network to either a telephone set plugged into the terminal
(TALK position) or to the internal modem (DATA position) •
This switch is only operational if the internal modem is
installed.
Parameter/Mode Switches
These six rocker switches are behind a protective door on
the front of the terminal. Each is labeled according to
its function. Several have not been assigned, and their
settings do not affect terminal performance. The following
paragraphs describe the remaining four switches: SOFT/LOUD,
LOOP/EXIT, KB-TP/SKIP, and TEST/SKIP.

malfunction.

Pressing RESET switch for more than
3 seconds is necessary to initiate
terminal resident diagnostics.
