Syntax: f1=val,f2=val[,c=on1/off1[-on2/off2[-on3/off3]]];

 

 

 

 

 

(Frequencies are in Hz and cadence on and off are in 10ms)

 

 

 

 

 

ON is the period of ringing (“On time” in ‘ms’) while OFF is the period of silence. In order

 

 

 

 

to set a continuous ring, OFF should be zero. Otherwise it will ring ON ms and a pause

 

 

 

 

of OFF ms and then repeat the pattern. Up to three cadences are supported.
