WLT LAVALIER/LAPEL OR HEADWORN MICROPHONE BODYPACK TRANSMITTER 1. Snap open the BATTERY COMPARTMENT (22) and insert a fresh 9V BATTERY (23), observing the correct polarity. Close the compartment. 2. The WLT is provided with a 3.5 mm LOCKING JACK (24) for connecting the microphone. Plug in either the LAVALIER/LAPEL (25) or the HEADWORN MICROPHONE (26), as supplied. To secure the connection, turn the metal slip ring on the plug clockwise to thread it on to the jack. To unplug, reverse the process. Slip the transmitter into a pocket or clip on to your clothes. To use the lavalier mic, attach it at chest level. Do not place 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 mic boom so that the mic is about one inch to the side of the front of the mouth. (Note: The lavalier or headworn mic wire is also the transmit antenna, 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 by sliding the OFF/STANDBY/ON SWITCH (27) to the STANDBY position (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 battery strength. In the case of a dead or low battery, the LED either will not go on at all or will stay on continuously, indicating that the battery should be replaced with a fresh one. 4. The microphone is now ready to use. Most or all of the RF DISPLAY LEDs (4) on the Enc-I receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the transmitter switch to the ON position and adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above Enc-I receiver instructions. The AF LEVEL LED DISPLAY (5) on the Enc-I receiver will light up to 5 LEDs (4 green and 1 red) for all input signals. Occasional flickering on and off during use of the top red LED indicator in this display is normal, however if the red LED stays on continuously, it means the signal is too loud and there is the possibility of overload distortion. Re‑ position the microphone farther from the source or adjust the AUDIO INPUT LEVEL CONTROL (29) until the red LED indicator flickers only on the loudest inputs. (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 observe the pickup patterns 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 mics that are used close to the mouth.) (Note: Microphone elements 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.) 9
