Another way to change the discrimination pattern is to search as normal and when an unwanted target is encountered, press the "Set Disc" Touchpad and that segment will no longer be illuminated.
A special note about detector operational settings. Any changes that have been made will be retained when the detector is turned off. These changes will remain until changed by the operator or until the detector is returned to the factory default settings by pressing and holding the POWER Touchpad.
When the Depth Touchpad is depressed, the display will show a row of segments on the upper LCD bar. This is indicating the Depth/Sensitivity setting of the detector. Approximately 75% is the factory default setting. Hunting in some locations there may an abnormal amount of static or interference, in these instances it may be necessary to reduce the depth setting until the audio sounds become stable once again. This is also the action to take when searching with a companion and when near each other the detectors exhibit erratic and unstable operation. When searching for very small or very deep items it might be beneficial to increase the depth setting as much as possible, up to the point that the detector becomes unstable.
Depressing the Audio Touchpad will graphically indicate the audio level established. Changes to this level can easily be made by pressing the + or - touchpads until the desired threshold level is attained.
BATTERIES:
GTA Series detectors require eight (8) AA batteries. They are contained in two battery holders of four each. These holders slide into the Battery Pack beneath the Arm Cuff assembly. When replacing batteries observe that the polarity of the batteries is correct in the holders and that the holders are inserted in to the case with the rivet at the bottom of the holder towards the center of the case. Failure to install the batteries correctly will result in electronic damage to the detector which will require time lost from hunting and an avoidable expense.
The detector is supplied with Alkaline batteries for long life, but rechargeable batteries may be used if desired. There is no provision for
When storing the detector for extended periods the batteries should be removed from the detector and from the holders.
Note: When
Battery Test:
Each time the detector is turned on the batteries are automatically and audibly checked. Three or four bars on the battery scale indicate the batteries are very good, two bars and the batteries are adequate. One single bar and it is time to replace the batteries.
