I
Stand-Alone Test
This test checks the transmit and receive capabili-
ties
of
the COM1serial communicationport; it also
checks terminal functions in
the communication
mode.
With all communication cables disonnected, con-
nect a jumper from pin
2 to pin 3
of
the COMI
port.
NOTE:
A wire paper clip can
be
easily bent
so its ends will fit into the COM1 connector.
As viewed from the rear of the terminal, pins
2 and 3 are the second and third from the
right, on the top row.
Make sure the power cord is properly connected
to the terminal and plugged into a live wall recep-
tacle. Power up the terminal by pressing the
POWER switch (Figure 1-1); listen for a beep
sound.
NOTE:
Lack of a beep sound
may'
indicate
a power supply or logic board failure, and
require service.
After the beep sounds, the terminal should be in
the communication mode. The cursor should ap-
pearin the upperleftcorner
of
the screen. A status
line may be just above the cursor.
For those users not displaying a status line, check
the COMMMODE
in
the GENERAL setup menu.
The option selected should be FULL DUPLEX,
HALF DUPLEX,
or
BLOCK. Enter several key-
strokes and observe the screen.
In full duplex mode, each character should be
displayed as typed.
In half duplex mode, each character you type will
be repeated on the screen. Forexample,
if
you type
an "a," the screen will display "aa."
If You Need Assistance
Your dealer can help you solve problems and
obtain service. Before calling your dealer, review
the troubleshooting checklist in this chapter and
check the operating parameters (turn to Chapter 2
to review them). Try to place the ternlinal
by
the
TROUBLESHOOTING

phone. Have the terminal serial number, found on
the rear
of
the case, and this manual at hand.
The terminal is covered
by
a limited warranty,
which should be packed with the terminal (see your
dealer
if
by
chance it was omitted from your pack-
age). No warranty registration is required.
If
you need serviceduring the warranty period,call
your dealer.
Should you need
to ship the terminal for repair, ask
your dealer
to secure a Return Material Authori-
zation (RMA) number. Terminals are not accepted
for repair without an RMA number. Thencarefully
pack the terminal, using either the original ship-
ping container
or
other suitable materials.
ICAUTION I
If returning the terminal for a commu-
nication failure,
have
your
system
ports and cables checked. A miswired
or short circuited system could dam-
age a newly repaired terminal.
