IMPORTANT SAFETY INSTRUCTIONS

Please read all of these instructions and save them for future reference. Follow all
warnings and instructions marked on the unit.
•
Do not obstruct air vents in the rear panel. Do not insert objects through any
apertures.
•
Do not use a damaged or frayed power cord.
•
Unplug the unit before cleaning. Clean with a damp cloth only. Do not spill
liquid on the unit.
•
Ensure adequate airflow around the unit to prevent overheating. As this is a Class
A unit, we recommend leaving a blank 1U panel above the unit to aid ventilation.
•
Unplug the unit and refer servicing to qualified service personnel under the
following conditions: If the power cord or plug is damaged; if liquid has entered
the unit; if the unit has been dropped or the case damaged; if the unit does not
operate normally or exhibits a distinct change in performance. Adjust only those
controls that are covered by the operating instructions.
•
Do not defeat the safety purpose of the polarised or grounding-type plug. A
polarised plug has two blades with one wider than the other. A grounding type
plug has two blades and a third grounding prong. The wider blade or the third
prong is provided for your safety. When the plug provided does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.
WARNING: THIS UNIT MUST BE EARTHED BY THE POWER CORD.
UNDER NO CIRCUMSTANCES SHOULD THE MAINS EARTH BE
DISCONNECTED FROM THE MAINS LEAD.
This unit is supplied pre-configured to operate only at the voltage indicated on the
rear panel. Ensure correct mains voltage is available and the correct fuse value is fitted
before connecting to the mains supply. To avoid the risk of fire, replace the mains fuse
only with the correct value fuse, as marked on the rear panel. The internal power
supply unit contains no user serviceable parts. Refer all servicing to a qualified service
engineer, through the appropriate Focusrite dealer.
RACK VENTILATION: AS THE TWINTRAK PRO IS A CLASS A
DEVICE, PLEASE ENSURE IT IS PLACED TOWARDS THE BOTTOM
OF YOUR EQUIPMENT RACK, WITH SUFFICIENT SPACE ABOVE
AND BELOW FOR VENTILATION.
