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 not 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 b 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 the receiver. Consult dealer or an experienced radio/TV technician for help. This equipment has been certified to comply with the limits for a class B computing device, pursuant to FCC rules. In order to maintain compliance with FCC regulations, shielded cables must be used with the equipment. Operation with non-approved equipment or unshielded cables is likely to result in interference with radio and TV reception. The user is cautioned that changes and modifications made to the equipment without the approval of the manufacturer could void the user’s authority to operate this equipment. Page - 3 – Fluent Systems – SmartLink System Introduction Congratulations on your purchase of the Smartlink (tm) monitoring system from Fluent Systems. Smartlink (tm) is an innovative electronic system that allows you to continuously monitor the application of anhydrous ammonia fertilizer from within the tractor cab. This patent-pending product utilizes modern RF and electromagnetic sensing technologies in a novel and revolutionary way and dramatically improves the process by which anhydrous ammonia is applied to your field. The Smartlink (tm) is a two-module system composed of a tank module that sits atop the field tank and a cab module that is positioned within the tractor cab. The tank module can be set directly on top of the existing fluid level gage with no modifications required to the tank and no tools necessary. The tank module continuously monitors the fluid level within the field tank and then sends it in a wireless fashion to the display module mounted inside the tractor cab. The display module receives the signal from the tank module, decodes the information and displays fluid level to the user via a liquid crystal display. The cab module allows the farmer to quickly input implement and tank size. This information is processed along with groundspeed data from the tractor to output other useful information to the farmer including application rate per acre, time remaining until tank is empty and a "tank-empty" audible alert. The Smartlink (tm) is a capable agricultural aid that provides convenience and added functionality not present today. The Smartlink (tm) is a useful addition to the existing process of applying anhydrous ammonia to farmland worldwide. It solves the difficult task of measuring fluid in a hazardous environment while remaining completely safe to use. Information gathered by the Smartlink (tm) can be used during application to increase operator efficiency and decrease common problems associated with the current method. It also accurately reports fertilizer application rate per acre, which adds greatly to the farmer's information. The Smartlink (tm) is a system that includes one display module and one tank module, along with necessary groundspeed interface, power cable and cab mounting hardware. The product carries a one-year limited warranty. Page - 4 – Fluent Systems – SmartLink System Features and System Components Your Smartlink (tm) System comes complete and ready to use with the following components: Cab Module Tank Module Windshield Adaptor Ground Speed Adaptor 12 V Cigarette Lighter Adaptor Carrying Case Page - 5 – Fluent Systems – SmartLink System Operation: General Operating Conditions: Tank Unit Cab Unit Maximum Temperature XX degrees F XX Minimum Temperature XX degrees F XX The Smartlink (tm) system has been designed for durable, robust operation and should withstand years of use. The unit does contain precision electronic components and should be treated carefully to ensure trouble free operation. Do not expose the either Cab or Tank unit to excessive heat or cold. The Tank unit has been designed to be water and dust resistant. Prolonged exposure to driving rain, excessive sleet or snow should be avoided. If the Tank unit will not be used for extended periods of time, the unit should be removed from a tank and stored inside it’s protective case. The batteries should be removed to prevent leakage. Do not leave the Cab Unit in excessive heat or cold or direct sunlight for prolonged periods of time. The user should be aware that extreme temperatures inside tractor cabs can cause damage to the Cab Unit. Avoid exposing the Cab Unit to extremely dusty conditions. Avoid dropping either the Cab or Tank unit. While both units have been designed for shock and vibration resistance, sensitive electronic components can be damaged due to excessive shock or vibration. Tank Unit Batteries The Tank unit runs on three AA sized batteries. Do not mix old batteries with new batteries. Do not use different types of batteries together. There is no need to turn the tank unit on or off. Under normal use, the tank unit will run three months before needing to change batteries. If…
