[. . . ] Press the Retune button (15) every few minutes or whenever the background tone rises to an unacceptable level. You are now searching in minimal discrimination mode. The presence of a metal target will be indicated by the increasing intensity of the tone. Signals from small ferrous rubbish will be ignored. CS440MXD_Manual. indd 2 10/5/07 11:09:52 The ConTRolS AnD whAT TheY Do (14) The on/off/sensitivity control switches the machine `on' and sets the sensitivity level. [. . . ] The purpose of the Retune push-button is to keep the detector working at peak performance by maintaining the point of threshold set on the sensitivity control. For example, moving from dry ground to wet ground may cause the background tone to gradually increase to an unacceptable level. Pressing the retune button momentarily will bring the background tone to the point of threshold again. If the retune button fails to have this effect, it is probably necessary to re-set the sensitivity level. It is good detecting practice to press the retune button every few minutes or whenever you feel that that the detector may have drifted away from its sensitivity setting. Assembly: Join the two stem sections (5)(2) together. Wind the search-head lead (9) around the stem as shown in the photograph. Adjust the stem for length according to your height (it's easier on your back if you can stand up straight while detecting) and tighten the twistlock stem adjuster (6). Check that the search-head (7) is parallel to the ground when being swept in an arc and tighten (be careful not to over-tighten) the search-head retaining screw (8). (Keep these parts clean - if they become covered in mud or sand wash and dry these parts at the end of a day's detecting. Don't allow any form of lubricant onto the rubber friction washers. ) Battery: Push back the retaining clip and remove the cover (13) of the battery compartment (12). Fit a 9 volt battery (MN1604, PP3 or equivalent). There are guide strips to ensure the battery is fitted the right way round. It should slide in easily to connect with contact strips in the compartment. Remove the battery if the detector is to be stored for more than a few days. Searching Technique: Sweep the detector head from side to side in a smooth arc. Move forward at each sweep the width of the search-head (20cms). Keep the search-head as close to the ground as possible, even at the ends of the arc where there is a natural tendency for the search-head to lift. Maintain a strict search pattern so that the area being searched is completely covered. (You will be more successful if you cover a small area of ground thoroughly than if you search a large area of ground in random fashion. The CS440XD nonmotion electronic system is most suited to a careful detecting technique). When you encounter CS440MXD_Manual. indd 3 10/5/07 11:09:52 a signal, move the search-head slowly around the area. [. . . ] However, the control box should be treated with similar care as any electronic product. The search-head may be immersed in water. Stem and search-head parts should be washed with tap water and dried at the end of a day's detecting. warranty & Service The CS440XD is guaranteed free of manufacturing defects as confirmed in our written warranty document.
