NAS-50HDE.GB.2-890-157-11(1)

 Completely disconnect the power cord (mains 

lead) from the wall socket (mains) if it is not going 

to be used for an extended period of time. When 

unplugging the unit, always grip the plug. Never 

pull the cord itself.

 Should any solid object or liquid get into the unit, 

unplug the unit, and have it checked by qualified 

personnel before operating it again.

 The AC power cord can be changed only by a 

qualified service facility.

 Do not place the unit in an inclined position or 

in locations that are extremely hot, cold, dusty, 

dirty, or humid or lacking adequate ventilation, 

or subject to vibration, direct sunlight or a bright 

light.

 Be careful when placing the unit or speakers 

on surfaces that have been specially treated (for 

example, with wax, oil, polish) as staining or 

discoloration of the surface may result.

 If the unit is brought directly from a cold to a 

warm location or is placed in a very damp room, 

moisture may condense on the lens inside the 

CD player, and cause the unit to malfunction. In 

this situation, remove the disc, and leave the unit 

turned on for about an hour until the moisture 

evaporates.

 Heat buildup on the unit during operation is 

normal and is not cause for alarm.

 Do not touch the cabinet if it has been used 

continuously at a high volume because the cabinet 

may have become hot.

 Do not block the ventilation holes on the bottom 

of this unit. Doing so will prevent the heat 

produced by the unit’s amplifier to build up, which 

may cause the unit to malfunction. Make sure 

these holes are free from any obstruction.

Do not move the unit while a CD is inserted. Doing 

so may damage the CD.

This speaker system is not magnetically shielded, 

and the picture on nearby TV sets may become 

magnetically distorted. In this situation, turn off the 

TV, wait 15 to 30 minutes, and turn it back on. If 

there is no improvement, move the speakers far away 

from the TV. 

CDs reproduce sound with considerably less noise 

than vinyl records. For this reason, if you raise the 

volume while listening to a segment containing only 

noise (as you might do in the case of a vinyl record), 

a sudden output of high-volume sound may cause 

damage to the speakers. 

Make sure to lower the volume before the start of 

playback.

Keep the volume at a moderate level out of 

consideration of your neighbors, especially at night.

Audio data and system settings stored on the unit’s 

hard disk may be lost during repairs done to the 

unit. Before taking the unit in for repairs, it is 

recommended that you record the settings on a piece 

of paper and that you use the Back Up function 

to back up the data to a shared folder on your 

computer or a USB hard disk drive (see “Backing up 

and restoring audio data” on page 95).

Data on the unit’s HDD is subject to damage during 

normal operations. To prevent the loss of data, you 

should back up the data on a regular basis. Please 

note that we cannot take responsibility for any data 

that may be lost or affected during normal use or 

repairs.

Clean this unit with a soft cloth slightly moistened 

with a mild detergent solution. Do not use any type 

of abrasive pad, scouring powder, or solvent, such as 

thinner, benzine, or alcohol. 

Before you unplug the power cord from the wall 

outlet, make sure that the unit is in standby mode 

(the On/Standby indicator is lit up red or orange). 

If you unplug the power cord while the unit is 

operating (the On/Standby indicator lit up green), 

data that was recorded may be lost or the unit may 

malfunction.
