displayed. If this condition exists, move the pickup coil to another part of the Monitor case. This
procedure should be repeated until the message
“no video sync available”
ceases to occur. The
video synchronization mode may be exited at any time by selecting another type of
synchronization mode using the ‘y’ command.

7.17 Long Ranger Transmitter
The Long Ranger Transmitter is an optional device which produces a larger electro-magnetic
field and therefore enables greater range capabilities. The 18” acrylic sphere is attached to a
pedestal, which is typically mounted on the optional tripod assembly, or suspended from the
ceiling. The advantage (besides longer range, when using the Long Ranger Transmitter in lieu of
the standard transmitter) is a better signal-to-noise ratio (less noise) so that whole body tracking
can easily be done.
7.18 4” Transmitter
The 4” Transmitter is an optional device which allows up to 40% more range than the standard
2” Transmitter. The 4” Transmitter can be employed in virtually the same environments as the
standard transmitter, and even uses the same mounting hole pattern–allowing increased range
without degradation in the data.
7.19 Short Ranger Transmitter
The Short Ranger Transmitter (TX1) is an optional device, which produces a smaller electro-
magnetic field for precision work in a restricted space. It is dimensionally the same as the
receiver and is shown in
. There are two advantages when using the Short
Ranger Transmitter in lieu of the standard transmitter: a small volume means 1) less
susceptibility to field distortions with metals nearby; and 2) no concern about transmitter
aperture when closely approaching the device. The Short Ranger requires a factory modification
to the SEU which needs to be addressed when the product is ordered; other transmitters can no
longer be operated by the modified SEU.
7.20 Mini Receiver
The Mini Receiver is an optional device, 10-12 mm in size, whose position and orientation is
measured relative to the transmitter, like all receivers. Because of its small size, its maximum
range from the transmitter is reduced to 35-40% that of a standard receiver. Refer to
