Shen Zhen Yixun Electronic Technology Co., Ltd. Tune-up (dBm) procedure This is to formally certify that:
The tune up procedures of Mobile Phone (FCC ID:2AQ8SCHAPERONT200) The tune up procedures of is not open to end user. The end user is not allowed to perform final tune. All the power and frequency set up were finished at the manufacturer stage. Tune up procedure shall be over the power range or at specific operating power levels. Procedure:
1. Set the phone to operational voltage and on one certain channel in a special service mode by means of company proprietary software. 2. The actual power is measured at several power levels. 3. The gain factors of each individual phone are adjusted via the Board-test SW using automatic adjustment arithmetic until the Tune-up Range (dBm) value is met. It must provide an operational voltage (DC 3.7V by battery) to turn on the device and on one certain channel in service mode by means of company proprietary software. spectrum analyzer(Agilent, N9020A) and Power meter
(DARE, RPR3006W)measures the 2.4G device specific RF characteristics. Base station simulator (R&S CMW500) measures the 2G/3G/4G device specific RF characteristics. The maximum power of each individual channels are adjusted until the target value met. Band GSM850 Tx Channel Frequency (MHz) Burst-Averaged output Power (dBm) Tune-up 128
