To search, remove Tracker from pouch, but keep harness and
lanyard attached to your body. If using without harness, keep
Tracker in a secure pocket, preferably in your pants or other garment
that won't be removed while traveling in the backcountry. Attach
lanyard clip to zipper or other solid fixture. If lanyard is removed from
harness or clothing for searching, keep attached to your wrist with
loop provided.

Power Supply

The Tracker2 operates with three AAA alkaline batteries. Use only
high-quality alkaline batteries of identical age and brand. Do not use
rechargeable, lithium, Oxyride, PowerPix or any other non-alkaline
battery. Replace with fresh batteries at the beginning of every
season.
In addition to being displayed at startup, the battery power level can
also be checked in transmit mode by pressing the options/SP button

door to help allow the unit to dry. To prevent corrosion of
contacts, remove batteries during extended periods of inactivity.
The manufacturer does not warranty damage caused by battery
corrosion.

The search process includes four phases: the signal search, the
coarse search, the fine search, and the probing/pinpointing phase.
Signal Search: The signal search refers to the process of
establishing a search pattern and looking for a signal. The search
pattern will be defined by the victim's last seen area, the size of the
slide, and the number of searchers. Refer to Figure C to establish
a signal search pattern. If the slide is less than 40 meters wide,
the signal search path will be directly up or down the center. If the
victim's last seen area is well defined, the signal search will follow a
direct path along the fall line (up or down) from this point.
If the slide is wider than 40 meters and there is no last seen point,
cover the entire slide area by using switchbacks in the search pattern
(Figure C). If multiple rescuers are available, establish a search
pattern where the space between searchers is no more than 40
meters and the distance to the edges is no more than 20 meters.
