ASSEMBLY
The Discovery2 Metal Detector is
easy to assemble and requires no
special
tools.
Follow
these steps to assemble
your
metal detector.
1. Insert
the
lower
stem into the upper stem.
2. Press
the adjustment
button on the
lower
stem as
you push
the
lower stem into
the
upper stem.
The
adjustment button
clicks
into
place
as
it reaches
an adjustment
hole.
Ad-
just
the
stem of the detector to a
length
that
enables
you
to
maintain
a comfortable upright
posture. (You
should be able to
hold
the
detector with
your
arm
relaxed
at
your
side,)
As
you
adjust the
length
of the stem, keep in
mind
that the searchcoil should be approxi-
mately
llz
lo
2 inches
above the
ground.
3. After
you
set
the adjustment,
wind
the
searchcoil cable around
the
stem. Be sure
to
provide
enough slack in the cable to accom-
modate
angle adjustments.
4. Place
the searchcoil
plug (which
does the
detection) into
the
plug
connection at the
base of
the control
housing. Be sure
the
holes
and
pins
line
up correctly.
Push
the
plug
in
untilthe
plug
is
secure.
Caution: Do not force the
plug
or
you
may
damage
it.
Note: When
disassembly is required, remove
the
plug
by
pulling
at the connection
point.
THE
SEARCHCOIL
Adjust
the searchcoil so it is level with
the
ground.
Tighten
the knob at the end
of the sear-
chcoil
to keep
the searchcoil
from
rotating
or
wobbling.
The
searchcoil
is waterproof. You
can
put
it in
fresh
or
saltwater
up to the control
housing.
After
you
use the
searchcoil
in
saltwater,
rinse
it
with
fresh
water
to
prevent
corrosion of the me-
tal
parts.
INSTALLING
THE BATTERIES
Your metal detector requires
two 9-Volt
bat-
teries.
We
recommend
alkaline batteries such
as
Radio
Shack Cat. No. 23-553.
Follow
these steps to
installthe
batteries.
1. Press
the battery compartment
covers
in
the
direction of the arrows.
2.
Snap one battery
into
each of the
terminals.
Place
the batteries inside
the bailery compad-
ments.
3.
Replace
the battery compartment
covers.
Notes:
r
lf
the
Low Battery
indicator flashes momen-
tarily
when
you
turn ofi POWER,
you
know
it is
working
properly
and the batteries
are
good.
'-""tdis

.
lf the Low Battery
indicator lights
and
stays on, replace
the
batteries.
.
Approximately
90% of
metal
detector
problems
are caused
by
weak,
dead or
improperly
connected
batteries. lf
the unit does not
come
on, comes
on but
has weak volume,
will not
tune
properly,
or
has
erratic operation
or drifts, re-
place
the batteries.
.
When
you
install a fresh
set of 9-Volt
alkaline batteries,
keep
track
of
your
operating
time.
After
about
four
or five hours
of
use, switch
the batteries.
Put
the left
battery
into
the right
compartment,
and the right
battery into
the left
compartment. The
audio draws
one battery
down slightly faster
than
the oth-
er, and switching them helps insure
equal drain.
.
You
can extend battery life
by using headphones,
which require
less
power.
.
Remove
the batteries if
you
do not
plan
to use the
detector for
a
week
or
more.
USING
HEADPHONES
Using
headphones with
your
Discovery2
Metal Detector will not
only
increase
the
life of
your
batteries,
it will increase
your
ability to
identify
subtle changes
in
the
threshold tones
for
better detection
results.
To use
headphones with
your
detector,
insert
the
headphones's
1i+-inch
plug
into
the
headphone
jack
located
at the top of the control
housing. Then
proceed
with
your
search.
Hearing
Comfort and
Your Health
To
protect your
hearing,
follow
these
guidelines
when
you
use
headphones.
.
Set the volume to the
lowest
setting before
you
begin
listening. After
you
be-
gin
listening, adjust the
volume
to a comfortable
level.
.
Do not
listen
at extremely
high volume levels. Extended high-volume listening
can
lead
to
permanent
hearing loss.
.
Once
you
set
the volume, do
not
increase
it.
Over time,
your
ears adapt to the
volume level, so a volume level that does
not
cause discomfort
might
still dam-
age
your
hearing.
