Setting the Signal Field Width
The signal field width is what activates the R21 v4.0 Titanium Computer Collar
®
. The
signal field can be set to various distances from the signal field wire. The distance from
the wire loop to the edge of the signal field is called the signal field width.
There is one signal field adjustment knob on ICT 801 and ICT 810 transmitters and two
signal field adjustment knobs on the ICT 802 transmitter. See page 5, 6, or 7 as
appropriate for location of signal field adjustment knobs. Turning the signal field
adjustment knob clockwise increases the signal field width. Conversely, turning it
counter-clockwise decreases the signal field width.
IMPORTANT: These adjustments do not change the correction level of

field wire. Hold the collar so the receiver
is about the same height and at the same

it. Walk slowly toward the signal field wire.
The receiver will activate when it is at the
edge of the signal field.

receivers have a fail-safe mechanism. Should the pet become caught in the signal
field, the receiver will go through three cycles of 10 seconds ON, 10 seconds
OFF, and then shut down. The collar will not reactivate until it is completely
removed from the signal field, and then brought back into it.
