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.

Please do not throw items marked with this symbol in your bin. Recycle
your electricals and electronic devices free at your local recycling centre.
Search for your nearest recycling centre by visiting www.recyclenow.com.
Why recycle?
Unwanted electrical equipment is the UK’s fastest growing type of waste.
Many electrical items can be repaired or recycled, saving natural resources
and the environment. If you do not recycle, electrical equipment will end up
in landfill where hazardous substances will leak out and cause soil and
water contamination –harming wildlife and human health.
RNIB are proud to support your local authority in providing local recycling
facilities for electrical equipment.
To remind you that old electrical equipment can be recycled, it is now
marked with the crossed-out wheeled bin symbol. Please do not throw any
electrical equipment (including those marked with this symbol) in your bin.
What is WEEE?
The Waste Electrical or Electronic Equipment (WEEE) Directive requires
countries to maximise separate collection and environmentally friendly
processing of these items.
How are we helping?
In the UK, distributors including retailers must provide a system which
allows all customers buying new electrical equipment the opportunity to
recycle their old items free of charge. As a responsible retailer, we have met
the requirements placed on us by financially supporting the national network
of WEEE recycling centres established by local authorities. This is achieved
through membership of the national Distributor Take-back scheme (DTS).
