field-replaceable antenna mounted on the transmitter. The antenna
simply screws into the transmitter's antenna fitting. Check the installed
antenna occasionally to make certain it is snugly attached (only finger-
tight). If the received signal is marginal, experiment with different
transmitter positions on your body or instrument or try repositioning the
receiver. Do not attempt to modify the transmitting antenna. Replace
it only with the same parts, available from the Audio-Technica Service
Department.
