When you power on the Versiv/TFS remote, it will go through a self test sequence. If your remote unit LEDs (lights) stay on and do not turn off, this could be due to a failed software update attempt. You may wish to try the following:
- Power off the unit.（关闭电源）
- Hold down the TALK and TEST keys.（同时按照TALK和TEST按钮）
- Keeping them held down, turn on the tester.（打开测试仪）
- All the lights will stay on.
- Using LinkWare PC, reflash/update the tester again via the USB port using the latest version of LinkWare PC Software.（通过软件更新仪器）
