The keys
in
the top row of the screen keyboard represent the
function keys
on
the
XE
console and the [Help] key
on
the key-
board. The
letter
on
each key
on
screen
is
the first letter
in
the
name of the key it represents. From left to right the keys
on
screen are [Help], [Start], [Select], [Option], and [Reset].
You
will not be able to test the [Help], [Reset],
or
[Break] keys .
Press ing [Help] returns you to the Self Test menu; pressing
[Reset] returns you to Missile Command or BASIC (if you have
a keyboard attached); and [Break] doesn
't
function in the test.
Note: If you do not have a keyboard connected to your system,
you can test
only the [Start], [Select], and [Option] keys with
the keyboard test.
All Tests
When you select the ALL
TESTS
option from the Self Test menu,
the
XE
runs the memory test, audio-visual test, and keyboard
test
in
sequence, and continues running them until you press
[Reset] .
In
Case of Problems
If you
run
into problems operating your
XE
game system, don 't
panic. Chances are the
difficulty is something you can take
care of
yourself.
The Picture Doesn't
Look
Right
If the image
on
your video display screen doesn 't look
right-if
it's fuzzy, distorted, flickering , if no screen image appears, or
if you see a
li
ght-grey
screen-check
these areas:
• Power Switches Make sure both the
XE
console and the
video display are turned
on.
• Switch
Box
If you '
re
us
i
ng
a
TV
, set the switch box to
the COMPUTER position .
• Cable Connections Test the cable connections to see if
they are correct and secure.
If you're using a
TV,
make
sure the
TV
cable is properly plugged
in
to the switch box
and
console, and the switch box and antenna cable con-
nections are
correctly and securely attached.
•
TV
Channel If you '
re
using a
TV
, the channel selectors
on
both the
TV
and the back of the
XE
console should be
set to the same channel (2 or 3, whichever
is
weaker
in
your area). If a strong
TV
signal is broadcasting
on
the
channel you selected, you 'll experience interference. Try
selecting the other channel (2 if you '
re
on
3 and 3 if you're
on
2)
on
both the
TV
and the
XE
console channel selectors.
