The device for which we are seeking certification under Part 15.249 is a transmitter only. Please refer to the Radiometrix spec, attached. The RF Transmitter is part of a wireless bingo game system. Essentially the transmitter sends updated information to the individual players “handheld” bingo game (each time a ball is called out). The receiving device is in the handheld bingo game, which contains the 914.5 Mhz receiver. The receiver is the corresponding part of the RF system designed by Radiometrix. The model number of the receiver is RX3. Refer to attached Radiometrix spec. The GameTech handheld game units are called the TED and TED 2 C units. They are referred to in the GameTech Installation and Support Manual, which you should have received with the application package. They take the place of manual cards or booklets. TED 2 C TED
