Tuneup Procedure -Each modem is tested during routine factory testing; -The modems are tested to GSM standards using an Agilent 8960 GSM test set. -Multiple channels and power levels are tested and if correction is necessary. -If correction is necessary, the "Automatic Power Control" software tables are adjusted in the modem's Flash memory. -After passing all tests, the modem is labeled and assigned an IME

Prediction of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 where:S = power density P = power input to the antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna Maximum peak output power at antenna input terminal:30.00(dBm) Maximum peak output power at antenna input terminal:1000(mW) Antenna gain(typical):3.3(dBi) Maximum antenna gain:2.13796209(numeric) Prediction distance:20(cm) Prediction frequency:1900(MHz) MPE limit for uncontrolled exposure at prediction frequency:1 (mW/cm^2) Power density at prediction frequency:0.425334(mW/cm^2) Margin of compliance:-3.7(dB) 2 4R PG S π = (mW/cm^2) (mW/cm^2)
