NOTE: Selectors 1 through 4 are applicable to those models equipped with a built-in TAD.

•Selectors 1 through 4: Detection time length of the disconnection tone in ICM recording

If the equipment detects disconnection tone for the time length set by these selectors, it will disconnect the line.

•Selectors 6 through 8: Lower limit of frequency to be ignored after detection of calling signals (Ci)

At the start of reception, if the equipment detects the frequency of calling signals (Ci) specified by selectors 1 through 4 of WSW14, it will start the ringer sounding. When doing so, the equipment may fail to detect the calling signals normally due to noises superimposed at the time of reception. To prevent it, use selectors 6 through 8 of WSW36.

If the equipment detects higher frequencies than the lower limit specified by these selectors, it will regard them as noise and interpret that detecting state as being normal, allowing the ringer to keep sounding (until the equipment starts automatic reception of FAX data if in the FAX mode or enters the TAD mode if set in the TEL mode, according to the preset number of ringers).
