Transmitting Technique
Use the transmitting techniques below to help make sure the transmitted message is clear:
Before starting.
- Check the receiver volume is set for the best sound level.
- Listen out on the frequency you are going to use to make sure you don’t interfere with
someone else.
- Make sure you know how to operate the two-way radio, be familiar with the buttons.
Talk directly into the two-way radio (do not turn your head away when talking).
Keep the two-way radio steady and hold it up to your mouth (your mouth shouldn’t touch it).
Try and speak normally. Speak slowly and clearly.
Pause slightly before and after numbers as this makes it easier to understand.
Avoid using ‘um’ or ‘er’ as this will cause confusion.
Press the transmit button fully before speaking and do not release it until the message is
complete. Only press the transmit button when you are ready to speak.
Remember to speak slowly and clearly and use standard words and phrases as much as
possible.
