These codes are memorized, independtly from the mode or operating code. For example one of these

code can be sent in Handset mode and when the Error Beep code is sent, the square wave frequency

sent on the earphone is the one previously programmed in the Handset mode.

Note : It is possible to program n from 1 to 15, 1.0.0.0.0.0.0 to 1.0.0.1.1.1.1, the frequency values are not given in the previous table, but

can be calculated in the same way.
