2.2.
Power
on
The
hand
held
metal
detector
has
a
power
switch
with
three
positions
(see
callout
10
on
Image
2.1.
and
Table
2.1.a).
The
center
position
will
turn
OFF
the
power
to
the
device.
The
UP
position
(towards
the
front
of
the
wand)
will
turn
the
device
on,
and
will
enable
only
the
vibration.
The
DOWN
position
(towards
the
bottom
of
the
wand)
will
turn
the
device
on,
and
will
enable
only
the
sound
alarm.
When
the
device
is
on,
the
green
LED
will
turn
on
and
will
blink
(callout
8),
and
will
stay
on
(blink)
until
device
is
turned
off.
If
the
power
LED
does
not
turn
green,
or
there
is
a
continuous
sound
or
vibration,
the
battery
is
depleted
and
needs
to
be
replaced.
Replace
or
recharge
the
battery
and
then
try
again.
You
can
also
check
the
low
battery
indicator
(see
callout
2).
If
the
LED
is
yellow,
replace
the
battery.
2.3.
Detection
and
sensitivity
scanning
Once
the
power
is
turned
on,
and
the
device
is
set
to
vibration
or
audio
alarm,
use
the
detection
area
of
the
metal
detector
(callout
1).
If
metal
is
detected,
the
wand
will
vibrate
or
make
a
sound.
There
are
also
two
visual
indicators:
a
red
LED
(callout
3)
and
a
signal
strength
indicator
(callout
6).
These
will
automatically
turn
on
once
metal
is
detected.
The
High
sensitivity
can
be
used
in
day
to
day
operations.
In
special
cases,
the
Low
sensitivity
can
be
used.
Use
the
sensitivity
button
(callout
9)
to
reduce
the
wand
sensitivity
in
a
ratio
of
1:5
(sensitivity
will
be
reduced
five
times).
This
is
recommended
when
the
area
of
interest
is
surrounded
my
metal
objects
that
could
trigger
an
alarm.
2.4.
Powering
and
charging
the
device
The
handheld
metal
detector
has
three
ways
of
operation:
battery,
rechargeable
battery
and
powered
operation.
No
batteries
are
supplied
with
the
unit.
The
unit
operates
with
9V
(or
E)
size
batteries.
Before
battery
installation,
observe
the
battery
polarity.
The
battery
socket
is
marked
with
Positive
(+)
and
Negative
(
‐
)
symbols.
When
used
with
non
‐
rechargeable
batteries,
do
not
connect
the
unit
to
the
120Vac
[220Vac]
charger.
This
can
cause
a
fire
or
explosion.
When
used
with
rechargeable
batteries,
the
yellow
LED
(see
callout
2)
will
indicate
when
battery
is
running
low.
Connect
the
unit
to
the
charger
using
the
power
jack
(see
callout
4).
Recharging
time
depends
on
the
selected
battery
capacity.
When
used
continuously,
connect
charger
to
the
unit.
