1.1 Important safety instructions
Read, follow, and retain for future reference all of the following safety instructions. Heed all
warnings on the unit and in the operating instructions before operating the unit.
1. Cleaning - Unplug the unit from the outlet before cleaning. Follow any instructions provided
with the unit. Generally, using a dry cloth for cleaning is sufficient, but a moist fluff-free cloth
or leather shammy may also be used. Do not use liquid cleaners or aerosol cleaners.
2. Heat Sources - Do not install the unit near any heat sources such as radiators, heaters,
stoves, or other equipment (including amplifiers) that produce heat.
3. Ventilation - Any openings in the unit enclosure are provided for ventilation to prevent over-
heating and ensure reliable operation. Do not block or cover these openings. Do not place the
unit in an enclosure unless proper ventilation is provided, or the manufacturer’s instructions
have been adhered to.
4. Water - Do not use this unit near water, for example near a bathtub, washbowl, sink, laun-
dry basket, in a damp or wet basement, near a swimming pool, in an outdoor installation, or
in any area classified as a wet location. To reduce the risk of fire or electrical shock, do not
expose this unit to rain or moisture.
5. Object and liquid entry - Never push objects of any kind into this unit through openings as
they may touch dangerous voltage points or short-out parts that could result in a fire or elec-
trical shock. Never spill liquid of any kind on the unit. Do not place objects filled with liquids,
such as vases or cups, on the unit.
6. Lightning - For added protection during a lightning storm, or when leaving this unit unattend-
ed and unused for long periods, unplug the unit from the wall outlet and disconnect the cable
system. This will prevent damage to the unit from lightning and power line surges.
7. Controls adjustment - Adjust only those controls specified in the operating instructions.
Improper adjustment of other controls may cause damage to the unit. Use of controls or
adjustments, or performance of procedures other than those specified, may result in hazard-
ous radiation exposure.
8. Overloading - Do not overload outlets and extension cords. This can cause fire or electrical
shock.
9. Power cord and plug protection - Protect the plug and power cord from foot traffic, being
pinched by items placed upon or against them at electrical outlets, and its exit from the unit.
For units intended to operate with 230 VAC, 50 Hz, the input and output power cord must
comply with the latest versions of IEC Publication 227 or IEC Publication 245.
10. Power disconnect - Units with or without ON/OFF switches have power supplied to the unit
whenever the power cord is inserted into the power source. The power cord is the main
power disconnect device for switching off the voltage for all units.
11. Power sources - Operate the unit only from the type of power source indicated on the label.
Before proceeding, be sure to disconnect the power from the cable to be installed into the
unit.
12. Servicing - Do not attempt to service this unit yourself. Opening or removing covers may
expose you to dangerous voltage or other hazards. Refer all servicing to qualified service per-
sonnel.
13. Damage requiring service - Unplug the unit from the main AC power source and refer servic-
ing to qualified service personnel when any damage to the equipment has occurred, such as:
– the power supply cord or plug is damaged;
– exposure to moisture, water, and/or inclement weather (rain, snow, etc.);
– liquid has been spilled in or on the equipment;
– an object has fallen into the unit;
– unit has been dropped or the unit cabinet is damaged;
– unit exhibits a distinct change in performance;
