Using this Samson AirLine 77 AH7 K3 wireless fitness headset system is easy. First, make sure to insert a single AAA battery into the micro - transmitter on the headset. Once the battery is in, turn on the system. You're ready to go! The operating range is up to 300 feet in a line - of - sight situation, so you can move around freely during your fitness class or performance.
When using it, keep in mind that the headset is sweat - resistant, but it's still a good idea to wipe it down after a sweaty session. This will help maintain its performance and longevity. Also, since it uses True Diversity design, you don't have to worry too much about audio dropouts, but try to avoid having any large obstacles between the transmitter and the receiver.
For maintenance, when the battery runs out, simply replace it with a new AAA battery. If you're not using the system for a long time, remove the battery to prevent any potential damage. The mountable half - rack chassis allows you to keep the system organized. You can mount it wherever it's convenient for you. And the 1/4 - wave antennas should be kept in good condition, free from any damage or obstruction for the best signal.
