INITIAL
TESTS
The
following resistance tests
will
help
assure
you
that there are no
wiring errors or other problems that
might
prevent your unit from operating
properly,
or
even damage
components. You will need an ohmme-
ter to
make these tests.
If
you do
not
achieve the indicated
results as you
perform a test, locate
and correct the problem
before
you proceed to the next
test. A possible cause is
listed for each
test. Refer to the "In
Case of Diffi-
culty"
section for help in locating
more
difficult
problems.
RESISTANCE
TESTS
The following resistance
tests will help
determine
if
there are any wiring errors, solder

other
problems in your Transceiver.
Perform
all of the
tests before
you connect your Transceiver
to a power
source.
Set the front panel
controls and switches as follows:
(
)
BAND switch
-
80.
(
)
SELECTIVITY
-
WIDE.
{
)
Set your ohmmeter to
the R
x
100 range and
connect its common lead
to the Transceiver
chassis.
(
)
CW
LEVEL
-
fully counterclockwise.
(
)
RIT
-
center of rotation (detent position).
(
)
AF GAIN
-
fully
counterclockwise (off).
NOTE: If
you do not obtain
the correct meter read-
ings in the
next step, interchange
the meter leads
and
recheck
the readings.
