Important Safety Instructions

WARNING: 

There are no user serviceable parts inside. Refer all servic-

ing to qualified service personnel.

WARNING: 

To reduce the risk of fire or electric shock, do not expose 

the unit to moisture or water. Do not expose the unit to dripping or splash-

ing. Do not place objects filled with liquids, such as vases, on the unit. Do 

not allow foreign objects to get into the enclosure. If the unit is exposed 

to moisture, or a foreign object gets into the enclosure, immediately dis-

connect the power cord from the wall. Take the unit to a qualified service 

person for inspection and necessary repairs.
Read all the instructions before connecting or operating the component. 
Keep this manual so you can refer to these safety instructions.
Heed all warnings and safety information in these instructions and on the 

product itself. Follow all operating instructions.
Clean the enclosure only with a dry cloth or a vacuum cleaner.
Do not use this unit near water.

You must allow a minimum 10 cm or 4 inches of unobstructed 

clearance around the unit.

 Do not place the unit on a bed, sofa, rug, 

or similar surface that could block the ventilation openings. If the unit is 

placed in a bookcase or cabinet, there must be ventilation of the cabinet 

to allow proper cooling. 
Keep the component away from radiators, heat registers, stoves, or any 

other appliance that produces heat.
The unit must be connected to a power supply only of the type and voltage 

specified on the rear panel. (USA: 120 V/60Hz, EC: 230V/50Hz)
Connect the component to the power outlet only with the supplied power 

supply cable or an exact equivalent. Do not modify the supplied cable. A 

polarized plug has two blades, with one wider than the other. A grounding 

plug has two blades plus a third grounding prong. These are provided for 

your safety. Do not defeat grounding and/or polarization safety provisions. 

If the supplied plug does not fit your outlet, please consult an electrician 

for replacement of the obsolete outlet. Do not use extension cords. 
The main plug of the power cordset is a disconnect device of the appa-

ratus. In order to completely disconnect the apparatus from the supply 

mains, the main plug of the power cordset should be unplugged from the 

mains (AC) outlet. The stand-by LED indicator will not be lit up to show 

the power cord is unplugged.
Do not route the power cord where it will be crushed, pinched, bent, ex-

posed to heat, or damaged in any way. Pay particular attention to the 

power cord at the plug and where the cord exits the back of the unit.
The power cord should be unplugged from the wall outlet during a lightning 

storm or if the unit is to be left unused for a long period of time.
Use only accessories specified by the manufacturer.
Use only with a cart, stand, rack, bracket or shelf system recommended 

by Rotel. Use caution when moving the unit in a stand or rack to avoid 

injury from a tip-over.
Use Class 2 wiring for speaker connections to ensure proper installation 

and minimize the risk of electrical shock.
Immediately stop using the component and have it inspected and/or ser-

viced by a qualified service agency if:
•  The power supply cord or plug has been damaged.
•  Objects have fallen or liquid has been spilled into the unit.
•  The unit has been exposed to rain.
•  The unit shows signs of improper operation
•  The unit has been dropped or damaged in any way

WARNING: 

The master power switch is located on the rear panel. The 

unit must be located in the open area allowing unobstructed access to 

the main power switch.

This symbol means that this unit is double insulated. 
An earth or ground connection is not required.
