What should operators avoid when using signals or phrases?

When using signals or phrases, operators should avoid slang and racial or ethnic terms because it is essential to maintain clarity, professionalism, and respect in communication. Slang can lead to misunderstandings and may not be universally understood by all individuals, especially in a diverse work environment. Additionally, the use of racial or ethnic terms can create an environment that is not inclusive and may lead to feelings of discomfort or offense among colleagues or clients, which is detrimental to effective communication and teamwork. Maintaining a neutral and professional tone fosters a more constructive and respectful working atmosphere, allowing information to be conveyed clearly without the risk of misinterpretation or alienation.
