Battery Removals and InstallationOpen the upper grille and capsule module, then turning the battery pack in a counterclockwise direction in order to replace the battery (see diagram 2). To reinstall the battery module after loading the new battery, turn it in a clockwise direction (see diagram 2).**NOTE: When microphone is not in use, please turn the power off. Battery pack can be recharged while in the transmitter or remove from transmitter and charged alone.343. Rear Cap On/Off Switch ProtectionThe patented color rear cap serves two purposes, provides easy channel identification and protecting the toggle on/off switch. It allows 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 cover the on/off switch completely.**Note: When using the microphone, the color rear cap must be in place.ARFAFBBTMode Switch: To select from different menuFunction Selection:The LCD panel has 6 functions displayed sequentially; their respective descriptions and operations are as follows:a. Press MODE (7) to access the 6 different functions. Once a function is selected, it starts flashing on the screen. If parameter needs to be modified on selected function, press SET (8) to modify the value while the display is still flashing. Once done, leave it for 5 seconds until it stops flashing and the selection will be programmed into the transmitter.A.

**NOTE: When program a special frequency via monitoring software; LCD screen cannot display the number. This is because this special channel is not in the preset group and channel. Therefore, LCD panel will look like illustration below.**NOTE: To modify transmitter's group, channel and frequency, all three must be set at the receiver and transmit the new setting to transmitter via ACT.56(1)GR-CH: Displays Information of Group and ChannelRFRFAFAFBTBTRFRFAFAFBTBT5B.

Meanwhile the danger of unwanted noises and feedback getting into the system would obviously rise. 2. It is advisable to generally set the sensitivity to a level between 0dB-6dB.3. When set at 0 dB, the maximum SPL for handheld microphone is 145dB.**NOTE: When the LIMIT is ''ON'', the maximum output of the receiver is limited to 1V.**NOTE: "ENCRYP" function is added to display status information only. Changing of current status must be done from receiver via ACT.DIGITAL WIRELESS HANDHELD MICROPHONE DIGITAL WIRELESS HANDHELD MICROPHONE
5. Cautions1. Unless necessary, do not remove the battery module from the microphone when the microphone needs to be charged. The best way is to put the whole microphone into the charger for recharging; this prolongs life of contact spring on the capsule module. 2. Traditionally designed microphones have an antenna protruding on the bottom of the housing. Modern designs have a built-in antenna in the upper or lower housing. Antenna section of ACT-8H is located on the end of the transmitter (where the color cap is). Users should avoid holding the microphone over or near antenna section as this will deteriorate transmission efficiency, and deterioration gets even more severe if users hold the microphone directly above the antenna with both hands.. 3. Many performers tend to hold the microphone by the grille. Unfortunately, this position seriously degrades both the sound quality and directionality of a microphone. Even the most expensive microphone 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.4. 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.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.910BT BT BT BT BT7.
