Battery Installation

1. ACT-70H/ACT-72H:
   • Rotate and remove microphone capsule module O counterclockwise.
   • Insert two AA-sized batteries according to their correct polarity for a proper fit.
2. If the LCD screen is not lit after being powered on, check if the battery is inserted polarity correctly or is fully drained.
3. ACT-70HC/ACT-72HC:
   • Rotate and remove microphone capsule module O counterclockwise.
   • Press both sides of Fixed Ring @ to pull out Fixed Ring.
   • Insert an 18500 rechargeable battery according to its correct polarity for a proper fit. (with minus – towards the housing) The wrong polarity will not fit properly.
   • Dock the microphone onto a MIPRO-exclusive battery charger for charging.
   • Notice :
   1. If inserted with correct polarity and still cannot be powered on it could be due to the battery protection mechanism being activated. Insert the whole transmitter back into the charging station for 10 seconds to deactivate it and power it on again.
   2. If the charging station is not used, reverse battery polarity for 10 seconds then re-inserted with the correct polarity to wake up the battery. Power on again.

Operating Instructions

1. Power On/Off:
   Slide up or down the Power Switch to power on or off. The LCD screen is lit once it’s powered.
   “OFF … ” appears during power off.

2. Battery Level Status:

   • When the battery has less than 10% power remaining (0-bar displayed), ACT-70H/ACT-72H needs to be replaced or ACT-70HC /ACT-72HC needs to be recharged. If under voltage condition continues, the screen will show “OFF … ” and the system will power off automatically.

3. Remove the protection rear cover to expose the MODE and SET buttons.

4. Press the MODE button to access one of the 5 parameters below and press the SET button to activate parameters for change.

5. LCD Display:

   • Transmitter Functions
   • Transmitter Parameters
   • Transmitter Battery Display

6. Group (GRP) / Channel (CH) / Frequency (FREQ.)

   • Group / Channel / Frequency messages are displayed only and cannot be changed.
   • To change Group / Channel / Frequency, do it at the receiver and then press the ACT button to sync.
   • For those specific channels set via PC, the screen shows only CHANNEL and numbers.

7. AF GAIN: Audio Gain

8. Adjusts audio level from 0dB to 6dB in 3dB step.

  * Press the MODE button to access the AF GAIN parameter.
  * Press the SET button and the parameter value flashes.
  * Press the SET button again and the values rotate by each press.
  * Press the MODE button to save the selected value or the value will save automatically when it stops flashing. The higher the gains, the lower the dynamic range for signal input and the greater the danger of unwanted noises and higher chances of feedback. The default value of AF Gain is 0dB.

8. RF POWER: RF Power
9. Two parameter values: RF-HI and RF-LOW.

  * Press the MODE button to access the RF POWER parameter.
  * Press the SET button and the parameter value flashes.
  * Press the SET button again and the values rotate by each press.
  * Press the MODE button to save the selected value or the value will save automatically when it stops flashing.

9. MUTE MODE: audio mute
10. Two parameters: MANUAL and DISABLE.

  * Press the MODE button to access the RF POWER parameter.
  * Press the SET button and the parameter value flashes.
  * Press the SET button again and the values rotate by each press.
  * Press the MODE button to save the selected value or the value will save automatically when it stops flashing.
2.  **MANUAL** : MUTE is controllable by pressing the external MUTE button.
3.  **DISABLE** : Mute is disabled and cannot be muted in any method.

10. Error codes:

  * ERR noo1➔ Transmitter does not have the initial programmed data.
  * ERR noo2➔ (for test) RF circuitry failure, the frequency cannot be programmed.
  * ERR no03➔ The frequency to be set exceeds the upper limit of the microphone. It cannot be synced, thus, no RF and audio transmission. Power on the microphone again to reset.
  * ERR no04➔ The frequency to be set exceeds the lower limit of the transmitter. II cannot be synced, thus, no RF and audio transmission. Power on the microphone again to reset.

11. GROUP CHANNEL: The preset frequency of the receiver.
12. Displays “CHANNEL” only: User-defined frequency of receiver and needs to be changed via PC.
13. MUTE setting:

  * Press the MUTE button to enter mute status.
  * Press the MODE and SET buttons to change other parameters, but it will return to MUTE mode after 5 seconds.

Transmitter Battery Chargers
(optional)

The transmitter (s) can be recharged by docking into an MP-8 charger.

Protection rear cover to prevent accidental power on/off

1. To prevent users from powering off the microphone accidentally, take out and reverse the protective rear cover.
2. We recommend the rear cover be installed during usage.

Cautions

1. Turn it off to save battery life when not in use. Remove the battery not used for an extended period.
2. To improve the efficiency of the transmitting antenna, do not cover the hands over the rear housing section.
3. To prevent degraded microphone sound quality, directionality, and annoying feedback, do not cover the hands over the microphone grill.
4. Correct posture of holding the handheld microphone is required because the distance between the microphone and the mouth will have a significant impact on the sensitivity and sound quality.
5. Keep the microphone grill clean and unblocked to enhance pick-up sound quality.
6. Refer to the actual product in the event of product description discrepancy.
7. Frequency range and maximum deviation comply with the regulations of different countries.
8. Spraying alcohol directly onto the condenser capsule module will cause severe damage and invalidate the warranty.
