Operating Instructions
Prior to the signal search, be sure that all transceivers are turned
to search mode. Rotate the Tracker slowly in all directions (Figure
D) while moving along your signal search pattern. While searching,
be aware of other physical clues, such as equipment or extremities
protruding from the snow surface. When no signal is detected,
"SE" will flash in the distance indicator. Once a signal is detected
consistently, mark this spot and begin the coarse search.
Figure D
Slowly rotate the Tracker horizontally
and vertically in your hand, but move
rapidly during the signal search. Do
not abandon your search path until
you have captured a strong, steady
signal. Ignore irregular signals,
which can sometimes be caused by
electrical interference.
Coarse Search: The coarse search is the portion of the search from
where you have detected a steady signal to where you are close to
the victim.
Once the signal is consistently detected, rotate the Tracker slowly
{
on a horizontal plane until the center direction light is blinking.
The Tracker is now pointed in the direction of the strongest signal.
The four lights on either side of center tell you which way to rotate the
v
Tracker to engage the center light. The distance indicator tells you,
in approximate meters, how far you must travel (1 meter = 1.1 yards
or 3.3 feet). If the number on the distance indicator is increasing,
you are on the same axis as the victim's signal, but moving in the
opposite direction. Turn 180 degrees, engage the center search
light again, and continue your search in the direction the Tracker
is pointing. If you are stationary, but the distance is significantly
changing, you are probably detecting the signal of another rescuer.
Make sure all rescuers are in search mode before continuing.
You may find that, while following the directional lights, your route
follows an arc. This is because the Tracker2 follows the shape of
the electromagnetic signal coming from the transmitting beacon's
antenna. The distance displayed is the distance to be traveled along
that signal, not the straight-line distance from you to the victim.
Fine Search: The fine search is the final part of the beacon search,
which is performed on foot with the beacon positioned at or near the
snow surface. The objective of the fine search is to locate where the
