Tune Up Procedure
Tune up procedure shall be over the power range or at specific operating power levels.

1. It must provide an operational voltage (3.45~4.2V DC) to turn on the phone and
on one certain channel in service mode by means of company proprietary
software.

2. Base station simulator (Rohde& Schwarz CMW500 ) measures the
WCDMA ,LTE phone specific RF characteristics.

3. The maximum gain of each individual phone are adjusted until the target value
met.

Band Tune-up power tolerance(dBm)

GSM 850 PCL = 5, PWR =32.5+-1.5
PCL = 5, PWR =32.5+-1.5(1 slots)
PCL = 5, PWR =30.5+-1.5(2 slots)
GPRS 850
PCL = 5, PWR =28.5+-1.5(3 slots)
PCL = 5, PWR =26.5+-1.5 (4 slots)
GSM1900 PCL = 0, PWR =29.5+-1
PCL=0,PWR= 29.5+-1(1 slots)
PCL=0,PWR= 28+-1(2 slots)
GPRS 1900
PCL=0,PWR= 26+-1(3 slots)
PCL=0,PWR= 24+-1(4 slots)
WCDMA 850 Max output power =23+-1.5
WCDMA 1900 Max output power =23+-1
WCDMA 1900 (Low Power) Max output power =21+-1
LTE BAND7 Max output power =23+-1
LTE BAND7 (Low Power) Max output power =20+-1
802.11b Max output power =20 +-1
802.11b(Low Power) Max output power =18 +-1
802.11g Max output power =20 +-1
802.11g(Low Power) Max output power =19+-1
Bluetooth Max output power =5+-1

Then this appropriate gain settings are stored in each phone individually.
The user has no possibility to change these settings later on, and during manufacturing
each phone will be individual calibrated. The measurement is done in fully calibrated
setup, which is based on a Rohde& Schwarz CMW500base station simulator.
Furthermore, the highest power level is verified afterwards in a call measurement on

three channels (low, middle and high).
