Uniden Clock - Manual (Page 22)

Symptom Possible Reasons Suggested Solutions
Unit is not reading prop-
erly at high speeds,
causing high random
numbers at high RPM
.
There are three basic
types of installations:
Inside-the-Hull,
Through-the-Hull, and
Transom Mount. Gen-
erally, this situation is
attributed to the location
and installation of the
transducer. A great
deal of air is flowing
over the face of the
transducer and is inhib-
iting the unit from re-
ceiving the correct
bottom reading.
Cavitation (locked on
bubbles) either on the
face of the transducer or
on the underbelly of the
boat is preventing the
unit from displaying the
true depth.
Refer to the pages in
this manual along with
the drawings for your
particular boat on the
proper installation tech-
nique.
If this is a Transom
Mount Transducer, it
may require that the
transducer be adjusted
lower in the bracket so
that it extends further
under the bottom of the
boat and is allowed a
clean flow of water.
It could also require that
the transducer and/or
bracket be relocated to
achieve a clean, smooth
flow of water over the
face of the transducer.
Transom Mount Trans-
ducer
is breaking where
the mounting bracket at-
taches to the trans-
ducer.
This occurs if the trans-
ducer is installed under
a gasoline overflow vent
OR if an adhesive such
as LOCKTITE® was
used to bond the hard-
ware onto the trans-
ducer mounting bracket. Transducer may be per-
manently damaged and
is non repairable. Be-
fore installing a replace-
ment -transducer, be
sure to move the
bracket.
The adhesive or gaso-
line has eaten into the
plastic and cannot be
repaired.
A30 or A00 reads out
permanently on the dis-
play. A lug from a transducer
wire was accidentally
connected to either the
Alarm Up/Down terminal
and power was applied. Unfortunately, perma-
nent damage has been
done to the main sur-
face mount “chip”. The
instrument head only
must be returned for re-
pair.
