5. SYSTEM OPERATION U-800 RECEIVER Button Function The POWER ON Button (1) is used to power receiver ON or OFF. When the power button is pressed, the POWER LED (2) and the white backlight on the LCD DISPLAY (5) will light up indicating the receiver is ready. Press the Power button again to turn off the receiver. 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

Powering the Receiver Plug the AC/DC ADAPTER (23) provided into the DC INPUT JACK (20) on the back of the receiver. Then plug the power supply into an AC outlet. (Note: Any 22V DC source with 400mA capability can also be used.) Press the POWER SWITCH (1) once to turn on the receiver. The POWER ON LED (2) and the LCD 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. Unf

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. Connecting the Audio Output The U-800 receiver has two type of outp

Programming the U-800 to the Selected Group/Channel (frequency) The Receiver must be programmed for a Group/Channel (frequency) first then auto- matic synchronization using the IR ASC™ Sync function to the transmitter. For system set up procedures, see next section “6.

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. Hold by the Mic tube housing only for optimum operation. Note: Observe care in selecting P.A. volume, transmitter location and spe

To preserve battery life, turn the transmitter off when not in use. To turn the transmit- ter off, slide the POWER ON/OFF (42) switch to the OFF position. The BATTERY STATUS LED (41) is not lit up, indicating the unit is off. The MUTE ICON (6) on receiver should be on, muting the audio out. At power off the transmitter will store the last settings entered and re-display them at the next power on. The default factory setting is Group 11, Channel 01. For optimum performance, an INPUT VOLUME LEV

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. When ready to play, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position to un-mute the audio. Adjust the INPUT VOLU

after receiver is powered off. 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. Selecting a different group on the receiver in subsequent use will d

Receiver/Transmitter ASC™ IR Sync Manual Programming To manually program the pre-selected Group/Channel (frequency) from the receiver to the transmitter, place the transmitter’s IR RECEPTOR SENSOR WINDOW (37, 44) 6-12” away from the receiver’s IR WINDOW (4). Press the MENU BUTTON (18) four times to the IR Screen Display and then press the UP BUTTON (16) to start IR programming. The flashing IR INDICATOR (10) icon indicates IR transmis- sion is in progress. When the synchronization is complet

7. CAUTIONS AND TROUBLESHOOTING Feedback Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement. Please also note the pickup pattern characteristics of the microphone selected. Unidirectional microphones are more resistant to feedback. However, they pick up sound sources best that are directly in front of the microphone. Also, mics that are farther from the sound source (such as a handheld) require more acoustic gain

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. Conversely, if the output is set too low, the overall signal-to-noise ratio of the system may be reduced, causing noticeable hiss. If such noise occurs, adjust the output level of the receiver so tha
