When the Unit is in Use

 Do not place heavy objects on the unit as this may cause it to fall or break which may 

result in personal injury and/or property damage.In addition,the object itself may fall off 

and cause injury and/or damage.

 Make sure that the volume control is set to minimum position before power is switched on.

Loud noise produced at high volume when power is switched on can impair hearing.

 Do not operate the unit for an extended period of time with the sound distorting. 

This is an indication of a malfunction, which in turn can cause heat to generate and 

result in a fire.

 Contact your dealer as to the cleaning. If dust is allowed to accumulate in the unit 

over a long period of time, a fire or damage to the unit may result.

 If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. 

Clean it periodically. In addition, insert the plug in the wall outlet securely.

 Switch off the power, and unplug the power supply plug from the AC outlet for safety 

purposes when cleaning or leaving the unit unused for 10 days or more. 

Doing otherwise may cause a fire or electric shock.

When Installing the Unit

 Never plug in nor remove the power supply plug with wet hands, as doing so may cause 

electric shock.

 When unplugging the power supply cord, be sure to grasp the power supply plug; never 

pull on the cord itself. Operating the unit with a damaged power supply cord may cause 

a fire or electric shock.

 When moving the unit, be sure to remove its power supply cord from the wall outlet. 

Moving the unit with the power cord connected to the outlet may cause damage to the 

power cord, resulting in fire or electric shock. When removing the power cord, be sure 

to hold its plug to pull.

 Do not block the ventilation slots in the unit's cover.

Doing so may cause heat to build up inside the unit and result in fire.

 Avoid installing the unit in humid or dusty locations,in locations  exposed to the direct 

sunlight, near the heaters,or in locations generating sooty smoke or steam as doing

otherwise may result in fire or electric shock.

CAUTION

4-16Ω low impedance output 

This output allows connection of low impedance loudspeakers without transformers

,

When two or more loudspeakers are used ensure that they are wired in 

such a way in Series, or in Parallel, or in Series & Parallel Combination that total load 

impedance remains between 4Ω and 16Ω.
