Discovery3 Metal Detector (630-3008) Assembly Faxback Doc. # 17723 Assembling your Discovery3 Metal Detector is easy and requires no special tools. Just follow these steps: 1. Using the supplied bolt and nut with knobs, attach the searchcoil to the lower stem. 2. Press the button on the upper end of the lower stem and slide the lower stem into the upper stem. Adjust the stem to a length that lets you maintain a comfortable upright posture, with your arm relaxed at your side and the searchcoil level to, and about 1/2 to 2 inches above the ground. 3. Wind the searchcoil cable around the stem. Leave enough slack in the cable to let you adjust the coil when you are hunting on uneven ground. Then tighten the knob at the end of the searchcoil. NOTE: To adjust the coil, simply loosen the knob. 4. Insert the coil's plug into the matching connector on the control housing. Be sure the holes and pins line up correctly. CAUTIONS: Do not force the plug or you might damage it. To disconnect the cable, pull out the plug. Do not pull on the cable. INSTALLING THE BATTERIES Your metal detector requires two 9-volt alkaline batteries, such as Radio Shack Cat. No. 23-553. Follow these steps to install the batteries. 1. Press the battery compartment covers in the direction of the arrows. 2. Snap one battery onto each of the terminals, and place the batteries inside the compartments. 3. Replace the compartment covers. CAUTION: Only use fresh batteries of the required size and type. NOTES: The low battery indicator lights briefly when you turn on power, so you know the detector is working properly and the batteries are good. If the low battery indicator stays on continuously, replace the batteries. Many metal detector problems are caused by weak, dead, or improperly connected batteries. If the detector does not come on, has weak volume, will not tune properly, has erratic operation, or drifts, replace the batteries. You can extend battery life by using headphones. Remove the batteries if you do not plan to use the detector for a week or more. USING HEADPHONES Using headphones (not supplied) with your metal detector makes it easier to identify subtle changes in the threshold levels for better detection results, and also reduces drain on the batteries. The detector has a stereo headphone jack. For the best sound, use stereo headphones (such as Cat. No. 33-1029 or 33-1125). To connect headphones, insert the headphones' 1/4-inch plug into the headphone jack on the side of the detector's control housing. Listening Safely To protect your hearing, follow these guidelines when you use headphones. Set the volume to the lowest setting before you begin listening. After you begin 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 damage your hearing. Traffic Safety Do not wear headphones while operating your detector in traffic areas. This can create a traffic hazard and is illegal in some areas. Even though some headphones are designed to let you hear some outside sounds when listening at normal volume levels, they still present a traffic hazard. (JC/all-11/02/95)
