8 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 DISPLA Y (5) will light up indicating the receiver is ready . Press the Power button again to turn of f the receiver .
9 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 .
10 SYSTEM OPERA TION Audio Level and Peak LED Indicator 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.
11 Programming the U-800 to the Selected Gr oup/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.
12 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.
13 T o preser ve batter y life, tur n the transmitter off when not in use. T o turn the transmit- ter off, slide the POWER ON/OFF (42) switch to the OFF position. The BA TTER Y ST A TUS LED (41) is not lit up, indicating the unit is off. The MUTE ICON (6) on receiver should be on, muting the audio out.
14 Connecting Input Audio Source Lapel/Head Mic Uses (UB-800 L T/HM) The mini 3.5mm locking INPUT JACK (39) is for connecting the audio input from a lavaliere/lapel Mic (L T), a Head Mic™ (HM), or an instrument (GT) cable, depending on which transmitter version is being used.
15 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.
16 Receiver/T ransmitter ASC™ IR Sync Manual Pr ogramming T o 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) .
17 Feedback Avoid acoustic feedback (howling or screeching) by taking care in selecting P A volume, transmitter location and speaker placement. Please also note the pickup pattern characteristics of the microphone selected. Unidirectional microphones are more resistant to feedback.
18 • 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 distor tion.
