headphones). If you do not hear the slight threshold hum, the SENSITIVITY is low. Correct this by pushing
the SENSITIVITY "HIGH" (+) touchpad one or more times until you barely hear the threshold sound. If the
threshold sound is louder than the slight hum, push the SENSITIVITY "LOW" (-) touchpad until the correct
threshold level is achieved. Whenever the threshold level is adjusted, by pushing the SENSITIVITY LOW (-)
or HIGH (+), THE SENSITIVITY indicator will momentarily move one number down for LOW (-) or one
number up for HIGH (+). After the adjustment is registered the indicator will return and remain at number
Now you should be able to sweep the coil and notice metals are being detected when the volume increases. If
the unit is not reacting properly, try pushing the SMART TRAC touchpad a couple of times or check that the
batteries are connected and make sure they are not low. Note: Once you've adjusted for ground conditions, the
settings will not change until the unit is turned off--going back and forth from DISC TARGET will not
change your settings or ground conditions adjustment in the ALL METALS mode.
If the actual ground conditions change, that is, if you move from low mineralized ground to highly
mineralized ground (or vice versa), without having turned the unit off, the automatic feature of the SMART
TRAC will adjust for the difference. There will be a momentary change in threshold hum while the SMART
TRAC is adjusting. It is important to not make SENSITIVITY adjustments at this time. SENSITIVITY
adjustments should only be made when the GROUND MONITOR is reading "0". Merely wait a few seconds
and the threshold hum will return to normal. If after about 10 seconds the threshold hum does not return to
normal, then push the SMART TRAC touchpad for an instant Ground Balance update. If the threshold hum
does not return to normal after pushing the SMART TRAC touchpad, and the GROUND MONITOR is
reading "0", it is then possible that a SENSITIVITY adjustment is necessary.
When searching in the ALL METAL SMART TRAC mode, it is important that you allow the detector's
SMART TRAC system to properly balance the unit for mineralization. Do not start sweeping the coil until
the LCD emits the "rY" signal. The following tips may assist you when operating in the ALL METALS
1. As stated above, begin with the searchcoil about waist-high in the air when turning the Time Ranger on.
You'll notice the "Ar" indication on the LCD as soon as you turn the unit on. "Ar" stands for air and lets you
know that it is in the process of measuring the air. This allows the SMART TRAC system to measure the air
before the coil is lowered to the ground. As soon as the blinking arrow comes up under "IRON/FOIL" a "dI"
appears where the "Ar" was. This lets you know that the unit is now ready for Mode Selection.
2. Lower the searchcoil to the ground and push the ALL METAL SMART TRAC touchpad. "Gb" will now
appear on the display, then change rapidly to reference numbers. Wait until the number values change into an
"rY" indication. This lets you know that the ground measurements were taken and the unit is now ready to be
operated in the ALL METALS mode.
3. If you're getting a constant signal, try moving the searchcoil to a different area and again push the ALL
METAL SMART TRAC touchpad in case metal is setting the unit off. If not, try decreasing the
SENSITIVITY by pushing the minus (-) touchpad until you've achieved the desired level.
NOTE: always be careful that there is no metal on top of or under the ground where you will be ground
balancing, otherwise you will not be able to determine if the tone being emitted is caused by mineralization or
metal. If you think you might be over metal, move to another spot and follow the procedure outlined again.
Observe your GROUND MONITOR carefully when moving the searchcoil to a new position.
4. If the detector has too much hum, push the minus (-) touchpad under SENSITIVITY. You'll notice that the
"SENSITIVITY" dial arrow on the LCD display will jump to the "4" indication momentarily and bounce back
