Selectors 1 through 3: Dial tone/busy tone detection level during recording of ICM (Not used.)
If the machine (called station) detects dial tone (400 Hz continuously) or busy tone (400 Hz
intermittently) exceeding the detection level specified by these selectors for the period specified by
selectors 1 through 4 on WSW35, then it interprets the calling station as being disconnected. The
machine stops TAD recording and disconnects the line.
Selectors 8: Text copy density adjustment
This function is used when a copied image of a dark document is still light even if adjusting using
the contrast adjustment for the user operation.
