The applicant has been cautioned as to the following:


15.21        Information to User.

   The users manual or instruction manual for an intentional radiator shall caution the
user that changes or modification 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.

                          Measurement Procedures

1. The E.U.T. was connected, through a directional coupler, a 30 dB coaxial attenuator then to a Rohde & Schwarz Spectrum Analyzer.

2. Measurements were made over the range from 1Ghz to 12 Ghz for the worst case modulation at the highest R.F. power settings.

3. All other emissions were 20 dB or more below the limit.

4. Spectrum analyzer bandwidth was set to section 22.917 (h)(1) & (2) as applicable.

5. Measurement Results: All emissions are 30dB below and more.

                                    Measurement Procedures

       1. A description of the measurement facilities was filed with the F.C.C. and was found
          to be in compliance with the requirements of Section 15.38, by letter from the F.C.C.

       2. In the field, the test sample was placed on a turntable at ten and three meters away
          from the search antenna. The test sample was connected to an R.F. wattmeter and
          a 50 ohm dummy load, and adjusted to its rated output.

          In order to obtain the maximum response at each spurious frequency, the turntable
          was rotated. Also, the Search Antennas were raised and lowered vertically, and all
          cables were oriented. Excess power lead was coiled above the system.

Name of Test:          Necessary Bandwidth and Emission Bandwidth

Paragraph:             47 CFR 2.202 (g)


Modulation = CDMA (F9W)


             Emission Bandwidth Calculation:

                    Necessary Bandwidth, kHz          = 1250.00


Justification for CDMA bandwidth of 1.25 Mhz

Reference: TIA/EIA/IS-95

Chip rate is 1.228 Mhz (see page 6-10 of IS-95 {attached}). When we look 3 dB down
from the signal we find 1.25 Mhz. Channel spacing is normally set at this 1.25 Mhz.
Also, one can reference baseband filtering requirements for filtering frequency response
limits.

Radio Frequency Radiation Exposure Limits

The device is installed in a permanent location. It is not operator accessible, and is
contained in a secured environment that is accessible by field service engineers or
installation engineers only. The ERP of the device is less than 1000 Watts. The
Antenna’s used on this device are a typical 16dB gain antenna, with this configuration
and the maximum RF output of the device set to 20 Watts the exposure limit is less than
1000 Watts.
