Reference 15.105 Federal Communications Commission (FCC) Requirements, Part 15 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 off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ---Reorient or relocate the receiving antenna. ---Increase the separation between the equipment and receiver. ---Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. ---Consult the dealer or an experienced radio/TV technician for help. 15.21 Regulatory information / Disclaimers The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 15.19(a)(3) 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. (2) This device must accept any interference received, including interference that may cause undesired operation. 1. Warnings - Before you using your system, please check the power of transmitter and receiver. - When you use the Ni-Cad batteries to power your system, DO NOT connect the power adapter when you are operating the transmitter. To prevent accidents, overheating and short circuits. - Please turn on the transmitter first and then the receiver, to prevent the loss of control. - To prevent operate the system outdoor on rainy days, the system are not designed for waterproof. - Please extend the antenna to the full length when operating the transmitter. - Please check the near area that there is no two or more models using the same frequency at the same time. 2. Introduction LG2-01 is a pistol grip FM radio system, it allows user to select 2 or 3 channel operation mode. In 2 channel mode, it provides the D/R adjustment and D/R override. Most pistol grip radio system only support the 2 channel for steering and throttle, but LG2-01 offers the 3rd channel to control the extra function in 3 channel mode, like the gear change. The LG2-01 is the best choice for the R/C cars and boats, especially for 3 channel control requirement models. 3. Product Features - Eagle shape, full of speedy feeling, catch the other people eyes. - 2 /3 Channel switching function, meet the varied requirements for the models. - Dual rate for steering - Dual rate override for steering (2 channel mode) - Steering and throttle servo reversing - Extra 3 rd channel control (3 channel mode) - Steering and throttle sub trim - Exchangeable steering wheels, bundle extra small size wheel for racing - 3 LED indicator to show the power status - Removable crystal design for frequency channel change - Build in the DC jack and default bundling charger for rechargeable batteries - 7:3 travel length for throttle and brake - BEC system with receiver for varied batteries voltage - Receiver supports the E.S.C.

LG2-01 transmitter with antenna B. RX-02 receiver C. Servo x 2 D. External power switch E. Dry battery holder F. Neck strap G. Charger H. Sticker I. Manual J. Steering wheel (big size) 6. System Connections Receiver and servo connections Non-electric Model - When you install the system in an non-electric model (or mechanical type speed control), you should use the battery holder to supply the power for receiver E.S.C. Installation Model Connection Precautions A. Installation Note - After you installed the system, please check the receiver, servo, and battery connections, make sure all the connections are fully inserted. - The package contains the rubber bungs, if the slot is not in using, it can be plugged with the bung to prevent the water splashing. - To protect absolutely the system from water or oil damage, you can place it in a plastic bag or waterproof box. - Please remember this; always turn your transmitter on first and off last. Failure to do so may result in loss of control and can damage your servos and/or linkage. B. Receiver Note - Keep the receiver away from motor or engine when attaching to the chassis of car or boat. - Keep the receiver away from the power wires to prevent the interference. - Refer you model instructions, run the antenna up the antenna tube to gain the best receiving effect. - DO NOT cut off the excess antenna wire, or it will shorten the operation range. - The receiver includes a BEC (Battery Eliminator Circuit) system, which eliminates the need for an extra receiver battery when used with a mechanical or electronic speed control. The battery power…
