(Caution) Restric tions on functions common to CH 0/CH1
* When t he FS K detector (FS K , DE T ) is used, it is prohibited to use DTMF detec tor
0 (DTMFDE T 0) or DTMF detec tor 1 (DTMFDE T 1).
* When the DP GE N is used, it is prohibited to use the FS K generation function and
tone generation function of either channel .
(Caution)
A function whose use is prohibited or a function with restrictions is indicated by
the following s ymbol .
