Cautions During Operation 1. When this in-ear wireless monitoring system is used together with a wireless microphone system, make sure they are not on close frequencies to avoid their possible interference with each other. 2. If using a coaxial cable to connect the transmitter to a remote antenna, note that the coaxial cable must be 50 and less than 5 meters long for optimum operating range. 3. Maintain line-of sight-operation at all times, when possible, for best performance and range. 4. For best performance use only the supplied power adapter for the transmitter. 5. If using earphone other than those supplied, make sure they have a sensitivity of at least 110dB/mW. Note that the receiver's battery life diminishes as earphone volume is increased or earphones have low sensitivity, which requires more power to drive to a desired volume. 6. Always remove batteries from receiver if not using them for a long time as leaking batteries can damage the unit. 13 Specifications Operating Frequency Range Modulation Audio Frequency Response T. H.
