Combined with all of the steps in the 'Test Kit - Quick Start Guide':
Truety wireless modules are designed to optimize their communication parameters based on the RF environment, maximizing transmission performance and battery life.
Typically, once a wireless module has been installed, its location is permanent. This differs from signal testing scenarios where the module will be moved to different locations during testing. For the purpose of signal testing, you will use only the device rejoin request function in the Truety CX App.

See the attached PDF for instructions on signal testing.
