ing an area that is not supposed to be covered.
When the signal field is covering the area that
you want it to, permanently fasten the IFA 12 in place.
Note: When the signal field is set where
you want it, you can use a tiny dot of
nail polish or paint on the signal field
adjustment knob and the case of the IFA 12
to mark the setting for future reference.
Mounting the IFA 12 Transmitter
To permanently fasten an IFA 12 in place, drill
two pilot holes aligned vertically and centered 2 1/2
inches(6.35cm) apart. Turn a 3/4 inch,
#10
(4.8x19mm) pan-head sheet metal screw into each
pilot hole until about 1/16 of an inch(1.6mm) of space
remains between the surface the transmitter will be
located on and the underside of the screw’s head.
Center the round end of the keyholes on the bottom of
the transmitter’s case over the screws so that the bot-
tom of the transmitter is flush against the mounting
surface. Slide the transmitter down to lock the heads of
the screws in the keyholes.
Warning: The A12 Computer Collar is
designed for indoor use exclusively,
using an A12 outdoors will void the
manufacturer’s warranty in full.
Note: An A12 Computer Collar receiver
will not work with any outdoor Invisible
Fence transmitter, or any indoor transmitter
except an IFA 12.
Note: The A12 Computer Collar
receiver is factory set to 7K, it will not
work with an IFA 12 when the transmitter’s
operating frequency is set to 10K.
Note: If you want to use both an indoor
IFA 12 system and an outdoor Invisible
Fence
®
system, you can use the same R series
Computer Collar for both systems. The IFA 12
transmitter(s) must be set to the same operating
frequency that the outdoor system’s transmitter
is set to, either 7K or 10K.
CAUTION AND CARE
An Inv i s i ble Fence Computer Collar
will not wo rk unless:
1. You train your pet as pre s c ribed in the
I nv i s i ble Fence Safe Dog
®
training protocol.
2 . The Computer Collar receiver is wo rn snu g ly on
your pet’s neck under the lower jaw.
3. The Computer Collar is adjusted so that the
receiver’s posts are touching your pet’s skin.
4. The Power Cap
®
b at t e ry in the C o m p u t e r
C o l l a r re c e iver is good and is corre c t ly installed, see
“Changing the Computer Collar Receiver’s Power
Cap Battery”, on page 7.
5. The IFA 12 is on and producing a signal
fi e l d.
The following precautions should also be taken:
1. A lways take the Computer Collar off
your pet befo re you make any adjustment
to your Inv i s i ble Fence system.
2. Gra d u a l ly allow your pet to become accus-
tomed to its new Computer Collar. Ta ke off the
collar eve ry night during the fi rst month and peri-
o d i c a l ly there a f t e r. This will ensure proper fit and
avoid the possibility of any irritation that the posts
may cause to your pet’s skin.
3. Check the Computer Collar near your tele-
v ision set(s). Although the re c e iver has a decod-
ing circ u i t , some televisions may produce a coded
signal similar to the Inv i s i ble Fence signal and
m ay cause the re c e iver to activate when it is cl o s e
to a telev i s i o n .
4. DO NOT s e c u re the corre c t i o n
posts in the re c e iver with any kind
of glue or adhesive.
A LWAY S use the post
tightening tool to tighten
the re c e iver posts.
