The portable receiver and transmitter are equipped with a programmable automatic shutoff timer which, upon expiration will turn off. ! The shut-off timer is pre-programmable with MIPRO PC interface software and is currently factory set for a duration of 6 hours (360 minutes). ! Thirty (30) seconds before the shut-off timer elapses a TIME OUT message will appear on the LCD screen and then it will be powered off automatically to conserve the battery. MANUAL MANUAL AF MUTE 12 13 Handheld Transmitter 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 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. 14 Handheld Transmitter 4. 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. Notes 1. Refer to actual product in the event of product description discrepancy. 2. Frequency range and maximum deviation comply with the regulations of different countries. 15 FCC FCC Radiation Exposure Statement Federal Communication Commission Interference Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.

Disposing of used batteries with domestic waste is to be avoided! 2005-08-13 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. You may return spent batteries/ accumulators free of charge to recycling centres or anywhere else batteries/accumulators are sold. By doing so, you contribute to the conservation of our environment!
