2. ATTENTION

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.

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 Sound Choice 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.

Due to product upgrades, some of the features and specifications in the user manual may not match the actual functions.  We 

are sorry for any inconvenience this may cause, and thank you for your kind understanding.

CAUTION

An all-pole mains switch with a contact separation of at least 3 mm in each pole shall be incorporated in the electrical 

installation of the building.
