the signal field adjust-
ment knobs clockwise
increases the width of
the signal field. By
first tuning the coarse
signal field adjust-
ment and then using the fine tune signal field
adjustment, you can set the width of the signal field
to the desired distance. For example, on a one acre
property, the fine tune adjustment can be used to
move the signal field, which has been set by the
coarse adjustment, to protect a planter or exclude a
walk or driveway.
These adjustments do not alter the level of
correction from the receiver; they change the width
of the signal field sent out from the signal field
loop wire.
Checking the Signal Field
You can check the width of the
signal field by holding a Computer
Collar
®
parallel to the loop wire. Hold it at
the same height and angle that your pet
will be wearing the collar. Approach
the wire. The Computer Collar will
sound a warning when it
reaches the edge of the
signal field.
Note: A Computer Collar has
a fail safe mechanism. The
Computer Collar receiver will go
through three complete cycles of
10 seconds on and 10 seconds off
before it shuts down. It will not reactivate
until it is taken completely out of the the
signal field and then brought back into it.
A 12v battery connected to an ICT 725 will
power the signal field loop in the event of a power
outage. A 12v battery with a 5.0 Ah (amp hours)
rating will power the system for approximately 10
hours with the signal set at maximum. The greater
the amp hours (Ah) and/or the lower the signal
field is set, the longer the system will function
without AC power.
The green LED will turn red indicating that
AC power is lost and the system is operating in bat-
tery backup mode.

Note: The 12v lead acid battery
has a five year shelf life,
and should be replaced, whether engaged
often or not, after that time.
Important: The battery will take five times
its projected operating time to fully charge. A 5.0
The battery will take about 50 hours to charge to
full power. Charging of the external battery occurs
while the system is operating normally on AC elec-
tric power.
Note: NEVER leave the 12v battery
directly on the floor or ground.
This may lead to premature battery failure.
USE ONLY approved lead acid batteries.
Using non-lead acid batteries or batteries
with improper voltage can damage both the
transmitter and the battery.
Select a location for the battery near the trans-
mitter, but not on the floor or the ground. Put the
battery on a shelf or in a battery box.
Installing a Battery Box
1. Hold the battery box on the wall where you
are going to mount it. Use the box as a template and
mark the position of the 4 screw holes on the wall.
Drill 4 small pilot holes in the wall where the
screws will go.
2. Lace a 12” wire tie around the inside of the
battery box running the tie all the way around the
box to form a “U”.
3. Attach the wires to the battery.
One Red wire, the positive (+) lead, and one
Black wire, the negative (-) lead, are used to help
eliminate confusion.
