When removing the transmitter from the charging cradle, the blue transmitter LED located inside the housing will flash for about 2 minutes to signal the proper operation of the transmitter . After about 2 minutes the transmitter LED is switched off. Thus, during a measurement, there is no LED indication of transmitter operation during a measurement, there is no LED indication of transmitter operation. This during a measurement, there is no LED indication of transmitter operation during a measurement, there is no LED indication of transmitter operation is to prevent the distraction of patients by simultaneous flashing of a relatively large number of transmitter LEDs. If during a measurement the remaining capacity of the built-in battery reaches a low value, the transmitter's LED will begin to flash again. In this state further operation of the transmitter is possible for a maximum of about 30 minutes before the transmitter will be switched off automatically. The flashing frequency will be noticeably higher and it is advisable to put the transmitter back into the charging cradle to reload its batteries. 4.2 Receiver 4.2 Receiver 4.2 4.2 Receiver Receiver Within the receiver's enclosure there is one blue LED for each transmitted channel. As soon as a wireless connection between a transmitter and the receiver has been established successfully, the respective receiver LED will start flashing. 4.3 Charging cradle 4.3 Charging cradle 4.3 4.3 Charging cradle Charging cradle Each charging slot of the charging cradle features a single indicator LED located beneath the slot. The indicator LED indicates three states:

Battery is re-charging:

In this state, the charging slot indicator LED will flash at a low frequency, indicating that re-

charging of the transmitter's build-in battery is in progress. Please note, that re-charging might take place from time to time even if the transmitter has not been used and stayed in its slot in the charging cradle. Battery has been re-charged:

When the LED is flashing, the data from the transmitter is received. Look at the software used with the system to check the signal. The software will show the signal in real time. Make sure the signal quality is good before you do the experiments. 5.6.2 Capturing and transmission of sensor signal With the steps described in Section 5.6.1 the wireless connection is established and the device is ready to start measuring. A mimimum sampling rate of 2.000 Hz is higly recommended for each analog output channel. 5.6.3 If you use transmitters with EMG electrode cable Connect a pair of electrodes to each electrode cable. The connectors on the cable will snap onto the electrode. The following single-use electrodes can be used with transmitters with EMG electrode cable: Ambu Blue Sensor N, REF: N-00-S / 25. Manufactured by Ambu A/S, Baltorpbakken 13, DK-2750 Ballerup, Denmark. www.ambu.com. Prepare the muscle area to be measured. Please see clinical guidelines for measuring surface EMG. Attach the electrodes to the muscle. Please use a clinical guideline to find the best place and on how to affix the transmitter securely to the body. Note that myon offers special fastening straps (P/N PA0003 ... PA0009) for this purpose. 5.7 Recommendations for optimal signal transmission and radio coverage 5.7 Recommendations for optimal signal transmission and radio coverage 5.7 5.7 Recommendations for optimal signal transmission and radio coverage Recommendations for optimal signal transmission and radio coverage Because of the nature of wireless transmission, radio signals sent by the transmitter are not guaranteed to reach the receiver. The maximum legal limit on the transmission power means that the maximum theoretical transmission distance is up to 200 metres. In practice, indoor environ-

ments tend to limit the distance to 20-30 metres. Walls, floors and furniture limit the transmission range depending on what type of material they contain. Concrete walls, for example, are not easily penetrated, and such walls will limit the range.

Please read the next sections carefully and follow the recommendations to achieve optimum range of the system. 5.7.1 Receiver An elevated position may be advantageous. The receiver should be positioned with a free line of sight to the measurement area. As far as possible, try to position the receiver centrally in the measurement volume. As far as possible, avoid using other signal emitting devices such as wireless phones and microwave ovens in the measurement volume. Depending on the room's geometry, small changes in the receiver's position may have a large impact on the transmission range; if the range is insufficient, try to reposition the receiver. 5.7.2 Transmitter Optimum placement of the transmitter improves the range; the transmitter is designed so that the signal is focussed towards its top hemisphere. As a rule of thumb, the transmitters should be positioned as much lateral on the body as possible and ideally within a line of sight with the receiver.

. 1 N O S R E V I Image 11: Proper EMG signal recording 9.3.2 Visualization of transmission errors The visualization of transmission errors is done in two different ways:

If the wireless connection between a transmitter and the receiver is broken only shortly for less than one second, the receiver will output a zero amplitude signal on the affected channel. In most cases only one or two frames of transmission may be lost, resulting in a signal drop to zero for 5 or 10 ms. The example in Image 12 below shows a longer drop in transmission for about 150 ms. Image 12: Visualization of short transmission errors If the wireless connection between a transmitter and the receiver is broken for more than one second (e.g. because of a transmitter switching itself off due to battery drainage or because the distance between the transmitting module and receiving unit is exceeded), the receiving unit will output a sine signal with maximum output amplitude (+/- 2,5 Volts) on the affected channel.
