When the battery level drops down to 10%, please replace or recharge the battery. If the battery continues to be used at a very lower level, the LCD will display and then automatically switch off to avoid over-discharging the

"PO--OFF"

battery.

8. ERR: Error Code

If the LCD displays ''ERR'' after turning on the power, it indicates the operation is not correct. The error codes are as follows:

ROM-ER Transmitter does not have the initial data so the

microphone is completely dead.

ERROR1 Failure on RF circuitry, frequency can not be

programmed.

NO----O3 Frequency to be programmed into the transmitter

exceeds its highest frequency of designated frequency band of the transmitter.

NO----O4 Frequency to be programmed into the transmitter

exceeds its lowest frequency of designated frequency band of the transmitter.

**NOTE:

NO----OR3 and NO----OR4 will not change transmitter's original frequency, and the transmitter still operates normally with error message on display.. To remove error message from display panel, please switch off the transmitter and switch it on again.

(9) PO-OFF: System Turning Off

When the power is turned off, the LCD displays ''PO-OFF'' indicating the system is at the state of shutting down and then automatically cuts the power off. The display panel has no further message afterward.

5. Cautions

1. 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.
