UNPACKING
If damage has occurred in shipment, file a claim with the carrier immediately. If it is necessary to contact your supplier or manufacturer concerning damaged or missing items, be sure to include all information such as serial number, purchase order number and invoice number. This will assure you of obtaining proper and expeditious service.
PRELIMINARY
Loosen the adjusting collar on the telescoping stem, and extend the stem until it is long enough so that, when the Detector is held in a comfortable position, the search head is as close as possible to the ground. Tightening the adjusting collar will lock the stem in the desired position.
Please note that the inner portion of the telescoping stem is free to rotate through 1/4 of a turn. This permits the head to be turned sideways for compact storage, but prevents it from twisting far enough to damage the wiring inside the stem. No attempt should be made to twist the stem past the point where it stops.
TUNING
IMPORTANT! Read carefully and follow instructions precisely!
This Detectron Valve & Box Locator, must be tuned at the same level at which it is operated. If change in the operating level is necessary, the instrument must be “ReTuned” at the higher or lower operating level. The correct operating position is when the detection head is in the exact same plane as the surface over which it is being used. For maximum results, keep the detection head very close to the surface under investigation.
For proper “TUNING” follow the steps listed below in sequence:

PRODUCT INSTRUCTIONS
1.Turn instrument on.
2.Hold the instrument in the operating position, keeping in mind that the detection head should be close to the ground surface and maintained in this position throughout the tuning and operating of the Detector.
3.Turn the tuning knob (located below the meter) to the left until it stops, be careful not to force it.
4.Now turn the tuning knob to the right until you find a point where there is no tone coming from the loudspeaker and the meter reads “ZERO”.
5.Continue turning the knob slowly to the right until the tone reappears and the meter needle responds.
6.Now carefully turn the tuning knob to the left very slowly until the tone just disappears and the meter reads “ZERO”.
7.To check for proper tuning and maximum sensitivity, raise the instrument a few inches from the position in which you carried out Steps 1 through 6. If the tone sounds when the instrument is raised, it was properly tuned at the lower level and it can be assumed that maximum sensitivity has been obtained.
OPERATING PROCEDURES
After completing the proper tuning your instrument is ready to use. The instrument is designed to afford the operator ease of handling at a comfortable walking position passing the detector head from side to side in front of the operator allows a rather wide area to be covered on a single pass. Provided the instrument is properly tuned, it will indicate metallic objects when the detecting head is passed directly over them. To pinpoint such an object, simply approach it from several directions and investigate in the center of the area over which you obtained the signal indications.
It is suggested that preliminary operation of the Detector be carried out over known metal objects of various sizes. This will help you to become familiar with the operation of the instrument and will greatly increase your ability to find objects whose locations are unknown. Trial operation will also increase your ability to tune the instrument to its maximum sensitivity, which is important when attempting to locate smaller metallic objects.
SPECIAL OPERATING PROCEDURES
There are many variations to the operation of your Valve & Box Locator, but basically they are alike. For instance, should you desire to operate your instrument over ground
