OPERATING INSTRUCTIONS
UB-16 Bodypack Transmitter

b. Microphone Use (with either a lavalier or headworn microphone) Secure the connection from the LAVALIER (33) or HEADWORN MIC (34) cord by turning the slip ring on the plug into the transmitter clockwise to thread it on to the jack. To unplug, reverse the process. To use the lavalier mic, attach it at chest level. Do not place it too close to the mouth�a distance of about six inches usually works best. To use the headworn mic, place it on the head and adjust the boom so that the mic is about one inch to the side of the front of the mouth.
When ready to speak, verify that the INPUT SELECTOR SWITCH (23) is in either the HM position (for a connected headworn mic) or the LT position (for a lavalier mic) and slide the OFF/STANDBY/ON SWITCH (28) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the preceeding UHF-16 receiver instructions. For optimum performance, an INPUT LEVEL CONTROL (26) is provided. Adjust the gain by turning the control with the supplied small slotted screwdriver. For lavalier mic use, it is recommended that the level be set at about 2/3 maximum. For headworn mic use, it may be advisable to turn the gain down somewhat, depending on the volume levels expected. In either application, 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.)

Cautions

a. Feedback Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback, howling and screeching, will be avoided. Please also note the pickup pattern characteristics of the microphone selected. Omnidirectional mics pick up sound equally from all directions, and are prone to feedback if not used carefully. Unidirectional mics are more resistant to feedback, but pick up sound sources best that are directly in front of the mic. Also, mics that are farther from the sound source, such as lavaliers, require more acoustic gain and thus are also more prone to feedback than close-source mics such as handheld or headworn models that are used close to the mouth. b. Microphone Damage The headset or lavalier microphone element can easily be destroyed by the buildup of salts and minerals from perspiration and saliva. It is good practice to put a windscreen on the mic element at all times to protect it. c. No Audio If the receiver is configured for Tone Squelch� mute, the transmitter must also be configured to send the tones, otherwise the receiver audio will remain muted. See preceding Mute Adjustment section, page 8.
