                          TEST PROCEDURE

GENERAL:   This report shall NOT be reproduced except in full   without
the written approval of TIMCO ENGINEERING, INC.

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 94º with a humidity of 20%.

                    TEST PROCEDURES CONTINUED


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




ANTENNA_AND_GROUND_CIRCUITRY

This unit makes use of a short, antenna.    The antenna is induc-
tively coupled. The antenna is self contained, no provision is
made for an external antenna. This unit is powered from a 9.0V
battery.

No ground connection is provided.   The unit relies on the ground
tract of the printed circuit board.

 SAMPLE CALCULATION:        FSdBuV/m = MR(dBuV) + ACFdB.

 TEST PROCEDURE: The procedure used was ANSI STANDARD C63.4-1992. The
 spectrum   was scanned from 30 MHz to 1000 MHz. When an emission was
 found, the table was rotated to produce the maximum signal strength.
 The antenna was placed in both the horizontal and vertical planes and
 the worse case emissions were reported. The UUT was tested in 3
 orthogonal planes.


 TEST RESULTS:     THE UNIT DOES MEET THE FCC REQUIREMENTS.
