How do I set up hands-free operation on my walkie talkie?

You can use hands-free operation in two ways: iVOX (without accessories) by pressing the menu button until iVOX appears and selecting On/Off, or VOX (with accessories) by turning off the radio, plugging in the VOX accessory into the accessory port, and turning the radio back on. Note there is a short delay between speaking and transmission. (Page 1)
