Selectors 1 through 3: ON-duration of the scanning light source at room temperature (Not used.)
If the scanning operation is started when the scanning light source is off, then it will come on for
scanning. These selectors determine how long the light source is ON after scanning.
If these selectors are set to "1, 1, 1," the light source goes off immediately after the scanning
sequence.
Selectors 5 through 8: Modem attenuator
These selectors are used to adjust the transmitting level of the modem when the reception level at
the remote station is improper due to line loss. This function applies to super G3 protocol signals.
