Selectors 1 through 4: Tone signal transmission time length and Min. pause in tone dialing
These selectors set the tone signal transmission time length and minimum pause in tone
dialing.
(Example: If "1," "2," "3," "4," and "5" are dialed.)
l
Selectors 5 through 8: Attenuator for pseudo ring backtone to the line
These selectors are used to adjust the sound level of beep generated as a ring backtone in
the F/T mode or as a signal during remote control operation or at the start of ICM recording.
Setting two or more selectors to "1" produces addition of attenuation assigned to each
selector.
