The mic gain and timeout settings were there before, but thank you for reminding me. Mine was set to 3 seconds and the firmware update reset it to 5, so I went back and fixed it after reading your msg.
I find that battery life is better with the shorter timeout and if I need constant input (such as rapid-paced GPS directions in a city), a tap on the PTT button locks the SR10 channel open until I tap it again.
