65KX-TG4763B/KX-TGA470B/KX-TGA405B12.7.1.2. HandsetFirst, operate the PC setting according to The Setting Method of JIG (P.56).Then download the appropriate data according to the following procedures.Note:(*2) XXX_YYY: revision number“XXX” and “YYY” vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The SettingMethod of JIG (P.56).12.7.1.3. Range ExtenderFirst, operate the PC setting according to The Setting Method of JIG (P.56).Then download the appropriate data according to the following procedures.Note:(*3) XXX: country code, YYY: revision number.“XXX” and “YYY” vary depending on the country version. You can find them in the batch file, PNZZ- mentioned in The SettingMethod of JIG (P.56).Items How to download/Required adjustmentEEPROM (IC3) Adjusted parameter data is stored in memory.(country version batch file, default batch file,etc.)1) Default batch file: Execute the command “default.bat”.2) Default batch file (remaining): Execute the command“TGA470US_DEF_RevXXX_YYY.bat”. (*2)3) Country version batch file: Execute the command“TGA470US_US_RevXXX_YYY.bat”. (*2)4) Clock adjustment5) 2.35 V setting and battery low detectionX'tal (X1) System clock 1) Apply 2.6V between BATT+ and BATT- with DC power.2) Input Command "sendchar sfr", then you can confirm thecurrent value.3) Check X'tal Frequency.(13.824 MHz ± 100 Hz).4) If the frequency is not 13.824 MHz ± 100 Hz, adjust thefrequency of CLK executing the command "sendchar sfr xx xx(where xx is the value)" so that the reading of the frequencycounter is 13.824000 MHz ± 5 Hz.Items How to download/Required adjustmentEEPROM (IC611) Adjusted parameter data is stored in memory.(country version batch file, default batch file,etc.)1) Change the address “0000” of EEPROM to “22” to downloadthe data.2) Default batch file: Execute the command“TGA405USUSrevXXX_YYY.bat. (*3)”.3) Clock adjustmentX'tal (X501) System clock Clock adjustment data is in EEPROM, adjust the data againafter replacing it.1) Apply 6.5V between DCP ad DCM with DC power.2) Input Command "sendchar sfr", then you can confirm the cur-rent value.3) Check X'tal Frequency.(13.824 MHz ± 100 Hz).4) If the frequency is not 13.824 MHz ± 100 Hz, adjust the fre-quency of CLK executing the command "sendchar sfr xx xx(where xx is the value)" so that the reading of the frequencycounter is 13.824000 MHz ± 15 Hz.
