OL6IM-2000Single-Mode CDMA Cellular Phone

FCC RF EXPOSURE INFORMATION 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. Do not use the phone with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Please contact your local dealer for replacement antenna. Body-worn Operation This device was tested for typical body-worn operations. To comply with FCC RF exposure requirements, a minimum separation distance of 0.4 inches (1.0 cm) must be maintained between the user’s body and a third party belt-clip/holster, including the antenna whether extended or retracted. Third-party belt-clips, holsters, and similar accessories used by this device should not contain any metallic components. Body- worn accessories that do not meet these requirements may not comply with FCC RF exposure requirements and should be avoided. For more information about RF exposure, please visit the FCC website at www.fcc.gov Read this information before using your phone

The ESN is plated from fraudulent contact and tampering. The ESN is encoded using multiplication by a polynomial and ESN data programmed in the memory with other information. c) The ESN is factory-set and can not be altered, transferred, removed or otherwise able to be manipulated. Cellular mobile equipment is specifically designed such that any attempt to remove, tamper with, or change the ESN chip, its logic system, or firmware originally programmed by the manufacturer will render the transmitter inoperative.

The EUT is placed on the turntable and loaded with the integral antenna. A receiving antenna located 3 meters from the turntable receives any signal radiated from the transmitter and its operating accessories. The receiving antenna is varied from 1 to 4 meters and the polarization is varied (horizontal and vertical) to determine the worst-case emission level.

SK TELETECH FCC ID: OL6IM-2000 5 Single-Mode CDMA Cellular Phone (824-849MHz) 3.3 FIELD STRENGTH OF SPURIOUS RADIATION – §2.1053 Operating Frequency: 824.70 MHz Channel: 1013 (Low) Measured Conducted Power: 23.2 dBm Modulation: CDMA (Internal) Distance: 3 meters Limit: 43 + 10 log 10 (W) = 37.48 dBc Frequency Level AFCL (dBc) (MHz) (dBm) (dB) POL (H/V) ERP (dBm) 1649.40 < - 66.00 30.55 H - 23.33 46.21 2474.10 < - 76.50 34.22 H - 30.16 53.04 3298.80 < - 84.48 37.15 H - 35.21 58.09 4123.50 < - 92.10 40.22 H - 39.76 62.64 4948.20 < - 100 Notes: 1. The bandwidth is set per §22.917 (RBW = 1MHz, VBW = 1MHz). 2. The spectrum was checked from 10 MHz up to 20GHz. 3. < -100dBm is below the floor of the spectrum analyzer. 4. The EUT is manipulated through 3 orthogonal axis and the worst-case emission are reported. 5. The EUT is placed 3.0 meters away from the receiving antenna and the ERP is calculated using the formula. ERP (dBm) = 10 Log 10 (((r(mV/m)/1 x 10 6 ) 2 / 49.2/1 x 10 -3 ) ERP (dBm) = 10 Log 10 [ (3 x FS/1 x 10 6 ) 2 / (49.2) x 1000] ERP (Watts) = {(3 x FS)/1 x 10 6 } 2 / 49.2 Note: The antenna factor and cable loss were determined prior to the test.
