WLT-15 LAVALIER/LAPEL OR HEADWORN MICROPHONE BODYPACK TRANSMITTER1. Snap open the BATTERY COMPARTMENT (22) and insert a fresh 9V BATTERY (23),observing the correct polarity. Close the compartment.2. The WLT-15 is provided with a 3.5 mm LOCKING JACK (24) for connecting the micro-phone. Plug in either the LAVALIER/LAPEL (25) or the HEADWORN MICROPHONE (26), assupplied. To secure the connection, turn the metal slip ring on the plug clockwise to threadit on to the jack. To unplug, reverse the process. Slip the transmitter into a pocket or clipon to your clothes. To use the lavalier mic, attach it at chest level. Do not place too closeto the mouth-a distance of about six inches usually works best. To use the headworn mic,place it on the head and adjust the mic boom so that the mic is about one inch to the sideof the front of the mouth. (Note: The lavalier or headworn mic wire is also the transmitantenna, and rolling up or shortening the wire may reduce the effective operating range.Extend the wire fully during use, and keep it as straight as possible.)3. Turn on the WLT-15 by sliding the OFF/STANDBY/ON SWITCH (27) to the STANDBYposition (transmitter on, audio muted) or the ON position (transmitter and audio both on).The BATTERY INDICATOR LED (28) will give a single quick flash, indicating usable batterystrength. In the case of a dead or low battery, the LED either will not go on at all or willstay on continuously, indicating that the battery should be replaced with a fresh one.4. The microphone is now ready to use. The A and/or B DIVERSITY LED INDICATORS (8)and most or all of the RF DISPLAY LEDs (9) on the XR-61 receiver should now be lit, indicat-ing a received signal from the transmitter. When ready to speak, slide the transmitter switchto the ON position and adjust the volume of the receiver as per the Audio OutputMicrophone Connection section of the above XR-61 receiver instructions. The AF LEVELLED DISPLAY (13) on the XR-61 receiver will light up to 5 LEDs (4 green and 1 red) for allinput signals. Occasional flickering on and off during use of the top red LED indicator inthis display is normal, however if the red LED stays on continuously, it means the signal istoo loud and there is the possibility of overload distortion. Re-position the microphone far-ther from the source or adjust the AUDIO INPUT LEVEL CONTROL (29) until the red LEDindicator flickers only on the loudest inputs.[Note: Observe care in selecting P.A. volume, transmitter location and speaker placementso that acoustic feedback (howling and screeching) will be avoided. Please also observethe pickup patterns of the microphone selected: omnidirectional mics pick up sound equallyfrom all directions and are prone to feedback if not used carefully. Unidirectional mics aremore resistant to feedback, but pick up sound sources best that are directly in front of themic. Also, mics that are farther from the sound source, such as lavaliers, require moreacoustic gain and thus are also more prone to feedback than close-source mics such ashandheld or headworn mics that are used close to the mouth.](Note: Microphone elements can easily be destroyed by the buildup of salts and mineralsfrom perspiration and saliva. It is good practice to put a windscreen on the mic element atall times to protect it.)1025222429282722232611
