4. BASIC OPERATION AND DESCRIPTION 4.1 Power On/Off Switches Press “ON” once to activate the locator circuitry. Press “OFF” once to turn the battery power off. 4.2 Volume and Sensitivity Control Knobs Rotate the volume knob to the desired audio volume level. Full volume is achieved when the knob is turned fully clockwise.
5. BATTERY REPLACEMENT The LCD will display a flashing “Low Battery” warning when the batteries fall below a predetermined voltage level, alerting you to replace the batteries soon. Several hours of battery life remain; however, in cold temperatures, this time may be shorter. Replace the batteries as follows: Turn the power off.
6. FIELD OPERATION The recommended search position is a 45° angle from the earth’s surface. Scan the locator pole from side-to-side in a slow sweeping motion while walking in a steady direction. Maintain a consistent height above the ground during the side-to-side sweeping motion.
6.1 Water Locations The pole section of the locator can be submerged into water, up to just under the plastic case (Fig. 3). Fig. 3 6.2 Locating Near a Steel Fence Move or slide the locator across the ground while holding the length of the locator body perpendicular to the fence.
7. SIGNAL RESPONSE Figure 5 shows audio and LCD visual signal response to: 1: no object, 2: one small deeper metal target, and 3: a second larger and shallower metal object. The LCD display indicates both the numeric digital and analog bar-graph response as the locator passes over the ground.
7.1 Typical Signal Responses The metal handles on the septic tank cover Signal Response will provide a usable signal to determine the location of the actual cover (Fig. 6). Fig. 6 Large metal objects may cause double Signal Response signals as indicated (Fig.
