Module Integration into Host End Products
The QT-5000 Module Transmitter has been designed by Quantum5X Systems Inc. to be used exclusively
by Quantum5X as a building block for their wireless audio transmitter products. The module, as
designed, is a standalone unit that is ready for integration into final form factor with the limitation for
portable use as specified in RF Exposure compliance. For proper usage of the module, the module
integrator must ensure that the input power and input audio signal do not exceed the specified limits as
outlined in the specification section. Failure to do so will result in damage to the module.
QT-5000ModuleMounting
Mounting of the QT-5000 module must provide a solid, reliable, mechanical connection between the
module and the tap shoe. If the QT-5000 module is not securely fastened to the tap shoe, it may
become separated from the shoe during dancing and could cause harm to the wearer, the audience
member or the module. Below are two sets of instruction for mounting to two different styles of
shoes: high heel and a low heel style of shoe. In each case, it is important to maintain the minimum
10 mm antenna spacing of the module from the wearer.
High Heel Tap Shoe
The tap shoe first needs to be modified to allow the QT-5000 module to be fastened to the shoe.
Figure 3 -
Mounting Holes Drilled into
Four holes are drilled into the sole of the shoe, and up through the foot bed.

The T-nuts provide a threaded insert for the transmitter pod to screw into. The insole is pulled back
from the foot bed and the T-nuts are flush mounted into the foot bed from the top side of the shoe.
Figure 5 - Transmitter Pod attached to Shoe
The transmitter pod is held in place by four #4 bolts that are screwed into the T-nuts, which are
mounted into the sole of the shoe. It is very important to ensure the correct length of the screws used
so that the screw does not protrude above the foot bed of the shoe.
Low Heel Tap Shoe
In order to mount the transmitter module to the low heel tap shoe, the heel must first be modified. It is
recommended that the heel of the tap shoe be modified by a professional shoe maker to ensure the
modification is done in the correct manner.
Figure 6 - Heel Cavity
The heel of the tap shoe needs to be modified to allow for the transmitters module to slide into the
opening. The opening needs to be 58.4 mm X 36.75 mm X 15.3 mm.

Figure 7 - Module inserted into Heel
The opening needs to large enough to allow the transmitter to slide into the opening without
friction. If the opening is too tight pressure can be transferred onto the transmitter during dancing
and could damage the module.
Figure 8 – Transmitter mounting
The QT-5000 module is then securely mounted to the transmitter with two 1” long #4 screws.

Out-of-the-Box Setup
Ensure the QT-5000 is sufficiently charged by immediately inserting the charger.
Using the Reset Key after Charge
Earlier hardware revisions of the QT-5000 had an issue where the unit would occasionally need to be
reset after being connected to a charger.
It is recommended that each time the charger is disconnected from the QT-5000, the Reset Key (which is
attached to the cable of the charger) should be inserted into the charge port, held for 1 second, and
then removed.
After the Reset Key is removed, the Status LED will blink green 3 times.
Charge LED Colour
When connected to a charger, the colour of the Charge LED will indicate the progress of the charging
cycle. The LED is located on the front of the transmitter.
Note: After the LED changes from Amber to Green, it is recommended it be charged for 15
more minutes while the trickle charge completes.
GREEN
The battery
is charged and ready for use.
AMBER
The battery level
low, but can be used for short term use, such as setup or quick
audio tests.
