Point
CK5
1. Confirm that the voltage between test point "CK5" and GND is 1.85V±0.02V.
2. Adjust the 1.8V voltage of CK5 executing command "bandgap XX" (XX is the
value).
-
1. Confirm that the voltage between "CK6" and GND is 2.775V±0.1V.
-
1. BBIC Confirmation (Execute the command "getchk").
2. Confirm the returned checksum value.
Connection of checksum value and program number is shown below.
-
1. Apply 6V between JT101(+) and JT102(-) with current limit of PSU to
200mA.
2. Confirm that the charge current is ON/OFF.
3. SW to decrease current limit of PSU to 100mA.
4. Confirm that the charge current is stable.
-
1. Stop supplying 6V to JT101(+) and JT102(-).
2. Execute the command "charge".
3. Confirm that the returned value is 0x01 (hex).
-
1. Apply 3.8V ± 0.005V between BATT(+) and BATT(-).
2. Execute the command "Backloff", then "readbatt".
3. Confirm:
29
returned value
4. Adjust the Battery Monitor executing command "wreeprom 00 01 01 XX",
then "wreeprom 00 36 01 XX-0E" (XX is the value).
-
1. Apply 3.5V between BATT(+) and BATT(-).
2. Confirm that there is no flashing of Battery Icon.
3. Apply 3.3V between BATT(+) and BATT(-).
4. Confirm that there is flashing of Battery.
SYRI
1. Execute the command "conttx".
2. Adjust the frequency of SYRI executing the command "setfreq xx (where xx
is the value)" so that the reading of the frequency counter is 10.368000MHz
±10Hz.
