Do not rely solely on the readings from the Hand Held Receiver to locate
the activated transmitter
.
The LCD Display indicates the ID number of the activated transmitter and
the Number Display indicates the relative strength of the signal with numbers
from 1 to 99. A higher number indicates the stronger signal and, therefore,
the approximate direction of the signal from the transmitter. Pointing the
Hand Held Receiver in the direction of the strongest relative signal and moving
in that direction should lead to the activated transmitter.
Use the signal strength numbers below 50 to establish a general direction to
proceed. Practice is required to interpret these low signal strength numbers
because they may arrive at the receiver from many different directions. Look
for
broad
increases in signal strength; for example, look for an increase from
20 to 30 as significant. Do not try to interpret small changes, such as the dif
-
ference between readings of 20 and 21. Larger increases are a more reliable
indicator of the direction to the strongest signal.
When the signal strength number is 51 or higher, the PAK-TRACKER Receiver
will produce a
variable pitch tone
once per second that corresponds to the
signal strength: A stronger signal will produce a
higher
pitch tone and a weaker
signal will produce a
lower
pitch tone.
The higher numbers indicate a stronger signal, but still require practice to
interpret. Try to identify a path where the variable pitch tone is
both
active con-
sistently and continues to get higher in pitch. Again, look for
broad
increases
in signal strength to be significant.
Use a
Read-Interpret-Follow
process while watching the digital display
for the highest number and listening for the highest pitch of the tone as an
indication of the strongest radio signal.
Always update training with each new piece of equipment. Even if users have
trained with PAK-TRACKER Hand Held Receiver before, new equipment may
have different operating characteristics that users must become familiar with
before entering an emergency or hazardous situation.
WARNING
ALWAYS UPDATE TRAINING WITH EACH NEW
PIECE OF EQUIPMENT. EVEN IF YOU HAVE USED
THE SCOTT PAK-TRACKER LOCATOR SYSTEM,
NEW EQUIPMENT MAY HAVE DIFFERENT OPER-
ATING CHARACTERISTICS. USE OF THIS DEVICE
WITHOUT PROPER TRAINING AND UNDERSTAND-
ING OF ITS OPERATION MAY CAUSE ERRORS IN
JUDGMENT BASED ON MISINTERPRETATION OF
LOCATOR INFORMATION, WHICH MAY RESULT IN
SERIOUS INJURY OR DEATH.
