7.1 Manual Volume Control in Analog Mode
(Analog Mode = Manual)
In the analog mode (with activated manual volume
control), the receiver sensitivity (volume) can be set
manually. This makes acoustic searches possible,
as conducted with traditional transceivers. This
mode is i.e. used when applying „finesearch in a
circle”, in surroundings with strong interference
such as high voltage power lines or in very complex
burrial situations.
Buried subjects are located based on the acoustic
change in intensity of the received signal. The use
of this mode requires intensive training.
In order to be able to use the manual volume con-
trol in analog mode, you must enable it in the «Set-
tings» by choosing «Manual» in the setting «Analog
mode».
When using the manual volume control in
analog mode, the display can be disabled, in
order to significantly increase the range. By
pressing the
- key for + on volume level 8, the
display is deactivated; subsequently pressing
the
- key for – activates the display again.
See
chapter «Extended Search Strip Width in Analog
Mode»
By activating the manual volume control in ana-
log mode, an analog tone is used for the group
check, as well.
Once your Barryvox is configured accordingly, you
can toggle between standard and analog mode with
manual volume control by briefly pressing and hold-
ing both keys at the same time for three seconds.
The sensitivity of the receiver is initially controlled
automatically.
The user can manually change the sensitivity by
pressing the
- key for + and the
- key for –.
A1 represents the shortest, A8 the greatest distance
to the buried subject.
Check as well the visualization of these procedures
in the «Cockpit Search in Advanced Profile».
As soon as the volume is set manually, a border is
displayed around the volume bar. The automatic
volume control is disabled. If the volume is set too
high or too low, the distance and direction indica-
tions become unreliable, and a blinking display
prompts the user to adjust the volume.
To return to the standard mode, both keys must be
pressed simultaneously.
Orthogonal Search System
(Coarse and Fine Search)
Orthogonal search system with manual selection of
the receiver sensitivity:
1.
Maximum tone
Search for the loudest tone on a straight line.
2.
Reduce volume
Reduce volume until the tone is barely audible.
3.
Turn 90°
Search at a 90° angle to the previous direction.
Remember
•
Hold the transceiver vertically.
•
Search quickly.
The volume only changes
if you are moving.
•
Search quietly.
This way you can detect
differences in volume easier.
5.2 Settings
The default settings of the device are configured
optimally for normal use. Advanced and profession-
al users have the possibility to activate additional
functions and customize the Barryvox to their needs
Most customizable features make the Barryvox
a sophisticated device. You should only change
the default settings if you have a specific reason
to do so.
To access the «Settings», switch the transceiver
from OFF to SEND and press any key. The confirma-
tion «activated» appears at the bottom of the
Display in analog mode
(on the second lowest
volume setting)
