machine selects the slower modem speed automatically.
It is effective when noises occur on the received document due to the
long distance communications.

SW-B1 No. 1 ~  No. 4 Recall interval

recalling is fixed to one time.

Supplementary explanation
If time-out termination is made when dialing, only single recall is possi-
ble even if the setting time of recalls (SW-B1 No. 5 - No. 8) has been set
to some times. This soft switch is added in order to meet FCC regula-
