[. . . ] It is therefore necessary to ADJUST the GAIN to give you the maximum allowable GAIN without masking targets or overloading the circuit and at the same time allowing you to operate the detector with a constant faint threshold hum so that faint signals (deep or small targets) can be detected. This is where the new APOLLO 2 can help you out. When ground mineralization is too high for the current GAIN control setting, the display indicates "OVERLOAD-REDUCE GAIN/LIFT LOOP" along with an audible "squawk". Reduce the GAIN till the overload warning ceases. On occasion, while searching, you might sweep the loop over a very large or very shallow target. The message on the LCD display will read "OVERLOAD-REDUCE GAIN/LIFT LOOP". All such targets should be checked by sweeping the loop a little higher over the area and noting the display and audio indications. The APOLLO 2 will self correct after the message and you can continue to search as normal. GAIN Control Gain Adjustment 1. The GAIN control knob turns the APOLLO 2 ON and OFF and controls the GAIN. Starting from the POWER OFF position and going clockwise, the power is turned ON and the dial increases the GAIN from a minimum level of "1" to a maximum level of "+3". Set the control to the "Initial Setting Triangle" ( between level 9 & 10 ). even though the audio discriminator will signal with a reject (suppressed or broken) sound. Nickels and some jewelry will also be rejected with DISC settings much greater than "P". The "P" position is recommended for most MODES. If when searching at the "P" position you feel you are digging too much trash, adjust DISC slightly clockwise and try again. Finding the lowest (furthest counterclockwise) position that eliminates the common trash metals in your area is important in order to find items of jewelry. The APOLLO 2 provides six significantly different DISC (Discrimination) modes. In the Coin & Jewelry MODE with the Trigger on the hand grip in the center position B. And in the Relic MODE with the Trigger in the forward position (with the DISC control set for typical trash rejection). DUAL CONTROL DISC -DISCRIMINATION (outer ring) When in COIN & JEWELRY and RELIC MODE VARIABLE SELF ADJUSTING THRESHOLD SPEED (SAT) When in Prospecting MODE. 20 Chapter 5 APOLLO 2 Controls Chapter 5 APOLLO 2 Controls When a trash metal is being rejected in a Traditional DISC MODE, it will produce no beep at all or a suppressed beep that is shorter sounding typically inconsistent, a click or flutter-sounding beep. When a valuable metal is accepted it will produce a consistent, smooth, solid, and longer sounding beep. When operating below Threshold "silent search" very deep or small targets may appear as mere threshold level responses. Some large trash metals, such as pieces of lead, pot metal, aluminum, tin, brass, copper, or significant iron will produce a good sound regardless of the DISC control position.

There may be a quick, simple fix or explanation that will prevent having to send the detector in for service. Double check the obvious, such as batteries, and try the detector in another area to be sure there is not interference. Be sure to send all necessary parts with your detector, such as search coil, batteries and holders, as these items can result in symptoms. [. . . ]
