Ascertain the battery is inserted according to its Operating Instructions Transmitter Transmitter correct polarity. A click is heard once correctly inserted and grill can be closed properly. No click is heard and grill cannot be closed properly if battery is inserted with the wrong polarity. NOTE:
Transmitter cannot be powered on with a charged battery. a. Check for correct polarity insertion.
(+ facing up) b. If inserted with correct polarity and still cannot be powered on it could be due to battery protection mechanism is in effect. Insert the whole transmitter back to the battery charger for 10 seconds to wake-up and power on again. c. If battery charger is not used, reverse battery polarity for 10 seconds and then re-inserted with correct polarity to wake up the battery. Power on again. 1. Power On & Off a. Power On: Push the ON/OFF switch to the
"ON" location, the battery indicators will light. b. Power Off: Push the ON/OFF switch back, the battery indicators will go out. 2. Battery Status Display a.

(red indicator) 4 5 Transmitter Transmitter Rear Cap has an On/Off Switch Protection The patented color rear cap serves two purposes; it provides easy channel identification and protects the on/off switch. It is designed to allow the on/off switch to either be exposed or concealed as desired. You can avoid unintended switching off of the microphone by rotating the color rear cap 180 degrees to fix the on/off switch. The cap can be removed by gripping it firmly and pulling; be sure to push it firmly into place when replacing it on the microphone. Note: During microphone usage, the color rear cap must be installed. Press both sides and pull out to remove the rear cap General Tips for Improving System Performance 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 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. 4. Furthermore, a large-diaphragm directional microphone Turn the rear cap 180 degree and insert back The ON/OFF switch is immovable 5. 7 6 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. It is recommended to keep the grille and sponge windscreen clean to avoid any substance blocking the proximity effect of the microphone.
