These selectors set the period required to make the machine acknowledge itself to be called. That is,
if the machine continuously detects a CI signal with the frequency set by selectors 1 through 4 on
WSW14 during the period set by these selectors 5 and 6, then it acknowledges the call.

The modem should be adjusted according to the user's line conditions.
• Selectors 1 and 2: Cable equalizer
These selectors are used to improve the pass-band characteristics of analogue signals on a line.
(Attenuation in the high-band frequency is greater than in the low-band frequency.)
Set these selectors according to the distance from the telephone switchboard to the machine.
• Selectors 3 and 4: Reception level
These selectors set the optimum receive signal level.
• Selectors 5 through 8: Modem attenuator
These selectors are used to adjust the transmitting level attenuation of the modem when the reception
level at the remote station is improper due to line loss. This function applies for G3 protocol signals.
Setting two or more selectors to "1" produces addition of attenuation assigned to each selector.
