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 selec-
tor.
This setting will be limited if selector 8 of WSW23 is set to "0."
