3. Rear Cap On/Off Switch Protection
The 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.
Open 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).

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

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.

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.
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..
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.
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.
It is recommended to keep the grille and sponge windscreen clean to avoid
any substance blocking the proximity effect of the microphone.
