Device and Antenna Operating Configuration:

     The EUT is placed on the test bench. RS232 port is connected to a support laptop. All other ports
     are left unpopulated for evaluation of RF signal at the antenna port.

     The spectrum analyzer is connected to Port 1 of the EUT. Port 1 thru Port 4 utilizes the same RF
     circuit.

     Digital attenuator set to : 9

     Freq: 905MHz, 915MHz, 925MHz
     Modulation: OOK.

     Measured Peak Power= 29.04dBm, 29.92dBm, 29.18dBm (0.80 W, 0.98W, 0.83W)

     Antenna to be used with this product:
     Sirit, single-element patch antenna , ANTENNA-024, Gain 15 dBi.
     Transcore, Universal Toll Antenna , AA3152       Gain: 14dBi
     European Antennas, flat Panel Antenna, FPA15-916H/1159, Gain 15.4dBi


     Frequency range of measurement = Fundamental
     Test environment conditions: 25°C, 45% Relative Humidity, 100kPa

     The EUT obtains 12V DC power from a support DC Power supply.
     Modification: 0.1uF capacitor added to the T/R control line C196.

     Center frequency was set to 905MHz, 915MHz and 925MHz. The licensee will adjust the transmit
     frequency according to appropriate frequency plan at the time of licensing.

Test Procedure:

     This equipment is evaluated in accordance with the guidelines set forth in OET Guide 65 & ANSI
     C95.1 for the US and Health Canada Safety Code 6 & RSS 102 for Canada.

Summary:

Exemptions:
In the case the equipment meets compliance requirements by exemption the product is approved for use under
mobile or portable conditions without further testing under the condition that any additional collocation or
simultaneous transmission requirements (including necessary separation distances) have been met.

MPE Calculation Results:
It is assumed that the manufacturer shall design the equipment such that the minimum separation distance of
29.8cm or greater is met or that the manufacturer provides a protection guide (or installation instructions) to the
end user such that the antenna(s) may be installed in accordance with the manufacturer’s instructions in such a
manor to maintain the minimum separation distance.
