Using the Countryman E6i is easy. First, connect it to your Shure transmitter via the Switchcraft TA4 - Female connector. Adjust the flexible boom to position the mic close to your mouth for the best sound. Put on the ear - piece and adjust the silicone ear - pads for a comfortable fit. When using outdoors, attach the windscreen to reduce wind noise. As for maintenance, you can easily remove and replace the cable if it gets damaged. Store the mic in a dry place and avoid exposing it to extreme temperatures. Make sure to follow the power requirements specified in the manual to keep it working properly.
