Declaration of compliance
Manufacturers Name: Oz Inventions
Manufacturer’s address: PO Box 86, Warrnambool, Victoria. 3280
Declares that the product
Product name: Xpression fX Black Magic Motion (Sensor)

Hook and loop attachments
Quick start manual
Safety and care of sensor-transmitter
When removing or inserting the internal battery, care should be taken to avoid touching internal
components. The Battery must go UNDER the double hooks, NOT on top of the hooks.
A screwdriver is required to remove the cover of the sensor for battery insertion/removal, and also
for removing the battery. Care should be taken with the tools used to remove the base and remove
the battery from its holder.
Proper battery disposal is required. When the battery becomes discharged, dispose of with regards
to the best welfare of the environment. Usually this will mean disposing at a recycle depot.
Dismantling the device further than removing the cover for battery insertion/removal, may damage
the device. Other than the battery, there are no user serviceable parts inside the device.
Only use battery type CR2032. Using other battery types could damage the device and/or present a
safety hazard.
If the device will not be used for long periods of time (months), remove the battery
The device transmits radio frequency energy. The power transmitted is low and presents no safety
hazard. However, precautionary measures require that the device is not worn on the human head.
The device is a low power RF transmitter but transmits on similar wavelengths to WIFI routers, blue
tooth devices and microwave ovens. Should interference be experienced, position the device further
away from the device that is interfering or being interfered with. Interference can also be limited by
operating the device on different radio frequency channels.
Should the device malfunction, a restart or battery removal may resolve the problem. Otherwise the
manufacturer should be contacted. There are no user serviceable parts inside the device.
Avoid contact with, and environments, known to cause adverse effects with electronics and small
moving parts, such as liquids, dust, sand, high humidity, high temperature and vibrations.
The provided adhesive hook and loop tape is to be adhered to whatever the sensor-transmitter is to
be attached to. Consideration should be given to the care of the item receiving the hook section as
the chemical makeup of the securing substance may damage some surfaces. Consideration should
also be given to the circumstance of removal of the hook section as the adhesive may damage the
item it is adhered to, when it is removed.
The bond of the hook and loop sections after being placed together, is secure for general movement,
but avoid aggressive shaking else the sensor may come loose and experience fall damage.

Introduction
Xpression fX Motion sensor-transmitter from Oz Inventions, is a motion sensing wireless radio frequency
transmitter. It is designed for use with Xpression fX devices such as Black Magic Motion modulator/receiver.
The sensor-transmitter sends motion data based on tilt, rotation, speed and force to the modulator/receiver.
It is designed to be attached to various body parts, musical instruments and any other moving object with
the necessary motion to create the needed motion data.
The device provides unique expression capability. Many of the features have not been available previous to
the release of Magic Motion and so it is advisable to read through this user guide.
The sensor provides the following features-
Maximum clear view transmission range is 30 meters ( 5 - 10 meters in realistic conditions)
Three operating channels for simultaneous use of multiple devices and/or avoiding interference
10 hours continuous battery use
Battery save mode (auto shut-off)
Easy attachment via hook and loop accessories
Controls
Figure 1 –Controls
Channel and power indictor –Indicates the channel via color and power via illumination
On / Off / Battery save mode / Channel select –press to turn on; press to turn off; Long press from
boot to change channel; medium length press from operation mode to change battery save mode
Strap eyelets –Eyelets for securing strap

Inserting the battery
1. Remove the two screws securing the base to the shell and lift the base off
2. Gently slide the battery UNDER the double hooks, positive side (+) visible, and press the battery into
place
3. Fit the base and screw it into place
Figure 2 - Inserting the battery

Removing the battery
1. Remove the two screws securing the base to the shell and lift the base off.
2. Gently slide a small screwdriver under the battery OPPOSITE from the double hooks, and gently lever
upwards. Remove the lifted battery with your fingers.

Turning on and off
Figure 4 –Turning on and off
Power ON
1. Hold the on/off selector until the indicator illuminates (2 seconds)
2. Release the selector. The sensor is now transmitting
Power OFF
1. Hold the on/off selector until the indicator extinguishes (2 seconds). The sensor is now off
Note that the device will pass through battery save mode as it powers down. This is indicated by a change in
indicator brightness. See ‘Changing battery save mode’ pg 9
*The indicator will become dimmer as the battery is discharged. At a very low point of charge it is possible
that the blue indicator will extinguish before the device ceases operation.
Changing channels
The sensor-transmitter will transmit on one of three selected channels. The channels are within the 2.4GHz
spectrum and are indicated by the channel indicator as red, green or blue.
Figure 5 –Changing transmission channels
1. Press and hold the channel selection button from the power off mode, until the channel indicator
illuminates.
2. Continue to hold the button. After 2 seconds channel selection will begin to cycle as indicated by the
changing color of the light.
3. Release the button at your chosen channel

Changing battery save mode
The sensor-transmitters default state from manufacture is to stay permanently on when switched on.
However, the sensor-transmitter can be placed in to battery save mode, where it will automatically power
down after 5 minutes of non-motion.
Figure 6 –Battery save mode
Battery save mode ON
3. Hold the on/off selector until the indicator dims (1 second)
4. Release the selector. The sensor is now in battery save mode
Battery save mode OFF
2. Hold the on/off selector until the indicator brightens (1 seconds).
3. Release the selector. The sensor is now in permanent on mode

Attaching the sensor-transmitter
The sensor-transmitter comes supplied with hook and loop attachments.
Self-adhesive hook and loop sections
1. Attach the 3.5cm loop section to the base of the sensor-transmitter by removing the backing and
pressing the adhesive side on to the base.
Figure 7 –Stick the loop section on to the base
*The loop section is preferred on the base, as it is smooth and therefore less irritating to the skin than
the hook section. Also the loop section will not interfere with the hook section of the strap if it is
fitted.
2. The hook section is to be adhered to whatever the sensor-transmitter is to be attached to.
*Consideration should be given to the care of the item receiving the hook section as the chemical
makeup of the securing substance may damage some surfaces. Consideration should also be given to
the circumstance of removal of the hook section as the adhesive may damage the item it is adhered
to, when it is removed.
3. After securing the adhesive hook and loop sections, place the two surfaces together.
Figure 8 –A possible place for attachment
The hook & loop bond is secure for general movement, but avoid aggressive shaking else the sensor may
come loose and experience fall damage.

Hook and loop straps
The hook and loop straps are to be fed through the eyelets of the sensor-transmitter and secured to an
object.
1. Feed the label through eyelet with the lettering exposed, as shown in the picture below
2. Feed the label through the eyelet on other side and pull it all the way through until the buckle is
pulled up against the eyelet
3. Feed the label end through the buckle
4. Pull the hook side over and attach to the loop material
