These broadcast frequencies may be used exclusively in Canada, theU.S., Mexico, all Central and South American countries, and Australia.• Do not use the MX692 microphone on metal surfaces.• Do not place laptop computers, open or closed, in front of the microphone during use.• When using multiple wireless systems, use a single group and successive channels.This will avoid interference between systems.• The MX692 wireless microphone/transmitter uses the Shure UC4 wireless receiver.
English – 10POSITIONING THE MICROPHONEWith the standard cardioid cartridge installed, theMX692 will pick up audio at conversational volume levelswithin 1.5 M (5 ft.) in a 130 degree radius.As a general rule for tables with multiple seats, a singlemicrophone should be used for every two people speaking.< 1.5M (5 FT.)130°
English – 11POSITIONING MULTIPLE MICROPHONESIn any installation, good vocal amplification can beachieved by following the positioning rules on page10.For information on receiver setup and positioning,see your UC4 Wireless System user guide.
English – 12POSITIONING YOUR RECEIVERThe receiver may be wall-mounted or used in conjunction with a remote antenna system, such asthe Shure UA500. The distance between transmitter and antenna should never be greater than 15meters (50 feet) or less than 3 meters (10 feet). See your UC4 user manual for additional informationon receiver and system setup.72>3 M (10 ft.)<15 M (50 ft.)UC4MX692
