Receiving a Call When your telephone rings, pick up the handactivate and begin talking. NOTE: If you hear an incoming call while picking up the handactivate, you can receive the call by hanging up (placing the handactivate on the cradle) immediately. This will cause the phone to start ringing. Ending a Call Hang up the phone (place the handactivate onto the cradle). Important Tones and Alerts Normal Dial Tone - When cellular service is available, the receiver emits a standard (steady) dial tone. No Service Tone - A fast beeping tone indicates that no cellular service is available. Outgoing Call Restriction - A slower beeping is an indication that calls may be received, but not made, from this particular phone. . Entering User MenuI - Pick up the handactivate - Press Entry code : ‘##XX’ ( ‘XX’ is 2 digit code ) Now you entered User Menu.

Applicant : SUNGIL. FCC ID : R2NSXT-2080 TUNE-UP PROCEDURE There are no user accessible adjustments or tuning in this WLL phone. All necessary adjustments and tuning are performed during manufacture of the product. Any adjustments or tuning after service or repair are done as part of that process as special equipment is required to perform such adjustments.

FCC ID: R2NSXT-2080 MPE Calculations The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user. The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 25.58 dBm + 3.25 dBi EIRP = 28.83 dBm Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) Power density at the specific separation: S = PG/(4R 2 π) S = (361.41 * 2.11) / (4 * 20 2 * π) S = 0.152 mW/cm 2 Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm) Conclusion: The Maximum permissible exposure (MPE) for the general Population/Uncontrolled is 0.55 mW/cm 2 (=f/1500=824/1500).The power density at 20cm does not exceed the 0.55 mW/cm 2 . Therefore, the exposure condition of the EUT is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) R = √(361.41 * 2.11 / 4π) R = 7.80 cm Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log -1 (3.25 / 10) G = 2.11

(b) When measuring the emission limits, the nominal carrier frequency shall be adjusted as close to the licensee’s frequency block edges, both upper and lower, as the design permits. (c) The measurement of emission power can be expressed in peak or average values, provided they are expressed in the same parameters as the transmitter power. 4.3 Occupied Bandwidth The 99% power bandwidth was measured with a calibrated spectrum analyzer. 4.4 Spurious and Harmonic Emissions at Antenna Terminal The level of the carrier and the various conducted spurious and harmonic frequencies is measured by means of a calibrated spectrum analyzer. The spectrum is scanned from the lowest frequency generated in the equipment up to 10 GHz. At the input terminals of the spectrum analyzer, an isolator(RF circulator with on port terminated with 50ohms) and an 870 MHz to 890 MHz bandpass filter is connected between the test transceiver(for conducted tests)or the receive antenna(for radiated tests) and the analyzer . The rejection of the bandpass filter to signals in the 825-845 MHz range is adequate to limit the transmit energy from the test transceiver which appears to a level which will allow the analyzer to measure signals less than-90dBm. Calibration of the test receiver is pe…
