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:

Thank you for purchasing this SHARP product.  
For the best performance, read this manual care-
fully.  It will guide you in operating your SHARP
product.
 ●  
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.

MAINTENANCE 
Internal care
Do not touch the Laser pickup lens. If fingerprints
or dust accumulate on the pickup, clean it gently
with a dry cotton swab.
Dirty heads, capstan or pinch roller can cause
poor sound and tape jams. Clean these parts
with a cotton swab moistened with commercial
head/pinch roller cleaner or isopropyl alcohol.
After long use, the deck’s heads and capstan
may become magnetised, causing poor sound.
Demagnetise these parts once every 30 hours of
playing/recording by using a commercial tape
head demagnetiser. Read the demagnetiser’s
instructions carefully before use.
External care
Periodically wipe the cabinet with a soft cloth and
a diluted soap solution, then wipe with a dry cloth.
Do not use chemically treated cleaning cloths or
other chemicals.

PRECAUTIONS 
General
Do not use oil, solvents, petrol, paint thinners or
insecticides on the unit.
Do not expose the unit to moisture, to tempera-
tures 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 compu-
ters, facsimiles, etc.) which generates electrical
noise.
Hold the AC power plug by the head when re-
moving it from the AC socket, since pulling the
lead can damage internal wires.
When cleaning the heads, pinch roller, etc,
remove the AC power plug from the wall socket
as the unit contains high voltages.
Do not remove the outer cover, as this may result
in electric shock. Refer internal service to your
local SHARP service 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,
set the FUNCTION switch to STAND-BY and
then to ON again.
If an electrical storm is taking place near you, it
is suggested 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.
Condensation
Sudden temperature changes, storage or operation
in an extremely humid environment may cause con-
densation inside 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.
AC power lead
If the unit will not be used for a long period of
time, remove the AC power lead from the AC
socket.
Connection of the AC power lead to the unit
disconnects the batteries.
Never use a power lead other than the one
supplied. Use of a power lead other than the one
supplied may cause an electric shock or fire.
Battery use
Insert the batteries as shown on the rear panel
of the main unit and in the battery compartment
of the remote control.
Replace all old batteries with new ones at the
same time.
Do not mix old and new batteries.
Remove the batteries if they are weak or if the
unit will not be used for long periods of time. This
will prevent potential damage due to battery
leakage.
Caution:
Do not use rechargeable batteries (nickel-cadmium
battery, etc.).
Battery replacement:
For the main unit:
Replace the batteries when they become weak
and/or recording or playback is impaired. This may
occur even though radio broadcasts are audible.
For the remote control:
Replace the batteries if the operating distance is
reduced or if the operation becomes erratic.
Care of compact discs
Compact discs are fairly resistant to damage, how-
ever 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
For playback, use normal or low-noise tape for
the best sound. (Metal or CrO
2
 tape is not rec-
ommended.)
For recording, use only normal tape.
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 compart-
ment, 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 corre-
sponding side from being erased. Cover the tab
holes with adhesive tape to erase or record
again.
