Battery Low Confirma-
tion
-
1. Apply 2.40 V between BATT+ and BATT-.
2. Confirm that there is no flashing of Battery Icon.

1. Apply 2.6 V between BATT+ and BATT- with DC power.
2. Input Command “SFR”, then you can confirm the current value.
3. Check X’tal Frequency. (13.824 MHz ± 15 Hz).
4. If the frequency is not 13.824 MHz ± 15 Hz, adjust the frequency of CLK exe-
cuting the command “SFR xx xx (where xx is the value)” so that the reading of
the frequency counter is 13.824 MHz ± 15 Hz.
Note:
Clear the registered information for CS before measurement, because the Fre-
quency will not possibly get stable due to the registered information.
Pressing the button of “3” ”5” “7” “#” clears the registration.
Register to it on CS after measurement.
