on interpreting the signal. As you proceed with more complicat-
ed searches, it is important to keep moving as you are process-
ing new data at each new location rather than re-sampling the
same data when stationary.
Follow a similar procedure as in the previous example. Have
someone from your family or unit hide the transmitter in an area
that will provide a range of obstructions (physical and/or man-
made) and special situations (inside a building, adjacent to metal
equipment, etc,) to the location team. Unfold the antennas, acti-
vate the receiver, select the correct channel and determine if a
signal is present. If the signal is heard, slowly sweep 360
degrees to ascertain the direction of strongest signal. You may
notice that you receive a relatively similar strength signal from
two or more directions. Under these circumstances, first try to
ascertain whether a metal building, hillside or other obstruction
is the source of the "bounce" signal. While there is no universal
method for analyzing multiple strong signals, try the following
when encountering a "bounce signal candidate:"
• Move to another location some distance away and repeat the
procedure. Try to remember the bearing that you received
strong signals at the first location and note if a new signal
comes from a common point.
• If you can easily reach a higher elevation (increasing the odds
for a line-of-sight signal), take another reading.
• If the object at the source of the bounce is small, try moving
perpendicular to a line between you and the source of the
signal. Often if the angle is changed the strength of the signal
will change significantly. If this occurs, review the initial angle
to create a possible candidate bearing to the transmitter or
eliminate this bearing (bounce signal).

NOTE:
As you search with the receiver on, you may note that after
15 minutes of continuous use where no key is pressed, the receiver
automatically turns off (you may need to turn the receiver on again).
