Each factory program can be modified to your own requirements, just enter the menu and
change the settings shown. Modifications are stored after the power is switched off (however
not when the battery pack is removed while the detector is turn on, which should never be
done). If the changes are not what you expected, then they can be reset using the factory
settings. Tables of all settings and space for noting your own are at the back of this manual.
The programs save all the setting except for the following: Backlight, Discrimination,
Sensitivity, Notch, Volume and Wireless. These six settings are saved by the detector after
turning the power off but are independent of the programs. The reason for separating these six
settings from the programs is so that they can be changed quickly, depending on the time of day
and search conditions. The user's current control over these settings is advisable and
necessary.
Turning the required program on is done by pressing the button in the detector’s
operating mode. The program selection screen will appear:
The buttons are used to select the program
you would like, then pull the trigger to enter the program. After
changing a program a ground balance needs to be done, and
the detector will guide you through this process.
If you want to reset a given program to the factory specifications, bring up the program
selection screen (by pressing the button) and use the button to go down to the
« Reset » option, then use the button to choose « Yes ». Use the trigger to leave the
program selection screen, the reset confirmation screen will then appear (« Really? »). Use the
button to select « Yes ». Use the trigger to complete, the chosen program will then be reset.
Resetting a program to the factory settings does not result in resetting user sound profiles.
NOTE: To allow an intuitive approach for users of our previous products, and those of other
manufacturers, Alter71 now has the option of choosing one of two types of identification scales.
One has 120 points of ID and is the scale from 1 to 120. The second has 180 points of ID and is
the scale from -90 to +90. Throughout this manual, information for the 180 scale is provided in
brackets as shown [180].
Alter71 is a detector which has a built-in metal object identification circuit. The detector
has 120 [180] identification points. It analyses the signal from a metal object several hundred
times per second, after each identification process, the internal memory of the device saves a
specific digital value. The values stored in the memory are used to calculate an average
identification value and an identification graph is shown. The average value depends on the
characteristics of the object that is below the search coil.
When the search coil is moved over an object made of a ferrous metal (e.g. steel) the
identification process will give a low value (e.g. 15 [-45]). Non-ferrous metals will give higher
identification values. The value for objects will depend on their size, thickness and the type of
material they are made of. Small, thin objects give values of around 40 [+10] and big, thick
ones, made from good conductors will show values above 100 [+80]. The soil will also have an
influence on the identification process. Rich mineral contents, and objects at great depth will
influence the values against those taken from above the ground.
