OPERATING INSTRUCTIONS FOR INSERTION & REMOVING BATTERY(Figure 2)1. Gently twist the microphone housing in a counter-clockwise direction.2. Remove the old batteries from the battery compartment, if any are installed.3. Insert two new AA alkaline batteries in the battery compartment with correct polarity orientation. If normal, the red LED indicator will light solid for a second after the transmitter is turned-on. Fasten the microphone housing when done. 4. In the case of low battery, the red LED indicator will stay illuminated. Change to new fresh batteries.5. In the case of dead battery, the red LED indictor will not be illuminated.OPERATING INSTRUCTIONS1. The red LED indicator will light solid for a second and the RF level/indicator shown on the receiver will remain illuminated after the transmitter is turned-on, denoting normal status. No illumination in the red LED indicates an incorrect battery polarity insertion, dead batteries or malfunction. 2. The audio level or indicator show on the receiver will be lit when there is audio line or microphone input from the transmitter. CAUTIONRemove the batteries if unused for a long period of time to prevent battery leakage, corrosion and causes damage to electronics.Handheld Transmitter Handheld Transmitter4 57
GENERAL TIPS FOR IMPROVING SYSTEM PERFORMANCE4. Furthermore, a large-diaphragm directional microphone has a very distinct proximity effect. When the microphone is close to the mouth, the bass response is strengthened as the distance gets closer. Therefore, if a performer's sound is insufficient in bass, they can hold the microphone closer and use the proximity effect to help compensate for the lower bass level. Conversely, if a performer's voice is too heavy in the bass register, increasing the distance between the microphone and their mouth will decrease the proximity effect and reduce the bass response, thus making their voice become clearer and brighter.5. It is recommended to keep the grille and sponge windscreen clean to avoid any substance blocking the proximity effect of the microphone.1. Performer should avoid holding the microphone over or near the antenna section as this will deteriorate transmission efficiency. Severe deterioration if performer directly covers up the antenna section with both hands. 2. Many performers tend to hold the microphone by the top grille. Unfortunately, this position seriously degrades both the sound quality and directionality of a microphone. Even the most expensive microphones will have its original sound quality compromised by this method. Grabbing a microphone by the grille will isolate the capsule's acoustic resonance circuit and or change the capsule resonator's frequency. This results in an inferior performance in both frequency response and the separation of directionality. In addition, a palm's sound-focusing effect will tend to strengthen resonances in certain frequencies and can cause unwanted echo.3. A proper technique is required for using directional microphones because the distance between the microphone and your mouth has a significant impact on sensitivity and performance. There is an inverse relationship between microphone sensitivity and the distance from the mouth to the microphone. Consequently, performers with a ''weaker'' sound level cannot expect to hold the microphone too far away from their mouth and compensate by turning up the amplifier volume to increase the sound level as this can easily cause echo or feedback. In contrast, performers with a ''louder'' sound level should not hold the microphone too close as this can easily result in distortion by causing the amplifier system to be overloaded.Handheld Transmitter Handheld Transmitter6 7Disposal2005-08 -132005-08 -13Dispose of any unusable devices or batteries responsibly and in accordance with any applicable regulations.Disposing of used batteries with domestic waste is to be avoided!Batteries / NiCad cells often contain heavy metals such as cadmium(Cd), mercury(Hg) and lead(Pb) that makes them unsuitable for disposal with domestic waste.
