Roger On is a versatile, intelligent product. It detects
which situation you are in and adapts its microphone
settings automatically.
For best speech understanding, always bring your
Roger microphone as close to the conversation
partner(s) as possible.
Adjust the length of the lanyard so that the Roger On
is within 20 cm / 8 inches to the mouth of the talker.
