BATTERY REPLACEMENT
The Lobo has an automatic battery test sequence with each initial power turn on. To check the batteries, simply turn the
Lobo off for about five seconds, and then turn it back on. The battery test circuit will engage for about 3 to 5 seconds, with the
audio output loudness indicating the remaining battery strength. As the batteries age, this tone will get quieter, and when you
hear only a brief buzz or no output at all, it's time to replace the batteries.
To replace the batteries, pull the large knobs on the battery door on the rear of the unit. The entire door will pop out.
Remove the battery packs from the detector, and then remove the batteries from the packs. Replace the new penlight
batteries into the packs, observing the polarity indicators that are embossed into the insides of the packs. Slide the packs
back into the detector, making sure that the battery clip lead is connected to the packs. Install the battery door back onto the
chassis, and push the nylon fasteners into the holes on the chassis, making sure that the plungers are still pulled out. Then
push the plungers back in to lock the door in place.
Should you desire to do so, rechargeable Nickel Cadmium batteries can be substituted for standard penlight cells.
Individual AA size cells are readily available at most electronic supply stores, as well as the chargers for them, and they can
be inserted into the standard 8 holder used in your Inca. The initial battery check reading will be slightly lower, but will not
drop as much with use, until the batteries are completely discharged.
GENERAL CARE AND USE
If the detector is to be stored for a long period of time, it is best to remove the battery pack from the detector. This will
prevent internal damage to the detector if the batteries should leak.
The searchcoil is waterproof and may be submerged in either fresh or salt water. Caution should be exercised to prevent
water from entering the chassis, where it could damage the electronic circuitry. After the coil is used in salt water, the coil
and lower stem assembly should be rinsed well with fresh water to prevent corrosion of the metal parts.
There are several good books to help the beginner learn how to use the detector, where to search and how to recover a
target without damaging the environment. A good coin shooter can recover a lot of finds and leave the area looking as though
he had never been there. Above all, always fill your holes when you have recovered the target.
TESORO Metal Detectors are sold through independent dealers, who are almost always treasure hunters themselves.
They can provide you with you much needed information about how to use your detector, how to probe, plug and dig in your
locale, and answer most of your questions about treasure hunting in general.
The use of earphones will benefit you in two ways. Most earphones will very effectively block out most of the ambient
noise, such as traffic noise and wind noise, which will enable you to better hear the fainter signals caused by the deeper
targets. Obviously, the older, more valuable coins will probably be deeper than the ones which were lost last week, so you
should take advantage of anything that will help you hear the weaker signals. Secondly, using earphones will greatly extend
the battery life, since it takes much less power to operate them. The detector is not equipped with a volume control, but does
have a limiting circuit in the earphone jack. If less volume is desired with earphones, you may want to use earphones with a
built in volume control. Any good 8 or 16 ohm set with 1/4 inch stereo jack will do.
HAPPY HUNTING, and thank you for purchasing a TESORO.
