User manual NADY WS-16U

[. . . ] SERVICE (U. S. ) Should your Nady Wireless Microphone System require service, please contact the Nady Service Department via telephone at (510) 652-2411 or e-mail to service@nady. com for a Return Authorization (R/A) Number and a service quote (if out of warranty). Make sure the R/A Number is clearly marked on the outside of the package and enclose a cashier's check or money order (if not prepaid with a credit card). Ship the unit prepaid to: Nady Systems, Inc. , Service Department, 6701 Shellmound Street, Emeryville, CA 94608. Include a brief description of the problems you are experiencing. [. . . ] If, with the transmitter off, the receiver's A or B DIVERSITY LED INDICATORS (14) flicker or stay on, the squelch control should be turned counterclockwise until the A or B LEDs extinguish. When the squelch is properly adjusted, the A or B LEDs will only light when the system transmitter is turned on. Turning the squelch control too far counterclockwise will reduce the range, but yield a quieter squelch (mute) function. During operation, especially at ranges greater than 75 feet, the A or B LEDs may alternate briefly. This is normal unit's DigiTRU DiversityTM reception feature that ensures the received audio will not be interrupted. When both LEDs extinguish, the transmitter is out of range for that given location, and the user should move closer to the receiver to re-establish the radio link. (Note: The BT-16U is supplied with a removable antenna. It should be operated with the supplied antenna all times. For optimum operating range, always maintain line-of-sight between the transmitter and the receiver whenever possible. ) (Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or connections are used with any wireless system. Therefore, the supplied INSTRUMENT CORD (40) has a factory-installed capacitor inside the 1/4" plug. This capacitor provides first order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still give you scratchy noises, we suggest these steps to eliminate them:) a. Make sure all guitar volume and tone pots are clean and all contacts are solid as this is very important. A 47pf capacitor soldered across the hot to ground terminals of the guitar's volume and tone pots will provide extra filtering. Microphone Use (with either a lavalier or head-worn microphone) Secure the connection from the HEADWORN (41) or LAVALIER MIC CORD (42) by turning clockwise the slip ring on the plug into the transmitter to thread it on to the jack. 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 head-worn 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, slide the AUDIO SWITCH (34) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above WS-16U receiver instruction [Note: 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. [. . . ] (IMPORTANT NOTE: The transmitter must be OFF when selecting a new channel. When selected, the transmitter will then be at the new selected channel when turned ON. If you attempt to change the channel when the transmitter is ON it will not change until the unit is turned OFF and ON again. This step must be repeated any time for selecting a new channel. ) 3.
