7
Mode 4
– Aux Mode- enables an external device such as an MP3 player or
mobile phones (as a playback device) to be connected to the Duo-Comm 2.
The headset microphone will be disabled in this mode. Please note that the
volume setting of the external device is used when in Aux Mode so please
ensure the volume levels are low on the device before connecting to the
Duo-Comm 2.
Adjust each volume control to suit your needs. The supplied headset
features an in-line volume control located around 350mm (14 inches) from
the headset. This in-line volume control varies the volume level from the
Duo-Comm 2. Please ensure that the rotary dial on the in-line volume
control is set roughly to a middle position before testing the volume level
using the volume control on the Duo-Comm 2. If you cannot hear any audio
from the headset it is likely that this rotary dial requires further adjustment.
To increase the volume, the rotary dial must be rotated clockwise. To
decrease the volume the rotary dial must be rotated anti-clockwise.
Please test the headset microphone volume by ringing a friend or colleague
so that they can tell you if the microphone volume needs adjusting. Try to
avoid high levels of volume on the microphone, as this may be
uncomfortable for the person listening to you.
