IMPORTANT NOTES DDWhen using the GPS receiver ••GPS signals cannot pass through metal objects. When using the transceiver inside a vehicle, you may not receive GPS signals. We recommend you use it near a window. Please avoid the areas where: 1. The driver's view will be blocked. 2. The air bags could deploy. 3. The unit becomes a driving obstacle. ••The Global Positioning System (GPS) is built and operated by the U.S. Department of Defense. The Department is responsible for accuracy and maintenance of the system. Any changes by the Department may affect the accuracy and function of the GPS system. ••When the GPS receiver is activated, please do not cover the remote controller with anything that will block the satellite signals. ••The GPS receiver may not work if used in the following locations: 1. Tunnels or high-rise buildings 2. Underground parking lots 3. Under a bridge or viaduct 4. In remote forested areas 5. Under bad weather conditions (rainy or cloudy day) DDAbout GPS antenna This transceiver's GPS antenna is located at the top back of the controller. If the controller's rear panel is covered with any object that interrupts the GPS signals from the satellites, the GPS receiver will not calculate its position. Therefore, when you are using the GPS feature, be sure the controller is positioned so the antenna has a clear view to receive signals from the satellites.
