RG611B_manual_rev.C 2014.02.06 To allow safe use, be certain to observe the following points. Please Read Before Use Basic Precautions for Safe Use of the 2.4GHz System
(1) The 2.4GHz band is not a frequency exclusively for use with RC airplanes. This frequency band is in common use with the ISM (industry, science, and medical care) band which is widely used for short-distance transmissions such as microwave ovens, wireless LAN, digital cordless phones, audio, gaming devices, cell phone Bluetooth. Therefore, the response of the 2.4GHz system may be reduced in urban areas. Further, as it also is used for ham and local area radio communication for mobile identication, please pay attention to the possible inuences from these. In the event of any adverse radio wave interference on an existing wireless station, immediately stop emitting radio waves and take the interference avoidance measures.
(2) At race tracks and airelds, minimize the use of devices that can aect the transmitter/receiver and be sure to conrm the safety beforehand. Also, always follow the instructions of the facility sta.
(3) If an aircraft is allowed to pass behind a building, pylon, trees, etc. the radio-wave range is blocked, the response may drop, even result in losing control. Always let aircraft run or y within a range that you can visually observe. In order to protect against injury to users or third parties, or damage to property, points that must certainly be observed are shown below. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment o and on, the user is encouraged to try to correct the interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna. 2. Increase the separation between the equipment and receiver. 3. Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected. 4. Consult the dealer or an experienced radio/TV technician for help. This device complies with Industry Canada Licence-exempt RSS-210. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. DANGER!
Not following this advice carries high risk of death or serious injury to the user or third parties. Do not use this product in the rain as water may cause electronic devices to malfunction. This product carries a risk of injury due to heat, re, and electric shock. Never disassemble or modify this product. When turning on the receiver, the engine (or motor) can start rotating at high speed, causing injury. Before turning on, always set the transmitter throttle stick to the lowest speed position. Turn on the transmitter rst then the receiver. To shut down, switch o the receiver rst and then the transmitter. WARNING!
Not following this advice may result in death or serious injury the user or third parties. Do not use this receiver in combination with other manufacturers products such as servos, gyros etc. Never allow the receiver to receive a strong impact as the electronic components in the receiver are susceptible to damage. If degraded servo movement is detected, stop operating immediately. Identify the source of the problem before further operation (check battery voltage, etc). Do not use the product in the following locations, as there will be a risk of an out-of-control condition or accident:
Where interference exists. Where there is trac passing nearby. Near high-tension electric lines, buildings, or in mountainous areas, etc. Near houses or people. Near radio or TV transmitters If the receiver becomes submerged in water, it may appear to operate normally after being fully dried. However, it may malfunction at a later time. Do not continue to use the product contact your JR distributor to arrange an inspection. CAUTION!
Not following this advice may cause injury to the user or third party (or cause damage to property). Is there enough battery voltage for both the transmitter and receiver?
Is there any fuel spillage on the receiver, servos, etc. that was caused by leakage from the fuel tank? Is there enough fuel?
Check that no linkage interferes with the aircraft body. Conduct a vibration test by restraining the model and setting the engine (or motor) to full power whilst keeping your hands well clear of the propeller. Check that each control surface moves correctly. For the initial ights of a new model always y in a safe place, avoid ying at great distance, and keep the model close to the landing area for several minutes until you are fully condent that the receiver is operating correctly. If you have further questions, please contact your local dealer or JR distributor in your country.
