FCC RF EXPOSURE INFORMATION Please read this information before using the radio modem In August 1996 the Federal Communications Commission (FCC) of the United States with its action in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC regulated transmitters.Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of this phone complies with the FCC guidelines and these international standards. Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the phone, or result in violation of FCC regulations. CAUTION To comply with FCC RF exposure requirements this device must be operated with a minimum separation distance of 4cm (1.6 inches) between the user/nearby persons and the antenna, with the antenna in the vertical upright position, which is the intended position of the antenna when operating the RIM 902 radio modem installed in the unit.

After rechecking our ERP data sheet it was found that the numbers submitted for the upper frequency (901MHz) were entered incorrectly. We have revised the ERP data sheet with the appropriate numbers as attached. Please note that the SAR measurements were performed prior to the ERP test and the conducted power was maintained at 33dBm for both upper and lower frequencies. Since this is a clerical error and not a measurement error the SAR results were not affected. 2. For future filings we will ensure that the file sizes do not exceed 2MB.

The field of maximum intensity was found by rotating the EUT approximately 360 degrees and changing the height of the receive antenna from 1 to 4 meters. The field strength was recorded from a calibrated spectrum analyzer for each channel being tested. A half-wave dipole was substituted in place of the EUT. The dipole was fed through a directional coupler and the power at the coupler port was monitored. A signal generator and power amplifier controlled the dipole, and the input level of the dipole was adjusted to the same field strength level as the EUT. The feed point for the dipole was then connected to a calibrated power meter and the power adjusted to read the same as the coupler port previously recorded, this is to account for any mismatch in impedance, which may occur at the dipole antenna. The conducted power at the antenna feed point was recorded. The forward power for the dipole was then determined and the ERP level was determined by adding the forward dipole power and the dipole gain in dB. For readings above 1GHz the above method is repeated using standard gain horn antennas.
