1. INTRODUCTION Thank you for choosing the Nady U-800 wireless system, and congratulations on your choice. The U-800 has the best performance and price value in professional UHF wireless, offering clear-channel, frequency-agile operation on the UHF band for interference-free performance in any application or locale. The U-800 delivers 800 user-selectable, frequency synthesized channels in the US frequency band 470MHz- 490MHz.
UH-800 HANDHELD MIC TRANSMITTER • Sleek metal housing with internal antenna for optimum aesthetics and durable long life • Features the Nady DM -10D unidirectional neodymium dynamic cartridge for optimum true sound, maximum feedback rejection and minimal handling noise • 800 easily selectable channels via IR Sync download for easy synchronization with receiver’s selected channel...

INPUT JACK Locking 3.5mm mini-jack for connecting audio input cord from lapel mic (LT), Headmic™ (LT/HM), or instrument (GT) cable 40. AUDIO MUTE slide the switch to ON or OFF to mute audio with transmitter powered on 41.
The power LED and the backlight on the LCD will be off indicating the receiver is off. At power-off the U-800 receiver will store the last set- tings entered and re-display them at power-on. It can be reprogrammed to any new Group/Channel, or Mute level.
DISPLAY (5) will now light and the receiver is operational. Adjusting Antennas The U-800 has two permanently attached, flexible elbow ANTENNAS (3) for diver- sity reception. Unfold and rotate these antennas to operate the receiver. The optimal positions of the antennas are flared 45° out from the receiver sides and 90° from each other.
Audio Level and Peak LED Indicator SYSTEM OpERATION The U-800 receiver has a 5 bar AF LCD (7) display that typically shows a few bars indicating normal level audio signal from the transmitter. Occasional flickering of the fifth AF LCD (peak level) on loud inputs to the transmitter is normal. If the AF LCD lights up full bars continuously decrease the input audio level to the transmitter or overload distortion may result.

The microphone is now ready to use. The diversity A/B INDICATORS (9) on the U-800 receiver should now be on, indicating a received signal from the transmitter. When ready to speak, slide the AUDIO MUTE (36) to the ON position. The MUTE ICON (6) on receiver should be off.

Note: : The windscreen of the UH-800 functions as a built-in antenna. For proper operation, never remove the windscreen during use, or exchange with another type. For optimum range maintain line-of-sight between the transmitter and the receiver whenever possible. Holding the microphone tightly, bridging across the windscreen and Mic tube, will also lessen range.

The microphone is now ready to use. The diversity A or B INDICATORS (9) on the U-800 receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position.
Connecting Input Audio Source Lapel/Head Mic Uses (UB-800 LT/HM) The mini 3.5mm locking INPUT JACK (39) is for connecting the audio input from a lavaliere/lapel Mic (LT), a Head Mic™ (HM), or an instrument (GT) cable, depending on which transmitter version is being used. Secure the connection to the cable by tight- ening the cable mini plug’s outer ring counterclockwise.

This facilitates easy setup by enabling quick selection of stored channels for any group, i.e, selecting any group will automatically display the last channel selected for that group. See section “11. U-800 Frequency Lists” for available channels in each group. The previous group and channel used is stored in memory automatically when receiver and transmitter are turned off after operation.

Instructions for Setup of Simultaneous Multichannel Operation This U-800 receiver is capable of finding an open channel with its autoscan capabil- ity. This built-in feature is a quick, convenient way to set up many wireless systems at the same location for simultaneous multichannel operation.

If receiving interference on a selected channel with the transmitter off, or if you en- counter interferences in operating multiple U-800 systems simultaneously at the same location see: “6. Selecting Group/Channel, IR Programming and Simul- taneous Multichannel Operation”...
8. MISCELLANEOUS TIpS • The receiver antennas should be kept away from any metal surfaces whenever possible as they can reflect away or shield the incoming RF signal. • If the receiver’s volume control is set too high, it may overdrive the input of the attached audio mixer, causing distortion.
