RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz. The ambient temperature of the UUT was 81.9% with a humidity of 57%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m APPLICANT: TOYMAX, INC.

FCC ID: NLKTMI8089927 ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The unit under test was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSIC63.4-1992 with the EUT 40 cm from the vertical ground wall.

FCC ID: NLKTMI8089927 CIRCUIT DESCRIPTION: In the transmit mode the momentary switches SW2, SW3, SW4, SW5, SW6, SW7, SW8, SW9, SW10, & SW11 provide input to the encoder integrated circuit - U1. The output of U1 modulates the RF output stage Q2 & Q3 by varing the emitter current. The crystal oscillator Q2 is coupled to the modulated stage Q3 via C5/C6. From Q2 the signal is fed through a doubled tuned circuit con- sisting of L1, L2, C13 & C15 and then to the filter made up of C8, C10, C11, L3 & L4. The output of the filter is connected to the antenna. ANTENNA AND GROUND CIRCUITRY This unit makes use of a external 10" whip antenna. The antenna is inductively coupled. This unit is powered from a 9.0V bat- tery. No ground connection is provided. The unit relies on the ground tract of the printed circuit board. APPLICANT: TOYMAX, INC.
