2795 Data Entry as Assembled in the 2715 TCU
the entry request lever remains in the latched position; and
the card or badge cannot be removed from the reader. This
signals the operator that retransmission of the record is
required. The operator resets the terminal by pressing the
error indicator/reset button. The indicator/reset button is
also used to reset the terminal whenever a reset is required.
Entry Request Lever
Pushing down the entry request lever initiates a request to
the area station for service and furnishes the motive power
required to read the information entered by the operator.
The operator initiates the request for service by positioning
the lever in the latched position, which is indicated by
"green" in the entry flag window.
The request lever cannot be fully positioned if the card or
badge is improperly registered. When the request lever is
latched in the request position, the card or badge cannot be
removed from the machine. When the complete transaction
has been received by the system controller, the request lever
is returned automatically to its start position and the entry
flag is returned to its black position (ready for the next
entry).

2796 D A T A E N T R Y U N IT
The 2796 contains all of the features of the 2795 plus three
additional features:
Rotary Switches. Two additional ten-position rotary
switches are provided, for a total of four switches.
Rocker-Thumbwheel Switches. Four rocker-thumbwheel
switches located on the front cover permit manual entry of
four digits of numeric data.
Monitor Key. The monitor key located on the left cover
allows a key holder to add an approval to a given transaction.
Approval is accomplished through the transmission of a
unique character that is activated by using a key in a
three-position lock switch. The key must be returned to
the center position to be removed. With the lock turned
clockwise, a 1 is transmitted; in the center, a 2 is trans
mitted; and turned counterclockwise, a 3 is transmitted.
