WARNING
CONTINUED TRAINING AND PRACTICE IN A
VARIETY OF SITUATIONS IS ESSENTIAL TO
DEVELOPING THE SKILLS TO PROPERLY IN-
TERPRET THE INFORMATION PROVIDED BY THE
PAK-TRACKER LOCATOR SYSTEM. USE OF THIS
EQUIPMENT WITHOUT TRAINING AND PRACTICE
MAY JEOPARDIZE ALL PERSONNEL INVOLVED,
WHICH COULD LEAD TO SERIOUS INJURY OR
DEATH.
BEGIN THE SEARCH
To begin searching, hold the Hand Held Receiver horizontally at waist height
in front of you. The row of LED’s and the Number Display on the Hand Held
Receiver indicate the relative strength and, therefore, the approximate direction
of the signal from the transmitter. The Number Display shows numbers from 0
to 99, where the higher number indicates the stronger signal being received.
Pointing the Hand Held Receiver in the direction of the strongest relative signal
and moving in that direction should lead to the activated transmitter. When the
signal strength rises above the number 50 level, the row of LED’s will begin to
light starting with red at the bottom, yellow in the middle, and green at the top.
The PAK-TRACKER Hand Held Receiver averages four readings per second.
Use a Read-Interpret-Follow process while watching the digital display for the
highest number as an indication of the strongest radio signal. If there are features
such as doors, hallways, openings, or windows, take readings at each feature
to determine a possible general direction for the signal. If you use a sweeping
motion, sweep very slowly in a horizontal direction first. Sweep vertically if
you suspect that the signal may be coming from a higher or lower floor in the
building. Always pause for a reading. Sweeping too fast may average a high
reading with a low reading, resulting in misleading information.
Always move toward the highest relative signal strength displayed. In general,
the closer you get to the transmitter, the higher the relative signal strength.
Multiple signal paths are possible. See FIGURE 2. The relative signal strength
must be interpreted with all other available information. The transmitter signal
will pass through some materials, reflect off some materials, and be absorbed
by others.
