APPLICANT: MONICOR ELECTRONIC CORPORATION FCC ID: GES4BAM2000S REPORT #: F:\CUS\M\MON\MON35U9.RPT PAGE #: 1 2.983(d) (7) Complete Circuit Diagrams: The circuit diagram is included as Exhibit 5A-5B. The block diagram is included as Exhibit 4. The part list is in- cluded as Exhibit 6A-6C. (8) Instruction book. The instruction manual is in- cluded as Exhibit 10. (9) Tune-up procedure. The tune-up procedure is given in Exhibit 7A-7B. (10) Description of all circuitry and devices provided for determining and stabilizing frequency. The transmitter frequency is controlled by a crystal, the crystal specifications are included in PAGE 20. (11) Description of any circuits or devices employed for suppression of spurious radiation, for limit- ing modulation, and for limiting power. This circuitry is described in PAGE 9A-9G. Limiting Modulation: The transmitter audio circuitry is contained in IC101, and IC102. Limiting Power: There is no provision for limiting power. (12) Digital modulation. This unit does use digital modulation. 2.983(e) The data required by 2.985 through 2.997 is sub- mitted below. 2.985(a) RF_power_output. ERP was measured by connecting a signal generator to a dipole antenna and adjusting the level to produce the same field strength at the UUT.
