   According to section 1.1310 of FCC 47 CFR Part 1, limits for maximum permissible exposure (MPE)

   are as following

Note1. Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their

       employment provided those persons are fully aware of the potential for exposure and can exercise control

       over their exposure. Limits for occupational/controlled exposure also apply in situations when an individual

       is transient through a location where occupational / controlled limits apply provided he or she is made aware

       of the potential for exposure.

Note2: General population/uncontrolled exposures apply in situations in which the general public may be exposed,

       or in which persons that are exposed as a consequence of their employment may not be fully aware of the

       potential for exposure or can not exercise control over their exposure.

 IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, the antenna(s)

used for this transmitter must be installed to provide a separation distance of at least 20 cm from all

persons and must not be co-located or operating in conjunction with any other antenna or transmitter. No

change to the antenna or the device is permitted. Any change to the antenna or the device could result in

the device exceeding the RF exposure requirements and void user’s authority to operate the device.

  Report No.: RXA1502-0023MPE                                                              Page 5 of 5


RF Exposure Calculations:
The following information provides the minimum separation distance for the highest gain antenna provided.

This calculation is based on the conducted power, considering maximum power and antenna gain. The

formula shown in KDB 865664 D01 is used in the calculation.

Equation from KDB 865664 D01, Edition 97-01 is:
                                                              2
                                                   S= PG / 4∏R
                                                                                   2
                      where:   S = power density (in appropriate units, e.g. mW/cm )

                               P = Time-average maximum tune up procedure (in appropriate units, e.g., mW)

                               G = the numeric gain of the antenna

                               R = distance to the center of radiation of the antenna (20 cm = limit for MPE)

So, the numeric gain (G) of the antenna with a gain specified in dB is determined by

   Numeric gain (G)=10^(antenna gain/10)=10^(2/10)=1.58 dB
  CDMA Cellular:     PG = 25dBm+ (1.58dB) =26.58dBm=455mW
  CDMA PCS:          PG = 24dBm+ (1.58dB) =25.58dBm=361.41mW
                       R =20 cm

                       ∏= 3.1416
    Solving for S, the power density at 20 cm is
                                                          2                            2
             Band                  Test Result (mW/cm )           Limit Value (mW/cm )
        CDMA Cellular                        0.09                     0.56 mW/cm²
          CDMA PCS                           0.07                       1 mW/cm²



Note: For mobile or fixed location transmitters, minimum separation distance is 20cm, even if calculations

      indicate MPE distance is less.
