LCD VISUAL DISPLAY (continued)
BATTERY CONDITION INDICATOR
Fresh alkaline batteries will illuminate all three bars. When no bars are displayed and the
batteries are about to go dead, the BATT legend will start flashing. The detector should
operate for about 30 minutes from the time the indicator starts flashing. If using NiMH
rechargeable batteries, the display will remain stuck on the second or third bar for most of
the battery life; when it drops to the first bar, the batteries will go dead within several
minutes.
G.B.
This is the ground balance setting, 0-99. It is displayed when in the Manual G.B. menu
setting, and when the trigger is pushed for FASTGRAB computer-assisted ground
balancing.
SETTING
This is illuminated when you are in the menu. When the word “SETTING” is indicated,
the number being displayed is a setting, and not, for instance, a Target ID indication.
MESSAGES
The small rectangular box at the bottom-center of the LCD displays advisory messages.
If a metal object or highly magnetic soil is so close to the searchcoil that the signal is
overloading the circuit, the message OVERLOAD - RAISE COIL will appear.
Such overloads will not harm the detector, but the detector will not detect metals properly
under these conditions. Raise the coil until the message disappears; the siren sound will
also stop. Resume normal detection.
The message RAISE COIL only appears when using the bc process, accessed through
PROCESS # menu selection. This message indicates the presence of a target which may be
too close to the searchcoil to be accurately identified. For better target identification, sweep
the searchcoil farther away from the surface of the ground.
The message PUMP COIL TO GB will appear when you push the trigger forward to
ground balance. See the Ground Balance section of this manual for instructions.
The message CAN’T GB can only appear when the trigger is pushed forward, invoking
FASTGRAB automatic ground balancing. This message appears when the detector is
unable to measure the soil in a manner suitable for ground balancing. This message is
usually the result of the presence of metal. Try another spot to find an area free of metal.
BACK LIGHT
The LCD is back-lighted for use in low light and dark conditions.
The backlight is always illuminated, but the illumination is usually not evident in daylight.
You cannot turn the backlight off. The single high-efficiency light emitting diode providing
the illumination is a low current device, and has a negligible impact on battery life.
