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.
If selector 8 on WSW23 is set to "0," this setting is so limited that 10 dB (1 dB in France) or
higher setting only is effective. Note that in Japan and China, 9 dB or higher and 2 dB or higher
settings only are effective, respectively, regardless of whether selector 8 on WSW23 is set to "0."
