Anleitung Zusammenfassung
PINPOINTING Pinpointing is the process of finding the exact location of a buried object. Long-buried metals can appear exactly like the surrounding soil, and can therefore be very hard to isolate from the soil. PULL-TABS Discarded pull-tabs from beverage containers are the most bothersome trash items for treasure hunters. They come in many different shapes and sizes. Pull-tabs can be eliminated from detection, but some other valuable objects can have a magnetic signature similar to pull-tabs, and will also be eliminated when discriminating out pull-tabs. GROUND BALANCE Ground Balancing is the ability of the detector to ignore, or "see through," the earth’s naturally occurring minerals, and only sound a tone when a metal object is detected. The Discovery 2200 incorporates proprietary Squelch-Tech® circuitry to eliminate false signals from severe ground conditions ASSEMBLY from the lower stem. .2 Press the button on the upper end of the lower stem, and slide the lower stem into the upper stem. Assembly is easy and requires no tools. .1 Position the lower stem (the straight tube) with the silver button toward the back. Using the bolt and knurled knob, attach the search coil to the plastic extension protruding Adjust the stem to a length that lets you maintain a comfortable upright posture, with your arm relaxed at your side, and the search coil parallel to the ground in front of you. .3 Wind the cable securely around the stem. .4 Insert the plug into the matching connector on the right underside of the detector body. Be sure that the key-way and pins line up correctly. Caution: Do not force the plug in. Excess force will cause damage. To disconnect the cable, pull on the plug. Do not pull on the cable. ASSEMBLY Adjusting the Arm Rest Most people will find the standard position of the arm rest very comfortable. Very large forearms and short forearms (particularly children’s arms), can be accommodated by moving the arm rest forward. The arm rest is adjustable to three positions. To adjust, remove the screw from the underside, then press the silver button and move the arm rest to one of the alternate positions. If you cannot fully depress the button with your finger, use a narrow object, such as the blunt end of a ballpoint pen. The arm rest must be twisted with moderate force to move it to an alternate position; this adjustment is usually made infrequently. If desired for added stability, re-install the screw. The screw is not re-installed in the furthest forward position. If the button becomes disengaged inside of the tube, remove the plastic cap at the end of the tube to access the clip inside. With a pair of needle-nose pliers, reengage the button. Then replace the plastic cap. SENSITIVITY DISCRIMINATION BATTERIES Use ALKALINE batteries only. To install the batteries: .1 Remove the battery cover by disengaging the clip at the back. .2 Align the polarity of the batteries correctly, with the positive "+" toward the coil plug connection, as indicated by the + and – indicators on the housing. .3 Insert (2) 9-Volt ALKALINE batteries, with the contacts pointed inward, and press down on the back of the batteries to snap them into place. Some brands of batteries will require moderate force to clear the retaining tabs. If the batteries fit loosely, and you want to guarantee a very secure electrical contact, insert a piece of paper or thin cardboard between the back of the battery and the supporting post. .4 Replace the battery door. IN CASE OF LOOSE BATTERIES The Low Battery Indicator will come on and stay on if the batteries need to be replaced. Most metal detector problems are due to improperly installed batteries, or the use of non-alkaline or discharged batteries. If the detector does not turn on, please check the batteries. If the detector does not turn on, check to see that the batteries fit tightly. If the batteries are loose, press them forward while pressing the POWER touchpad. To tighten up a loose battery, wedge a piece of paper or thin cardboard between the back of the battery and the supporting post, as illustrated above. QUICK-START DEMONSTRATION I. Supplies Needed • A Nail • A Quarter • A Pull-Tab from a beverage can • A Zinc Penny (dated after 1982) II. Position the Detector a. Place the detector on a table, with the search coil hanging over the edge. (or better, have a friend hold the detector, with the coil off the ground) b. Keep the search coil away from walls, floors, and metal objects. c. Remove watches, rings and other jewelry or metal objects from hands and wrists. d. Turn off appliances or lights that cause electromagnetic interference. e. Pivot the search coil back toward the detector body. III. Power Up Press the POWER touchpad. IV. Wave each Object over the Search Coil a.Notice a different tone for each object. Bass Tone: Nail Low Tone: Pull-Tab Medium Tone: Zinc Penny High Tone: Quarter b.Motion is required. Objects must be in motion over the search coil to be detected. V. Press the DISC A...
