GIRN is a radio system used by the Ministry of Health in Malaysia for communication between emergency responders and hospitals. It allows for open communication channels coordinated by the National Security Council. The system requires users to identify themselves clearly, speak one at a time, keep messages brief, and say "over" to indicate they have finished transmitting. Key elements for effective communication over GIRN radios include accuracy, clarity, and using proper procedures like pressing the push-to-talk button to transmit and releasing it to receive transmissions. The system is used in various emergency communication scenarios.
