Maintaining
an
Optimal
Wireless
Connection
As wireless devices are increasingly more commonplace, the radio traffic in any given location
can change often abruptly. The myoMOTION system operates in the 2.4 GHz band which is
shared by wireless networks and personal communication devices. The myoMOTION system can
be set to operate at one of 8 different frequencies within the 2.4 GHz band as given in Appendix
B.
Routine examination of the local wireless environment is recommended in order to select the best
operating frequency for the myoMOTION system as in Appendix A. A utility program (inSSIDer)
that can be used to monitor WiFi activity is available for download at this link under Drivers and
Firmware:

The WiFi monitoring program must be installed on a PC that has WiFi capability. The utility
program uses the computer’s WiFi radio to detect and report on activity on the various WiFi
channels. The inSSIDer display will appear as follows.
Battery
Replacement
The Lithium Polymer battery used in the myoMOTION sensors and Data Logger is rated for a
minimum of 300 charge-discharge cycles. Typical usage is 500 charge-discharge cycles. As the
number of charge-discharge cycles increases the battery capacity slowly declines thereby
reducing run time despite being fully charged.
Brand new batteries can operate for more than 8 hours when fully charged. If the run time of the
Data Logger drops to 5-6 hours, battery replacement should be considered.
The myoMOTION battery packs should not be replaced by the user. Only qualified technical
personnel may perform maintenance.
