washed periodically with mild
soapy water to remove any accu-
mulated road
grime or oily film.
This is essential to have good
contact between the transducer
and the water.
Periodically,
the rubber roller on
the paper
drive should be cleaned
with a cloth
dampened with alco-
hol to improve the friction on the
metering roller drive.
Don't open the case or the
transport assembly
when the unit
is running. The stylus holder and
stylus may
be damaged or per-
sonal injury may result.
TROUBLESHOOTING
ADVANCED OPERATION
Surface Clarity Control (SCC)
The surface markings at the top
of
the chart paper
can, at times,
extend many
feet below the
surface. This often interferes with
fish signals or other
targets. This
is called Surface Clutter and is
caused by algae and plankton, air
bubbles caused by wave action or
boat wakes, bait fish, or
temperature inversions.
The surface clutter
markings
can be reduced or eliminated by
using the SOC control key on the
front
panel keyboard.
To use the 3CC, press key 1
thru 7 (depending upon the
amount of 3CC desired) and then
the SCC
key. 1 has a minimum
effect on surface clutter, 7 has the
maximum effect on reducing
surface clutter. 2 thru 6 have
intermediate effects. The amount
of SCC that is used is printed at
the bottom of the chart paper. If
one level of SCC is used, then
3CC-i is printed. Two levels,
SCC-2, etc.

If you do not recognize some of
the functions listed above, look in
the Advanced Operation section of
this manual for more instructions.
The
Memory function can be
turned on or off as desired. When
the Memory function is turned off,
only the depth mode (Feet,
Fathoms, or Meters) will be
retained.
To turn the Memory function off,
press ii -2nd-5.
To turn the Memory function on,
press 10- 2nd -5.
FEET, FATHOMS,
METERS
The X-i 6 will display the depth
in feet, fathoms, or meters.
Although the unit will revert back
to the feet mode whenever the
2nd - MARK feature is used
(see
above), it is simple to change to
any mode you wish by pressing
the 2nd key and then 1 for
feet,
2nd - 2 for fathoms, and 2nd - 3
for meters.
When the unit is in the Feet
mode, the letters 'PT" will be
displayed next to the lower limit
depth scale. In the Fathom mode,
the letters "FA" will be displayed,
and the letter "M" will be
displayed when the unit is in the
meters mode.

FIGURE 19
By looking at the lower limit
scale printed on the chart paper,
one can determine if the unit is in
feet (FT), fathoms (FA),
or meters
(M). The unit can be switched
from one mode to another at any
time.
END-OF-PAPER MARKER
The graph paper used in the

X-i 6 has a red line printed at the

bottom of the paper
to signify
when there is only 2 to 3 feet
before the end of the paper.
ZERO ADJUST
Occasionally, when changing
the stylus or stylus belt,
the zero
line does not print at the same
Example: Display Fathoms
Press: 2nd - 2

Symptom
On/Off switch is "ON", but the
stylus and paper
don't move
On/Off switch is "ON", have zero
mark, but no bottom signal or
echoes.
The unit works properly when
stopped or at slow
speeds, but
loses the bottom signal at high
speed, or makes heavy
black
lines.
Blank spots
in record.
Paper stops pulling.
What To Do
Check fuse; check connections at
battery for tightness and corrosion.
Be sure the transducer is plugged
into the unit and the transducer is
making contact with the water.
Transducer is improperly installed.
Read transducer installation
instructions for the correct
mounting procedure.
Stylus is "skipping" over areas of
the chart paper. Readjust stylus
according to the diagram on page
?. If this does not help, replace
stylus.
Check paper for binding or
improper tracking. Straighten the
paper and retape it squarely onto
the take-up paper core.
