After
using
your
detector
in a hostile environment (salt water, sand etc.) the
exterior
parts
of
the
casing should
be
wiped
with
a
damp
cloth,
paying
particular
attention
to
the head, and
carefully
wiped
dry.
Foreign particles
in
the
control
box
can
be removed
by
brushing carefUlly (or
with
compressed air
or
vacuum cleaner).
Salt
Damage
If
you
use
your
detector
continually
in a salty
environment,
particularly
when the
wind
is
blowing
off
the
sea,
salty air can penetrate the
control
box.
Corrosion can
occur
in
vital
parts
of
the delicate electronic
circuitry.
It
is, therefore, recommended
that
precautions such
as
covering·the
control
box
with
polythene be
taken
to
avoid damage. ,
The guarantee cannot cover such occurrences and any repairs needed because
of
salt water
or
spray
will
be
charged.
The
Use
of
Solvents
It
has
been
found
that
some types
of
solvent
used
for
cleaning
circuitry
will
in fact
melt
the plastic
covered components.
The
life
of
the
controls
may be extended
by
periodic
(100 hours
of
use)
application
of
small
quantities
of
Iight
lubricant
to
the
spindles, threads and
knob
grub
screw
('3
in
l'
or
similar household
oil
is
suitable). This operation requires
the
knobs
to
be removed.
Light
packing grease should be smeared
on
the
threads
of
the locking collar, and at the same
time,
the
head
fixing
bolt.
Do
not
store
the
detector
in a
damp
place.
If
the detector
is
to
be stored, remove
the
batteries
as
they
may leak and corrode the surrounding electronics.
Detector
Not
Opereting
(A) Check
the
condition
of
batteries.
(B) Interchange batteries and ensure connections
are
correct and secure.
Battery
life
can
vary
tremendously between makes, therefore
your
'new'
batteries may already
be
insufficiently
powerful
to
run
your
detector.
(C) Check
the
search head cable connector
is
properly
attached
to
the
control
box.
Oscillating Signal Accompanied
by
Slight Meter
Fluctuation
(A)
Caused most
often
by
outside
equipment
such
as
fluorescent lights, taXis. radios,
power
lines
and
other
metal detectors
working
nearby.
Little
can be done
to
alleviate
the
problem except
tq
find
a
new
site.
Intermittent
Sound
From
Speaker
(A) This
could
be
due
to
poor
battery
connections. Ensure
they
are
tight
and
the
batteries are
securely clipped
into
place.
(B) Radio transmission
from
passing
taxi
or
vehicle using radio
transmitter
equipment.

Before
returning
a
detector
for
repair
to
C-$cope ensure
you
have done the
following:
(A)
Read
instructions
thoroughly.
(B)
Tried
new batteries and checked procedure
outlined
above.
IC) Speak
to
local dealer
about
performance
of
the
detector.

if

with
metal detectors
in

Return

with
letter
giving details
of

1.
Do
not
interfere
with
archaeological
siteS
or
ancient monuments.
Join
your
local
archaeological society
if
you
are interested

2.
Do
not
leave a
mess.
1t
is
perfectly
simple
to
extract
a
coin
or
other
small
object
buried a
few inches under the ground
without
digging a great hole.
Use
a sharpened
trowel
or
knife
to
cut
a

or
triangle (do
not
remove
the
plug
of

entirely
from

ground);
extract
the
object. replace
the

carefully
and
even
you
will
have
