SAFETY PRECAUTIONS
WARNING: Avoid personal injury and product damage by complying with the following important
operating and maintenance instructions.
Avoid Electric Shock
WARNING: To reduce the risk of an electric shock, perform only the instructions that are included in
this instruction manual. Refer all servicing to a qualified service technician.
Do not apply power to the TX until all components have been installed and all of the wiring has
been properly terminated. Failure to do so may result in damage to the product and this will void the
manufacturer’s warranty.
Do not attempt to terminate, change or un-install any of the wiring without first switching off the unit
and unplugging the power cord/s from the TX. Be sure to follow the correct shutdown procedure.
The power supply voltage must not exceed the supplier recommended VDC, otherwise the TX could
suffer irreparable damage and subsequent invalidation of the warranty.
Note:
•Do not connect the TX to the power if the power cord/s are damaged
•Do not plug the TX into the mains supply until all cables have been connected correctly
•Do not cut the power cord
Servicing
WARNING: Avoid electric shock! Opening or removing the cover may expose you to dangerous
voltages. Do not open the cover of this product and attempt service unless instructed to do so in the
operating instructions. Refer all servicing to qualified personnel only.
Cleaning, Water, Moisture, Open Flame
WARNING: Do not expose any component to moisture. Doing so can create electrical hazards or
render the component unusable. Exposure to moisture will also void the warranty on the system.
To protect this product against damage from moisture and open flames, do the following:
•Before cleaning, unplug this product from the AC outlet. Do not use liquid or aerosol cleaners.
Use a dry cloth for cleaning

Ventilation
WARNING: To protect this product against damage from overheating, do the following:
•This product has openings for ventilation to protect it from overheating. To ensure product reliability,
do not block or cover these openings
•Do not open this product
•Do not push objects through openings in the product or enclosure
•If the TX has been kept in cold conditions for a long time, keep it in a warm room no less than
2 hours before plugging it into the mains.
•Do not place the TX on top or underneath another device, as this could cause overheating
Placement
WARNING: Avoid personal injury and damage to this product! An unstable surface
may cause this product to fall. To protect this product against damage from breakage,
do the following:
•Place this product close enough to a mains AC outlet to accommodate the length of
the product power cord
•Route all power supply cords so that people cannot walk on, or place objects on,
or lean objects against them. This can pinch or damage the cords. Pay particular
attention to cords at plugs, outlets and the points where the cords exit the product
•Make sure the mounting surface or rack is stable and can support the size and
weight of this product
•Move any appliance and cart combination with care. Quick stops, excessive force,
and uneven surfaces may cause the appliance and cart to overturn
Grounding Terminal
WARNING: If this product is equipped with an external grounding terminal, attach one end of a
2.5mm to the grounding terminal; then, attach the other end of the wire to an earth ground, such as
an equipment rack that is grounded or CET.
