2.0 Obtaining W-Link information
The W-Link radio platform is compatible with the ARVA LINK
MUT ® devices. These can send each other information to increase data reliability.
Devices equipped with this technology are quicker in creating the victim/signal
list, and mark more reliably.
In EXPERT mode, a sign
the detected signal is carried by the W-Link frequency. You can thus be sure that
this detected signal is not interference, and that you can mark it reliably.
3.0 Marking/unmarking signals
As in NOVICE mode, a marked signal
In this mode, you can unmark the signal by moving the frame onto the marked
signal and again pressing the centre button
Marking/unmarking is only possible within a perimeter of about 3 metres. Beyond
that, the function is not available, to prevent accidental marking.
Analogue option
(available in both search modes)
To select/exit this option, simultaneously press the left- and right-hand
buttons for 1 second 2
To indicate Analogue mode, the symbol
screen.
In this search mode, the user controls his receiver's sensitivity. The more he
presses the right-hand arrow, the more sensitive it becomes, and vice versa.
An estimated number of detected victims appears in the top left.
The device gives sensitivity advice
of a victim is too high or low, the values displayed on screen will be wrong or
unreliable. The device displays small fl ashing arrows on the left and right of
the screen, so the user can optimise the sensitivity.
When these arrows disappear, the sensitivity is correct.
This mode has no direction feature. Assistance is by sound and number only.
When the device switches to analogue mode, it is at maximum sensitivity
(9 bars). You can increase sensitivity even further by pressing in the right-
hand arrow: the display disappears and the device is subject to only very low
interference, which can further increase its sensitivity. When you reduce
sensitivity again, the display reappears.
Analogue searching is complex and requires lots of training.
You must listen for the strongest signal, and use the numbers to guide you
closer. Proceed at right angles, keeping the device vertical. You can use the
earphone (optional) to better perceive sound-level differences.
