Field Marshall Tracking Receiver
In the Field
When you're ready to use the system in the field, tune in the
signal just before letting your bird or dog go. That ensures you'll
be ready with the best signal instead of having to try to locate it
in the rush of the moment when the animal first becomes lost.
A few pointers on tuning:
•
Set the numbers to match the frequency shown on the
transmitter. From there you might rotate the third num-
ber up or down to get the best signal.
•
Tune the receiver for the loudest sound after the trans-
mitter is on the animal and has reached the outside air
temperature. This is not necessary with Marshall trans-
mitters but other brands can experience frequency drift
with changes in temperature.
•
If you tune in while the transmitter is sitting next to you
on the car seat, the signal will be so powerful that your
receiver may pick it up on adjacent or incorrect
channels. If you mistakenly tune in on the wrong chan-
nel the signal may sound fine in the car, but will be
quickly lost when the transmitter is far away. To avoid
this, set the Range Switch on Near while tuning any-
where near the transmitter.
Try locating your animal several times for practice. Experiment
with holding the receiver antenna vertically and horizontally
while watching the position of your animal. Use the system
many times until you feel confident in finding your animal with
telemetry. When your bird or dog is lost is not the time to be
learning how to use telemetry.
