*A
Under -10°C, the time required till effective data is output from DO is longer than that at normal temperature. It is
recommended to use a preamble which is twice the length of the usual preamble. Please refer to page 12.

Time required for the TX frequency or 1
data is output.
* 3
Time required for the TX frequency or 1
data for 25kHz shift is output.
