SERVICE FOR YOUR NADY WIRELESS SYSTEM U.S. International FCC RF Exposure Statement This device complies with FCC radiation exposure limits as set forth for an uncontrolled environment. This device should be installed and operated so that its antenna(s) are not co-located or operating in conjunction with any other antenna or transmitter. Preliminary 01/02 A. INTRODUCTION Thank you for choosing the Nady UHF 16 wireless system, and congratulations on your choice. The Nady UHF 16 systems are by far the best performance and price value available in professional UHF wireless. Offering clear channel operation on the wide open, uncluttered UHF band for interference-free performance in any application or locale, the UHF 16 delivers 16 user switchable, frequency synthesized channels in pre-programmed groups in the 726 - 865 MHz range. The UHF 16 systems feature Nady's proprietary companding and low noise circuitry for an industry best 120 dB Dynamic Range, and the clearest, most natural sound available in wireless today. Using this Manual This booklet gives instructions for the operation of the UHF 16 systems, including the UB-16 Bodypack Transmitter, and the UH-16 Handheld Microphone Transmitter. Please read this instruction booklet completely before operating your system, and refer to the Nady UHF 16 Frequency Guide for the frequency band(s) and channels utilized by your system. This manual will first explain the benefits of the UHF 16 and then will take you step by step on how to operate your new system. Each section will give you detailed information. Also, included in this manual is the frequency selection chart, complete system specifications, and servicing information. B. SYSTEM FEATURES UB-16 Transmitters Choice of transmitters: UH-16 handheld or UB-16 bodypack, both 16-channel selectable • UB-16 operates on 2 AA batteries for the longest reliable and economical battery life. • UB-16 bodypack is a versatile unit with unique 3-way input switch allowing it operation selectively as an instrument, lavalier mic, or headworn mic transmitter (with convenient DC phantom powering in the mic settings for condensers). An input level control allows optimal audio gain adjustment, and a locking 3.5 mm jack provides secure connection to the instrument cable, lavalier or headworn mic cord. • UB-16 transmitters features OFF/STANDBY/On controls, low battery LED indicators, and offer easy channel selection via UP/DOWN buttons and a 2- segment LED Channel display. C. OPERATING INSTRUCTIONS UB-16 Bodypack Transmitter 1. Powering the Transmitter Slide open the BATTERY COMPARTMENT (19) and insert 2 fresh AA ALKALINE BATTERIES (20), observing the correct polarity. AA AA Preliminary 01/02 Two fresh alkaline batteries can last up to 12 hours in use, but in order to ensure optimum performance, it is recommended that the battery be replaced after 8-10 hours of use. 2. Selecting Input for Operation The UB-16 is equipped with an INPUT SELECTOR SWITCH (21) in the battery compartment for selecting the type of audio input you will be supplying to the transmitter. Select from the choice of three positions: GT (for guitar, bass, etc.) / HM (for headworn mic)/ LT (for lavalier mic). 3. Connecting the Audio Source The UB-16 is provided with a 3.5 mm LOCKING JACK (22) for connecting the audio input selected. Connect either the INSTRUMENT CORD (23) or the HEADWORN MIC (24) or LAVALIER MIC CORD (25) as desired, according to the input selected. (Note: Use only the input audio source as per the input selected with the AUDIO INPUT SELECTOR SWITCH or the audio will not be optimal– a muddy or distorted sound may result.) To secure the connection, turn the slip ring on the plug clock wise to thread it on the jack. To unplug, reverse the process. Slip the transmitter into a pocket or CLIP (26) it on to your clothes or instrument strap (if using the UB-16 as an instrument transmitter). 4. Turning on the Transmitter Turn on the UB-16 by sliding the OFF/STANDBY/ON SWITCH (26) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (27) will give a single quick flash, indicating usable battery strength. In the case of dead or low batteries, the LED either will not go on at all or will stay on continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life; turn the transmitter off when not in use. Inside the cover, the channel number on the CHANNEL LED DISPLAY (29) will extinguish in 10 seconds. The activity indicator “ “ or “ “ LED will remain on. 5. Selecting the Operating Frequency In order for the system to operate properly the same channel (frequency of operation) must be selected for the UB-16 transmitter as was chosen for the UHF-16 receiver. Press either the UP or DOWN CHANNEL SELECT BUTTON (28) until the channel number indicated on the 2-segment CHANNEL LED DISPLAY (29) matches that of the UHF- 16 receiver. 6. Selecting the Tone Squelch™ Mode Hold both the UP and DOWN BUTTONS (28) at the same time for 1 second. The Tone Squelch™ will cycle from On to Off. See the CHANNEL DISPLAY AND UP/DOWN BUTTON OPERATION section below. 7. Locking the K…
