Using the Shure ADX2/B87A G57 is easy. First, insert the SB920A rechargeable batteries into the transmitter. You can also use the optional docking charger for charging. Once the batteries are in, turn on the transmitter. You can choose the standard or high - density transmission mode according to your needs.

When using it on stage, you can use the ShowLink remote control to adjust settings like volume or frequency without having to leave the stage. The transmitter will automatically avoid interference thanks to the Diversity ShowLink feature.
Here are some important things to note. Don't expose the transmitter to extreme temperatures. The operating temperature range is from - 18°C (0°F) to 50°C (122°F), and the storage temperature range is from - 29°C (- 20°F) to 74°C (165°F). Also, keep the metal case dry as it can resist moisture but too much water may still cause problems.
For maintenance, after each use, put the transmitter back in the protective carrying case. If the battery runtime starts to get shorter, it might be time to replace the SB920A batteries. And don't forget to refer to the user manual if you have any other questions.
