)* Battery Monitor Check &
Adjustment (Important)
-
1. Apply 2.3V ± 0.005V between BATTERY (+) and BATTERY (-) 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 A7.
98 < XX < A7 (Hex)
(If XX is out of range, change BBIC)

CLK
1. Apply 2.6V between BATTERY (+) and BATTERY (-) with DC power.
2. Execute the command “EnableClockOutput”.
3. Input Command “sfr", then you can confirm the current value.
4. Check X’tal Frequency. (10.368 MHz ± 100 Hz).
5. If the frequency is not 10.368 MHz ± 100 Hz, adjust the frequency of CLK
executing the command “setfreq xx xx (where xx is the value)” so that the
reading of the frequency counter is 10.368000 MHz ± 5 Hz.
