Also, unless otherwise indicated, the humidity levels were in the range of 10% to 90% relative humidity. Prior to testing, the EUT was tuned up in accordance with the manufacturer's alignment procedures. All external gain controls were maintained at the position of maximum and/or optimum gain throughout the testing. Measurement results, unless otherwise noted, are worst case measurements.

The following measurements were performed with a Narda probe using ANSI/IEEE C95.1 as a guide. 2. Prior to making any measurements, the measurements system was calibrated in accordance with the manufacturer’s procedures. 3. The EUT’s radiating element (antenna) was placed ona1mtall table for ease of testing. For equipment normally operated on a metal surface, a ground plane was used. 4. The remaining equipment necessary to operate the EUT was maintained at a distance from the measurement arrangement suitable to minimize interference with the measurements. 5. The minimum safe distance was calculated from the formula Power Density = EIRP / 4πR 2 (Peak Watts/m 2 ). The calculation is shown with the measurement data. 6. With…

The users manual or instruction manual for an intentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 15.27(a) SPECIAL ACCESSORIES. Equipment marketed to a consumer must be capable of complying with the necessary regulations in the configuration in which the equipment is marketed. Where special accessories, such as shielded cables and/or special connectors are required to enable an unintentional or intentional radiator to comply with the emission limits in this part, the equipment must be marketed with, i.e. shipped and sold with, those special accessories. However, in lieu of shipping or packaging the special accessories with the unintentional or intentional radiator, the responsible party may employ other methods of ensuring that the special accessories are provided to the consumer, without additional charge. Information detailing any alternative method used to supply the special accessories for a grant of equipment authorization or retained in the verification records, as appropriate. The party responsible for the equipment, as detailed in § 2.909 of this chapter, shall ensure that these special accessories are provided with the equipment. The instruction manual for such devices shall include appropriate instructions on the first page of text concerned with the installation of the device that these special accessories must be used with the device. It is the responsibility of the user to use the needed special accessories supplied with the equipment. FCC ID: PYI-15623 MFA p01a0007, d01b0008 TABLE OF CONTENTS RULEDESCRIPTIONPAGE .

The mark and space frequencies are 1200/1800, 1200/2400, and 2400/4800Hz respectively. Tone frequencies are phase continuous; transitions occur at the zero crossing point. The use of a common Xtal oscillator with a choice of two clock frequencies (1.008MHz or 4.032MHz) provides data-rate, transmit frequencies, and RX/TX synchronization. The transmitter and receiver operate entirely independently including individual section powersave functions. The MX469 includes on-chip circuitry for Carrier Detect and RX Clock Recovery, both of which are made available at output pins. RX, TX, and Carrier Detect circuits contain bandpass filters to provide high quality signals in their respective paths. The carrier detect time constant is set by an external capacitor, whose value should be arranged as required to further enhance this product's performance in high-noise environments. The MX469 demonstrates high sensitivity and good bit-error-rate under adverse signal conditions. This low-power device requires few external components and is available in the following packages: 24-pin SOIC (MX469DW), 22-pin PDIP (MX469P), and 20-pin SOIC (MX469D3). 1200/2400/4800bps MSK Modem2MX469
