5.2 Transmitter Setup

Battery Installation: Open the battery compartment of each bodypack transmitter. Insert two 1.5V AA batteries, ensuring correct polarity. Close the compartment securely.
Microphone Connection: Plug the lavalier or headset microphone into the input jack on the bodypack transmitter.
Power On: Turn on the power switch on the bodypack transmitter. The LCD display will illuminate, showing the channel and battery status.

6. Operating Instructions

Powering On the System: First, power on the receiver. Then, power on each bodypack transmitter.
Volume Adjustment: Use the individual volume control knobs on the receiver for each channel (CH 01, CH 02, CH 03, CH 04) to adjust the microphone levels. Start with the volume low and gradually increase it to avoid feedback.
Signal Indicators: The receiver's LCD display will show the active channel frequencies. The RF (Radio Frequency) and AF (Audio Frequency) indicators will light up when a signal is being received and audio is present, respectively.
Usage: Position the lavalier microphone approximately 6-8 inches from your mouth, or wear the headset microphone comfortably. Speak clearly into the microphone.
Powering Off: When finished, first turn off the bodypack transmitters, then power off the receiver. This helps prevent pops or thumps through your sound system.

7. Maintenance

Cleaning: Use a soft, dry cloth to clean the receiver and transmitters. Do not use liquid cleaners or solvents.
Battery Replacement: Replace batteries in the bodypack transmitters when the low battery indicator appears on the LCD display. Always use fresh, high-quality 1.5V AA batteries.
Storage: Store the system in a cool, dry place when not in use. Remove batteries from transmitters if storing for extended periods to prevent leakage.
Antenna Care: Handle antennas carefully. Avoid bending them excessively.
