1.
Apply 2.3V ± 0.005V between TP3(+) and TP4(-) with DC power.
2.
Execute the command “deactmac” to stabilize the value.
3.
Then, execute the command “readbatt”. The returned value is XX.
4.
Confirm that XX is between 98 and A8.
98 < XX < A8 (Hex)
(If XX is out of range, change BBIC)

TP19
1.
Apply 2.6V between TP 3(+) and TP 4(-) with DC power.
2.
Execute the command “deactmac”.
3.
Execute the command “conttx”.
4.
Input Command “rdeeprom 00 01 01", then you can confirm the current value.
5.
Adjust the frequency of TP19 executing the command “setfreq 00 xx (where xx
is the value)” so that the reading of the frequency counter is 10.368000MHz
± 10Hz.
