3.2.3 Insert 2 new batteries into the
BATTERY COMPARTMENT.
Cares
should be taken for the polarities
symbols (+ and -) which are marked
the connection terminals and on the
batteries.
The polarities of the
battery must be matched with the
polarities of the terminals.
Cautions:
Use only fresh batteries and always
replace the old batteries by fresh
batteries.
Do not mix old and new batteries,
different types of batteries (standard,
a l k a l i n e , o r r e c h a r g e a b l e ) , o r
rechargeable batteries of different
capacities.
Never attempt to recharge the non-
chargeable battery. 6F22 or S006P 9-
v o l t b a t t e r y i s n o r m a l l y n o n -
rechargeable.
Dispose old batteries promptly and
properly.
3.2.4 Replace the battery cover.
3.3 BATTERY TESTING
Note:
The batteries should be tested after
initial batteries installation.
The
batteries should also be tested if the
detector does not turn on, has weak
volume, cannot tune properly, or drifts
or has erratic operation.
You are recommended to test the
batteries every time you use your
detector.
To test the batteries, turn the DISC-
rimination dial clockwise (at any
position). Then set the SENS-itivity
dial anti-clockwise until a click sound
is heard. A loud tone indicates good
batteries. A faint tone indicates weak
batteries and no tone means that it's
time to change.
3.4 USING HEADPHONE
You should always use a headphone
whenever you search with your metal
detector.
Headphone is especially
useful in noisy area, such as the
beach and rear city area. It enhances
audio perception by bringing the
sound directly to your ears while
masking "outside" noise interference.
You shall be amazed at how much
better you can hear the detector
signals with the headphone than you
can with the speaker alone. Using
headphones also save battery power.
To connect a headphone to the
detector, insert the headphones' 1/8
inch plug into the HEADPHONE JACK
(8).
Note:
The detector's internal speaker will be
disconnected when you connect a
headphone.
