has memory to store the paired data, no need to pair each time play until replace the battery in transmitter. OPERATION 1. Operate the vehicle with the transmitter (See Diagram 4). 2. Turn OFF the vehicle and the transmitter after playing and remove all batteries from the transmitter. FRONT WHEELS STEERING ADJUSTMENT 1. If the vehicle does not run straight forwards, adjust the lever for satisfactory alignment on the underside of the vehicle. (See Diagram 5) 2. If the vehicle runs towards left, turn "Steering Alignment Lever" towards "R" 3. If the vehicle runs towards right, turn "Steering Alignment Lever" towards "L" ENGLISH Battery cover Unscrew to open. 1 23 4 2 x AA batteries LED 5 Vehicle Transmitter Forwards/Backwards 2.

CAUTION: To prevent battery leakage: Be sure to insert batteries correctly and always follow the product and battery manufacturers' instructions. Never mix old and new batteries (replace all batteries at the same time). Never mix Alkaline, standard (Carbon Zinc) or rechargeable (Nickel-Metal Hydride) batteries. Only batteries of the same or equivalent type as recommended are to be used. Do not use RECHARGEABLE batteries, unless specified. Non-rechargeable batteries are not to be recharged. Rechargeable batteries are to be removed from the product before being charged. Rechargeable battery is only to be charged by adults or by childr…

1 INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a R/C VEHICLE operating at 2.4G Band. The EUT can be powered by DC 6.0V (1 x 6.0V rechargeable battery). Once use the USB cable charging to the EUT, the wireless function will be disabled. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna. Antenna Gain: 0dBi. The normal peak radiated output power (e.i.r.p) is: -19.0dBm (tolerance: +/- 3dB). The normal peak conducted output power is -19.0dBm (tolerance: +/- 3dB). Modulation Type: GFSK. According to the KDB 447498: The Maximum peak radiated emission for the EUT is 77.2 dBμV/m at 3m in the frequency 2480MHz The EIRP = [(FS*D) ^2 / 30] mW = -18.03dBm which is within the production variation. The Minimum peak radiated emission for the EUT is 74.0dBμV/m at 3m in the frequency 2402MHz The EIRP = [(FS*D) ^2 / 30] mW = -21.23dBm which is within the production variation. The maximum conducted output power specified is -16dBm= 0.025mW The source- based time-averaging conducted output power =0.025* Duty cycle mW <0.025 mW(Duty cycle <100%) The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.53 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing. The duty cycle is simply the on-time divided by the period: The duration of one cycle = 15.000ms Effective period of the cycle = 2.5362ms DC =2.5362ms / 15.000ms =0.1691 or 16.91% FCC ID: BY34723-24GB
