4.1. Automatic Channel Targeting (ACT) Synchronization

The ACT function allows for quick and precise frequency synchronization between the receiver and transmitter.

1. Receiver Channel Selection: On the ACT 311B receiver, use the UP/DOWN buttons to select the desired group (GRP) and channel (CH).
2. Activate ACT: Press the ACT button on the receiver. The display will show "ACT" and an infrared signal will be emitted.
3. Align Transmitter: Position the ACT-32T transmitter's infrared sensor (usually located near the display) in front of the receiver's ACT window (infrared port).
4. Mmekọrịta: The transmitter will automatically synchronize with the receiver's frequency. The transmitter's display will update to show the new group and channel.

4.2. Adjusting Transmitter Settings (ACT-32T)

The ACT-32T allows adjustment of input sensitivity and RF output power.

• Mmetụta ntinye: Press the MODE button to cycle through settings. When "GAIN" or "INPUT SENS" is displayed, use the SET button to adjust the input sensitivity for your microphone or instrument. This optimizes the audio level and prevents distortion.
• Ike mmepụta RF: Similarly, navigate to the "RF POWER" setting. Use the SET button to select between 10mW and 50mW output power. Higher power (50mW) provides greater range but consumes more battery.
• Mechie ọrụ: The ACT-32T features a mute switch. Toggle this switch to temporarily silence the audio transmission without powering off the unit. The LCD will indicate the mute status.

5. Nlekọta

• Nhicha: Use a soft, dry cloth to clean the surfaces of the receiver and transmitter. Avoid using liquid cleaners or solvents.
