EM120 Radio Module Support Bulletin
Issue Summary
Users may report that the RTS icon is missing or that the radio module is not being detected by the tablet. Standard troubleshooting steps—such as toggling Airplane Mode, removing/re-attaching the radio, or rebooting—do not fix the issue.
This is typically caused by the EM120 radio module driver not being installed, which must be added manually.
