Battery Monitor Check
-
1. Apply 2.25 V between BATT+ and BATT-.
2. Execute the command
2. Execute the command
sendchar PAD
sendchar LED 0
sendchar CRX 0 1
sendchar AD1
It assumes that the return value is XX.
a) XX: 70: No need to adjust
b) XX: 66 ~ 6F: Need to adjust
XX: 71 ~ 7A: Need to adjust
Write AD value of 2.25 V to EEPROM.
ex) read data: XX = 6A, write data: YY = 6A
read data: XX = 73, write data: YY = 73
EEPROM = 0009(Low Voltage) write “YY”
Execute the command “wreeprom 00 09 01 YY”.
EEPROM = 000A(No Voltage) write “YY -C"
Execute the command “wreeprom 00 0A 01 ZZ”.

1. Apply 2.6 V between BATT+ and BATT- with DC power.
2. Input Command “sendchar sfr”, then you can confirm the current value.
3. Check X’tal Frequency. (10.368 MHz ± 100 Hz).
4. If the frequency is not 10.368 MHz ± 100 Hz, adjust the frequency of CKM

3. Check X’tal Frequency. (10.368 MHz ± 100 Hz).
4. If the frequency is not 10.368 MHz ± 100 Hz, adjust the frequency of CKM
executing the command “sendchar sfr xx xx (where xx is the value)” so that the
reading of the frequency counter is 10.368000 MHz ± 5 Hz.
reading of the frequency counter is 10.368000 MHz ± 5 Hz.
Note:
Clear the registered information for Base Unit before measurement, because the
Frequency will not possibly get stable due to the registered information.
Pressing the button of "3" "5" "7" "#"clears the registration.
Register to it on Base Unit after measurement.
