This machine will delay the start of detection for no tone by the length of time set by selectors 1 and 2. The sum of the detection delay time setting and the waiting time for no-tone detection setting by selectors 1 through 5 of WSW21 must be within 40 seconds or less. • Selectors 3 and 4: External TAD no-tone detection level These selectors set the no-tone detection level in the external TAD mode.
