UH-4 Handheld Microphone Transmitter

1.Unscrew the BATTERY COMPARTMENT COVER (16) and remove, exposing the BATTERY HOLDER (17). Insert a fresh 9V ALKALINE BATTERY (18), observing the correct polarity as marked, and screw the cover back on to the microphone. Make sure the cover is screwed on completely. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that you replace the battery after every 6-8 hours of use.

2.Turn on the UH-4 by sliding the OFF/STANDBY/ON SWITCH (19) to the STANDBY position first (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (20) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED will either not go on at all or will stay on continuously, indicating that the battery should be replaced with a fresh one. To preserve battery life, turn the transmitter off when not in use.

3.The microphone is now ready to use. The A or B DIVERSITY LED INDICATORS (13) on the UHF-4 receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the OFF/STANDBY/ON SWITCH (19) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above UHF-4 receiver instructions.

[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided.]

4.For optimum performance, an INPUT LEVEL CONTROL (21) is provided. Adjust the gain by turning the control with a small screw driver. 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.)
