FCC regulations

NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO 

OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS 

TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER 

AUTHORITY TO OPERATE THE EQUIPMENT.

This equipment has been tested and found to comply with the 

limits for a Class B digital device, pursuant to Part 15 of the 

FCC Rules. These limits are designed to provide reasonable 

protection against harmful interference in a residential 

installation. This equipment generates, uses and can radiate radio 

frequency energy and, if not installed and used in accordance with the 

instructions, may cause harmful interference to radio communications. 

However, there is no guarantee that interference will not occur in a 

particular installation.
If this equipment does cause harmful interference to radio or television 

reception, which can be determined by turning the equipment off and 

on, the user is encouraged to try to correct the interference by one or 

more of the following measures:
- Re-orient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-  Connect the equipment into an outlet on a circuit different from that to 

which the receiver is connected.

-  Consult the dealer or an experienced radio/TV technician for help.

Ventilation

IMPORTANT

 – The unit will become hot when in use. Do not stack 

multiple units on top of each other. Do not place in an enclosed area 

such as a bookcase or in a cabinet without sufficient ventilation. 
Ensure that small objects do not fall through any ventilation grille. If this 

happens, switch off immediately, disconnect from the mains supply and 

contact your dealer for advice.

Positioning

Choose the installation location carefully. Avoid placing it in direct 

sunlight  or  close  to  a  source  of  heat.  No  naked  flame  sources,  such 

as lighted candles, should be placed on the unit. Also avoid locations 

subject to vibration and excessive dust, cold or moisture. The unit can 

be used in a moderate climate. 
This unit must be installed on a sturdy, level surface. Do not place in a 

sealed area such as a bookcase or in a cabinet. Do not place the unit on 

an unstable surface or shelf. The unit may fall, causing serious injury to 

a child or adult as well as serious damage to the product. Do not place 

other equipment on top of the unit.
Due to stray magnetic fields, turntables or CRT TVs should not be located 

nearby due to possible interference.
Electronic audio components have a running in period of around a week 

(if used several hours per day). This will allow the new components to 

settle down and the sonic properties will improve over this time.

Power sources 

The unit should be operated only from the type of power source indicated 

on the marking label. If you are not sure of the type of power-supply to 

your home, consult your product dealer or local power company. 
To turn the unit off, switch off on the front panel. If you do not intend to 

use this unit for a long period of time, unplug it from the mains socket.

Overloading 

Do not overload wall outlets or extension cords as this can result in a risk 

of fire or electric shock. Overloaded AC outlets, extension cords, frayed 

power cords, damaged or cracked wire insulation and broken plugs are 

dangerous. They may result in a shock or fire hazard. 
Be sure to insert each power cord securely. To prevent hum and noise, 

do not bundle the interconnect leads with the power cord or speaker 

leads.

Cleaning

To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any 

cleaning fluids containing alcohol, ammonia or abrasives. Do not spray 

an aerosol at or near the unit.

Battery disposal

Batteries may contain substances harmful to the environment. Please 

dispose of any discharged batteries with due consideration and in 

accordance with local environmental/electronic recycling guidelines.

Loudspeakers

Before making any connections to loudspeakers, make sure all power is 

turned off and only use suitable interconnects.

Servicing 

These units are not user serviceable. Never attempt to repair, 

disassemble or reconstruct the unit if there seems to be a problem. 

A serious electric shock could result if this precautionary measure is 

ignored. In the event of a problem or failure, please contact your dealer.
