Handheld Transmitter Handheld Transmitter0 1ProfileThere are two types of antenna design for the handheld transmitter microphones “built-in” and “external”. The “built-in” design is normally incorporate upper side of PCB in the housing and the microphone capsule module as transmitting antenna. The advantages are to avoid the antenna breakage due to external design, inconvenience and able to shorten the microphone housing design. However, its drawbacks are poor transmission efficiency especially when replacing microphone capsules, unstable and deteriorated transmission efficiency if it is gripped over the antenna area. The “external” design enhances transmission efficiency and stability, however, it causes inconvenience and it may be damaged by accidental crashing. MIPRO's patented design provides an ideal solution. The antenna is integrated in the battery holder at the bottom side of the housing, so it successfully combines the advantages of both “built-in” and “external” design. The matched antenna and transmitter circuit enhance transmission efficiency and stability regardless capsules and battery replacement, or change of grip positions and housing materials.Microphone capsule, audio modulation, RF output and antenna transmission constitute the perfect straight-line layout of the transmitter PCB so that it can achieve the best transmission quality and efficiency. ACT-30H/30Hr are the most evolved design model for built-in antenna transmitters nowadays.1 Profile2 Key Features3 Handheld Controls and Indicators5 O 9 General Tips for Improving System Performanceperating Instructions for Insertion & Removing Battery6 Operating Instructions7 Lcd Screen8 Battery StatusContents

ERRGROUPCHANNELBAT!ERR Message: When “ERR” appears in the display it indicates that an operational error has occurred. Please refer to the following codes to diagnose which error you are experiencing.ERR no01 EEPROM is not being programmed or internal data error.ERR no02 For testing only.ERR no03 The frequency you want to program is above the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed "ERR" message, switch the handheld transmitter off and on again.)ERR no04 The frequency you want to program is below the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed “ERR” message, switch the handheld transmitter off and on again.)!“Group” & “Channel” : When both the group and channel numbers are displayed, it means that you are using the pre-programmed frequency of the receiver.!“Channel” Only : If “Channel” only is displayed, it means that you are using a frequency which is not pre-programmed.Handheld Transmitter Handheld Transmitter6 7Operating instructions1. LCD screen on the transmitter and the RF level/indicator shown on the receiver will be lit when the microphone is turned-on, denoting normal status. A blank LCD screen maybe due to an incorrect battery polarity orientation. 2. The audio level or indicator show on the receiver will be lit when there is audio line or microphone input from the transmitter. CautionRemove the batteries if unused for a long period of time to prevent battery leakage, corrosion and causes damage to electronics.LCD Screen
General tips for improving system Performance1. 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.Handheld Transmitter Handheld Transmitter8 9Indicates the power remaining in the transmitter battery. When the battery has less than 10% power remaining it must be replaced or recharged. If an under voltage condition continues, the LCD will show “Poff” and the system will shut down to prevent being overly discharged.“Poff” - Power Off : 100% 80% 40% 10% 0%When the power switch is turned off, the LCD will show “Poff” (for Power Off) first and then the system will shut down and no further messages will be displayed.Battery Status
