Maintenance and repair of referee radio flags

I am able to repair defective radio flags. This includes checking and replacing batteries and electronic components such as transmitters and receivers if the signal is no longer working properly. I can also check and adjust the antenna for optimal signal transmission. In the case of mechanical defects such as a broken handle or worn buttons, I repair or replace the affected parts. After each repair, I test the radio flag thoroughly to ensure that it is fully functional again.
