(H)* BBIC Clock Adjustment

CLK

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 ± 20 Hz).
4. If the frequency is not 10.368 MHz ± 20 Hz, adjust the frequency of CLK

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.

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.
