SPECIAL NOTES 
NOTE FOR USERS IN THE U.K.   
SERVICE INFORMATION  
In the unlikely event of your equipment requiring repair,
please contact the dealer or supplier from whom it was
purchased. Where this is not possible, please contact the
telephone number listed below. You will then be given
details of how to obtain service. 
- 0345-125387 -  
Please note; all calls will be charged at local rate.  
 
Certain replacement parts and accessories may be ob-
tained from our main parts distributor.
         WILLOW VALE ELECTRONICS LTD.
In the unlikely event of this equipment requiring repair
during the guarantee period, you will need to provide
proof of the date of purchase to the repairing company.
Please keep your invoice or receipt, which is supplied at
the time of purchase.
The mains lead of this product is fitted with a non-rewire-
able (moulded) plug incorporating a 3A fuse. Should the
fuse need to be replaced, a BSI or ASTA approved BS
1362 fuse marked     or     and of the same rating as
above, which is also indicated on the pin face of the plug
must be used.   
     
Always refit the fuse cover after replacing the fuse. Never
use the plug without the fuse cover fitted.   
     
In the unlikely event of the socket outlet in your home
not being compatible with the plug supplied, cut-off the
mains plug and fit an appropriate type.   
     
DANGER:   
The fuse from the cut-off plug should be removed and
the cut-off plug destroyed immediately and disposed of
in a safe manner.   
     
Under no circumstances should the cut-off plug be in-
serted elsewhere into a 13A socket outlet as a serious
electric shock may occur.   
     
To fit an appropriate plug to the mains lead, follow the
instructions below:   
     
IMPORTANT:   
The wires in the mains lead are coloured in accordance
with the following code:   
   
Blue                              :  Neutral     
Brown                          :  Live     
     
As the colours of the wires in the mains lead of this
product may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows:
 ●  
The wire which is coloured blue must be connected to
the plug terminal which is marked N or coloured black. 
 ●  
The wire which is coloured brown must be connected
to the plug terminal which is marked L or coloured red.
Ensure that neither the brown nor the blue wire is con-
nected to the earth terminal in your three pin plug.   
     
Before replacing the plug cover, make sure that:   
 ●  
If the new fitted plug contains a fuse, its value is the
same as that removed from the cut-off plug.
 ●  
The cord grip is clamped over the sheath of the mains
lead and not simply over the lead wires.
     
IF YOU HAVE ANY DOUBT, CONSULT A QUALIFIED
ELECTRICIAN.

When the ON/STAND-BY button is set at STAND-BY po-
sition, mains voltage is still present inside the unit.
When the ON/STAND-BY button is set at STAND-BY po-
sition and the clock is displayed, the unit may be brought
into operation by the timer mode or remote control.
Warning:
This unit contains no user serviceable parts. Never remove
covers unless qualified to do so. This unit contains danger-
ous voltages, always remove mains plug from the socket
before any service operation and when not in use for a long
period.
Recording and playback of any material may require con-
sent, which SHARP is unable to give. Please refer partic-
ularly to the provisions of the Copyright Act 1956, the
Dramatic and Musical Performers Protection Act 1958, the
Performers Protection Acts 1963 and 1972 and to any
subsequent statutory enactments and orders.

PRECAUTIONS 
General
‘;ease make sure that the unit is positioned in a well ven-
tilated area and that there is at least 10 cm (4") of free
space along the sides and back. There must also be a
minimum of 50 cm (19-11/16") of free space on the top
of the unit.
Do not use oil, solvents, petrol, paint thinners or insecti-
cides on the unit.
Do not expose the unit to moisture, to temperatures higher
than 60˚C (140˚F) or to extreme low temperatures.
Keep the unit away from direct sunlight, strong magnetic
fields, excessive dust, humidity and electronic/electrical
equipment (home computers, facsimiles, etc.) which gen-
erates electrical noise.
Hold the AC power plug by the head when removing it
from the AC socket, since pulling the lead can damage
internal wires.
When cleaning the heads, pinch rollers, etc, remove the
AC power plug from the AC socket as the unit contains
high voltages.
Do not remove the outer cover, as this may result in elec-
tric shock. Refer internal service to your local SHARP ser-
vice facility.
Use the unit on a firm, level surface free from vibration,
and do not place anything on the top of the unit.
If the unit does not work properly whilst in use, disconnect
the AC power lead from the AC socket. Plug the AC power
lead back in, and then press the POWER button to turn
the power on.
If an electrical storm is taking place near you, it is sug-
gested that you disconnect the AC power lead from the
AC socket for safety.
Warning:
The voltage used must be the same as that specified on
this unit. Using this product with a higher voltage other than
which is specified is dangerous and may result in a fire or
other type of accident causing damage. SHARP will not be
held responsible for any damage resulting from use of this
unit with a voltage other than that which is specified.
Volume control
The sound level at a given volume setting depends on a
combination of speaker efficiency, location and various other
factors.
It is advisable to avoid exposure to high volume levels, which
occur whilst turning the unit on with the volume control set-
ting up high, or whilst continually listening at high volumes.
Condensation
Sudden temperature changes, storage or operation in an
extremely humid environment may cause condensation in-
side the cabinet (CD pickup, tape heads, etc.) or on the
transmitter LED on the remote control.
Condensation can cause the unit to malfunction.
If this happens, leave the power on with no disc (or cassette)
in the unit until normal playback is possible (about 1 hour).
Wipe off any condensation on the transmitter LED with a
soft cloth before operating the unit.
Care of compact discs
Compact discs are fairly resistant to damage, however
mistracking can occur due to an accumulation of dirt on the
disc surface. 
Follow the guidelines below for maximum enjoyment from
your CD collection and player.
Do not write on either side of the disc, particularly the non-label
side. Signals are read from the non-label side.  Do not mark
this surface.
Keep your discs away from direct sunlight, heat, and excessive
moisture.
Always hold the CDs by the edges. Fingerprints, dirt, or water
on the CDs can cause noise or mistracking. If a CD is dirty
or does not play properly, clean it with a soft, dry cloth, wiping
straight out from the centre, along the radius.
Cassette tape
This deck features an auto tape selector. Just load a tape,
and the tape formula being used will be sensed automat-
ically.
For playback, use normal (low-noise), CrO
2
 or metal tape
for the best sound. For recording, use normal (low-noise)
or CrO
2
 tape. Metal tape cannot be used for recording.
Do not use C-120 tapes, tapes with large diameter reels,
or poor-quality tapes, as they may cause malfunctions.
Before loading a tape into the cassette compartment,
tighten the slack with a pen or pencil.
Cassettes have removable tabs which prevent accidental
recording or erasing from taking place. Removing the tab
will protect the corresponding side from being erased.
Cover the tab holes with adhesive tape to erase or record
again.
When covering erasure prevention tab holes, do not cover
the CrO
2
 and metal detection holes located between them.
Otherwise, the deck will sense the tape as normal tape.
TAPE 1: Playback only.
TAPE 2: Playback or record.
