VALUE 10F
, indication of small ferromagnetic objects is identical to the
previous mode. However the sector of nonferrous metals is broken into 9
separate sectors with a division of 10 units ( VDI). The higher the VDI the higher
the tone generated. The variability of the frequency of the tones is set under the
parameter
Frequency of Sound.
VALUE
91F
, indication will be similar to the mode
10F
, accept that instead of the
tones being divided into 9 sectors they will be set to 90 sectors . Meaning each
positive VDI number will have a corresponding tone. The variability of the frequency
of these tones is set under parameter
Frequency of Sound
.
Deciding which number of tones parameter to use depends on the users
goals. On a site where the collection of all metal targets is desired then a setting
of
1F
would be fine. However if one has good hearing and wants to be able to ID
targets by audio response mainly then a setting of
91F
would give the user the
greatest amount of target information via audio only.
SOUND FREQUENCY[1-10]
Defines the range or variability of frequency for tone
selections of 10F and 91F. In any other number of tones selection this parameter
has no affect. With a value of 1 all non ferrous targets would give a high tone with
no variability. While a setting of 10 would give the greatest variability of
frequencies amongst the tones.
LENGTH FE [SHORT/NORMS]
Defines the length of the FE tone.
NORM
– under
this setting the duration is the same as for non ferrous targets whereby the
duration is based upon size, shape and strength.
SHORT
– Under this setting
all ferrous targets give a very short audio response regardless of size, shape
etc.
OVERLOAD VOLUME [0-10]
Sets the volume level of the target overload warning.
Large objects at shallow depths can overload the device and will cause strong
distortions and erroneous information. When the parameter is set above 0 there will
be an audible melody whose volume is relative to the parameters setting. Also there
will be a corresponding warning message displayed on the LCD display.
THRESHOLD VOLUME[0-5]
Sets the volume level for the background threshold.
SMALL SIGNAL VOLUME [off/1... 6]
Adjusts the volume of deep or weak
targets. When set to off the response of weak targets is minimal. As this level is
increased the volume of weak targets is amplified. At a setting of 6 all targets will
have the same audio level response regardless of whether they are weak or
strong.
NOTE: Any of the parameters mentioned under the Audio menu have
separate profiles for the external speaker and headphones. Such that any volume
level adjustment performed while wearing headphones will be saved to the
headphone profile while any adjustments made while using the external speaker will
be automatically saved under that profile.
