RADIO OPERATOR Futurecom requires the OCR operator to ensure FCC Requirements for Radio Frequency Exposure are met. The OCR output power has to be set such that the maximum Effective Radiated Power (ERP) does not exceed 5W at the antenna. The minimum distance between all possible personnel and the antenna at 5W ERP must be at least 25.4cm (10.0”). - Page 7 For General Population/bystanders: r = (ERP/4ПS) = (5000/4П(931.0125/1500)) = 25.32cm. The MPE safe distance is therefore at least 25.4cm (10.0”). ATTENTION! The MOBEXCOM OCR must be restricted to occupational use only to satisfy FCC RF Exposure requirements. 8A535X03 Rev. Preliminary-00 Page 7 of 17...

Run the programming software by clicking on the shortcut or typing the batch file name. -
Page 13: Using The Programming Software For Setting Up The Ocr
For successful On-Line operation the OCR needs to be properly connected prior to commencing the programming / system setup: 1. The OCR must be plugged into the Futurecom subrack and supplied with proper DC power supply. 2. The RF IN and RF OUT ports need to be connected to the corresponding multicoupling ports or to adequate power rating 50 Ohm loads (or to the test equipment). -

Set the power output to the calculated level required to reach the Donor site (allow for at least 6 dB margin). Key up the OCR by setting PTT to ON. Read the “own” ?RSSI level from the Maintenance screen 8A535X03 Rev. Preliminary-00 Page 14 of 17... - Page 15 Set the RSSI CAS Threshold to at least 10 dB higher than the measured “own” RSSI level (for example if the measured “own” RSSI level was -120dBm, set the RSSI CAS Th ON to -110dBm or higher). 8A535X03 Rev.
