[. . . ] Experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and is not recommended. ) The microphone is now ready to use. The receiver's signal strength and diversity indicators should now be on, indicating a received signal from the transmitter. When ready to speak, press the 8 UH-1K HANDHELD MICROPHONE TRANSMITTER UH-1K's POWER button to unmute. To mute, press the Power/Mute button again. Adjust the volume of the receiver as per section 12 (UWS-1K Receiver: Connecting Audio Output). volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided. ] [Note: The RF Level Meter (12) and the Diversity Indicator (13) on the receiver are "ON" in normal use with the audio "ON" (not muted). When the transmitter is "ON" but muted, the RF Level Meter will stay "ON" but the Diversity Indicator wil be "OFF". ] (Note: The 2 AA batteries loaded into the bottom half of the UH-1K function as a built-in antenna. For proper operation and best operating range the transmitter should be held above that area so as not to hand block the antenna and lessen the transmission strength. ) 28 23 25 24 27 26 21. Input level control 21 22 UB-1K BODYPACK MICROPHONE TRANSMITTER 17. Setting up the Transmitter The UH-1K requires 2x AA size batteries to operate. To install the batteries onto the Battery Holder (30), press the "OPEN" side on the Battery Lid (29) and slide as indicated by the arrow to open the Battery Lid (29), exposing the battery holder. Insert 2 fresh AA batteries according to the correct polarity as indicated on the transmitter body. Cover the Battery Lid (29) and press on the "CLOSE" side slide as indicated by the arrow to lock the battery door securely. Fresh Alkaline batteries can last for up to 8-10 hour of operation, but in order to ensure optimum performance, it is recommended that the batteries be replaced after 6-8 hours of use. 18. Powering the Transmitter ON/OFF To turn transmitter on, press and hold the Power/Mute Button (32) for more than 2 seconds. Both LEDs IR/Audio Mute (34) and Battery Strength Indicator (33) will light up. After 20 seconds the green IR LED (34) will automatically turn off. If the audio is muted (see Section 20 below) the LED will stay lit and change to red till the audio mute is turned off (and audio signal is 9 UB-1K BODYPACK MICROPHONE TRANSMITTER back on). The Battery Level LED (33) should stay fully lit green indicating usable battery strength. This LED turns red if the batteries are low and the batteries should be replaced with new ones. To preserve battery life, turn the transmitter off when not in use.
