This invention discloses systems and methods for conversion of high moisture waste materials to dry or low moisture products for recycle or reuse. During signal transmission, this frequency is altered in a manner which is known only to the control unit and to the radio key. The radio network controller transmits a page message and application data to the base transceiver stations in the paging zone where the access terminal is located. A voltage-controlled current source utilizes the LED current control signal and an LED current feedback signal for providing an LED current.
