Using the Audio Technica ATW-901a/L is a breeze. First, connect the receiver to a power source using the provided power supply. Make sure it's plugged into a stable 100 - 240V AC outlet. Then, turn on the receiver and select the appropriate VHF channel from the four available options (169.505, 170.245, 171.045, and 171.905 MHz). This helps you avoid interference and get the best sound.
If you're using the body - pack transmitter, put fresh alkaline batteries in it. The battery life is about 8 hours, so you should be good for a decent - length event. Attach the omnidirectional lavalier microphone to your clothing and connect it to the transmitter. For the handheld transmitter, just insert the batteries and you're ready to go.
When you're in a large venue or outdoors, the advanced dipole antenna on the receiver will help extend the operating range. Keep in mind that the typical range is 200 feet (60 meters), but this can vary depending on the environment.
As for maintenance, keep the equipment clean. Wipe the receiver, transmitters, and microphone with a soft, dry cloth. Don't expose the system to extreme temperatures. The operating temperature range is from 40°F (4°C) to 110°F (43°C).
If you're not using the system for a while, remove the batteries from the transmitters to prevent leakage. Also, store the system in a safe place where it won't get damaged. This way, your Audio Technica ATW-901a/L will keep performing well for a long time.
