Using the Heil Sound Pro 7 headset is easy. First, put the headset on your head and adjust it for a comfortable fit. The ear pads should cover your ears well to get the best noise - reduction effect. Use the audio balance control to make sure the sound in both ears is the same. If you're having trouble hearing weak signals, flip the phase - reversal switch. To use the monitor jack, just plug in headphones for a second operator. When using the microphone, speak clearly into it. For the PTT switch, press it when you want to transmit your voice. Keep the headset away from extreme heat, cold, and moisture. If the ear pads get dirty, you can wash the cotton covers. Also, be careful with the cables, especially the coiled one, to avoid tangling. Periodically check the connections to make sure they're secure. If you need to use an adapter, make sure it's from the AD - 1 Series.
