For syncing Receiver-Selected Frequency to Transmitter: Press the receiver Auto-Scan Button (29) to locate an open frequency/channel. Point the Receiver Infrared IR receptor/Sensor(22) at the transmitter Infrared Transmission Window (5) and press the SYNC Button (28) on the receiver until the transmitter's LCD Screen (4) displays the same frequency as the receiver's LCD Screen (21). 8. The receiver's LCD display can be locked with the LOCK Button (27) to prevent accidental adjustment, or to unlock it to make an adjustment later. The "LOCK" icon will be displayed on the LCD screen in lock mode only. Push the Lock button to unlock. 9. The headphone audio can muted temporarily by pressing the MUTE Button (30). Press again to un-mute. The "MUTE" icon will be displayed on the LCD screen in mute mode only. 10. Wearing the Bodypack Receiver. The Belt Clip (31) rotates 180˚ for attaching to belt with receiver's top panel in either up or down position as pictured below. 11 Multiple System Operation Selecting a Channel/ Multiple System Operation Both the PEM-1000T transmitter and PEM-1000R receiver offer a choice of 100 channels in the UHF band. Select an open frequency, that doesn't interfere with any other PEM-1000 or UHF wireless Mic system you are also using, by pushing the SET Up Button (7) and Manual Up (6) or Manual Down (8) buttons on the front panel of the PEM-1000T until the channel you want is displayed on the LCD Display (4). You will also need to select the same channel for the transmitter (see Transmitter Operation instructions above). If different mixes are required for the different performers, additional PEM-1000T transmitters and receivers set to other channels must also be used, and each transmitter must be fed a different mix from the console as desired. Depending on the band(s) you are using and open channel availability within the band(s), up to 8 PEM-1000 systems on different frequencies can be operated simultaneously to provide multiple discrete mixes to the performers. [Note: After selecting a frequency on the transmitter, you must also check with the receiver to ensure that the chosen channel is open (i.e., no other transmissions from other sources, such as UHF TV channels in your area, operating at the same frequency). Turn off the PEM-1000T transmitter, and monitor the signal from the PEM1000R (see PEM-1000R instructions page). It should be silent. For optimum operation and range, if you receive any transmissions or static you must choose another channel that is clear.] [Note: If, after you complete the set-up, you experience interference or unsatisfactory audio performance, change the channel until the problem goes away. In the extremely rare circumstance that such a problem persists, turn off all UHF wireless Mic being used or move their receivers physically away from the PEM-1000T transmitter. In some instances, UHF wireless Mic and the PEM-1000 system can interact if they are too close in frequency. Contact the NADY SYSTEMS Service Department for further information if necessary (see SERVICE)] Multiple Monitor Mixes Any number of PEM-1000R receivers can be used with a single PEM-1000T transmitter set to the same channel. Although there are individual controls on each receiver allowing different levels of volume, each receiver will receive the same transmitted monitor mix (see Selecting Stereo or Mono Mode Reception above for exceptions). If different mixes are required for the different performers, additional PEM-1000T transmitters and receivers set to other channels must also be used, and each transmitter must be fed a different mix from the console as desired. (Note: Never set more than ONE transmitter to the same operating frequency.) Testing Receiver Range Wearing your receiver and earphones, walk around the stage area and listen for audio quality. Depending on room size, obstructions, amount of reflective metal surfaces, and other conditions that may affect RF transmission, it is normal that the audio may disappear or "drop out" in certain locations. Such zones, otherwise known as "null spots" are very small and fixed in location if you are within 100 feet of the transmitter and will become larger as you approach the ultimate range of your system in that location (up to 500 feet, Depending on site conditions). Generally, it is possible to eliminate such "null spots" by moving your PEM-1000T transmitter as little as 12-18 inches in any direction. If that is not convenient (e.g., because the PEM-1000T is rackmounted), you can also use an optional remote antenna. Contact the NADY SYSTEMS Service Department for information about remote antennas for the PEM-1000T. After you move the transmitter or relocate a remote antenna, range walk the stage and other areas you will use in your performance to again check for consistent reception. You are now ready to use the PEM-1000 system for wireless personal in-ear monitoring. (Note: Due to the strong transmission power of the PEM-1000T, you may experience compromised audio or static if the PEM-1000R is too close to the antenna of the PEM-1000T transmitter. Always operate the receiver at least 6 ft (2 m) away from the transmitter antenna.) 12
