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 speaker placement so that acoustic feedback (howling or screeching) will be avoided.
Operating the UH-800 Handheld Transmitter
The RF POWER (35) and the AUDIO MUTE (36) switches have two positions for power ON/OFF and audio mute ON/OFF respectively. During normal operation with the unit powered on standby, slide the RF POWER (35) switch to the ON posi- tion. You will feel a slight click indicating the ON position is selected. The receiver’s RF Indicator (8) and diversity A/B INDICATOR (9) should now be on, indicat- ing a received RF signal from the transmitter. When ready to transmit audio, slide the AUDIO MUTE (36) to ON to un-mute. To mute, slide the switch to OFF again. Ad- just the volume of the receiver per the previous section, Connecting the Audio Output.
Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.
Programming the UB-800 to the Selected Group/Channel (frequency) The transmitter must be programmed to the same frequency as selected for the re- ceiver via automatic synchronization using the IR ASC™ Sync function. It can not be programmed on the transmitter itself. See in next section “6. Selecting Group/
Channel, IR Programming and Simultaneous Multichannel Opera- tion”.
UB-800 BODYPACK MICROPHONE TRANSMITTER (LT, HM OR GT)
Setting up the UB-800 Transmitter
The UH-800 requires two AAA alkaline or NiMH batteries to operate (do not mix types). To install the batteries, lift the LATCHING BATTERY DOOR (46) and open up, exposing the BATTERY COMPARTMENT (45). Insert two fresh AAA batteries according to the polarity indicated on the transmitter body. Close the battery cover back onto the microphone, making sure it is secure. Fresh alkaline batteries can provide up to 8 hours of operation, but in order to ensure optimal performance it is recommended that the batteries be replaced after 4-6 hours of use or as indicated necessary by the BATTERY STATUS LED (41) lit RED.
Powering the UB-800 Transmitter On/Off
Turn on the UB-800 by sliding the AUDIO MUTE (40) to the OFF position first. Then slide the POWER ON/OFF (42) to the ON position. The BATTERY STA- TUS LED (41) will stay on GREEN and the transmitter is now on, indicating usable battery strength. In the case of a dead or low battery, the LEDs will not go on at all or the BATTERY STATUS LED (41) will stay on RED continuously, indicating that the batteries should be replaced with fresh ones.
